MANAGEMENT OF ENDOCRINE DISEASE: Long-term outcomes of the treatment of central precocious puberty.
    European journal of endocrinology, 2016, Volume: 174, Issue:3

    GnRH analogues (GnRHa) are the treatment of choice for central precocious puberty (CPP), with the main objective to recover the height potential compromised by the premature fusion of growth cartilages. The aim of this review was to analyze long-term effects of GnRHa on height, body weight, reproductive function, and bone mineral density (BMD) in patients with CPP, as well as the potential predictors of outcome. Because randomized controlled trials on the effectiveness and long-term outcomes of treatment are not available, only qualified conclusions about the efficacy of interventions can be drawn. GnRHa treatment appears to improve adult height in girls with CPP, especially if diagnosed before the age of 6, whereas a real benefit in terms of adult height is still controversial in patients with the onset of puberty between 6 and 8 years of age. No height benefit was shown in patients treated after 8 years. Gonadal function is promptly restored in girls after cessation of treatment, and reproductive potential appears normal in young adulthood. Data are conflicting on the long-term risk of polycystic ovarian syndrome in both treated and untreated women. Fat mass is increased at the start of treatment but normalizes thereafter, and GnRHa itself does not seem to have any long-term effect on BMI. Similarly, analogue treatment does not appear to have a negative impact on BMD. Owing to the paucity of data available, no conclusions can be drawn on the repercussions of CPP and/or its treatment on the timing of menopause and on the health of the offspring.

Is a GnRH antagonist protocol better in PCOS patients? A meta-analysis of RCTs.
    PloS one, 2014, Volume: 9, Issue:3

    To review published randomized controlled trials (RCTs) evaluating the outcomes of in vitro fertilization/intra-cytoplasmic sperm injection (IVF/ICSI) utilization of gonadotropin-releasing hormone (GnRH) antagonists for ovarian stimulation in polycystic ovarian syndrome (PCOS) patients compared with classic luteal long agonist protocols.. A meta-analysis of prospective randomized trials published in English between 2002 and 2013.. Nine RCTs examining PCOS patients undergoing IVF/ICSI including 588 women who underwent long agonist protocols and 554 women who underwent GnRH antagonist protocols.. Clinical pregnancy rate (CPR), ongoing pregnancy rate (OPR) and ovarian hyperstimulation syndrome (OHSS) rate.. Nine RCTs were included in this analysis. The CPR-per-embryo transferred was similar in the two groups (relative risk (RR): 0.97, 95% confidence interval (CI): 0.85-1.10). Non-significant estimates comparing the two protocols were found for age, BMI, total dose of gonadotropin administered, number of days of stimulation and number of oocytes retrieved. After meta-analysis of 4 of the RCTs, it was concluded that a GnRH antagonist protocol is better than an agonist long protocol to reduce the rate of severe OHSS (odds ratio (OR): 1.56, 95% CI: 0.29-8.51).. With respect to CPR, a GnRH antagonist protocol is similar to a GnRH agonist long protocol. However, for severe OHSS, a GnRH antagonist protocol is significantly better in PCOS patients.

Polycystic ovary syndrome: pathophysiology and outcome with in vitro fertilization.
    Fertility and sterility, 1996, Volume: 65, Issue:1

    To assess the efficacy of IVP-ET in infertile women with the polycystic ovary syndrome (PCOS) and to provide a comprehensive review of contemporary therapeutic options and their complications as reflected in the current literature.. Pertinent studies in medical literature identified through computerized bibliographic search and via manual review of relevant scientific publications.. In vitro fertilization and ET is an effective therapy for PCOS patients who are refractory to ovulation induction in vivo or who have coexisting infertility factors. The use of GnRH agonist (GnRH-a) is associated with significant reductions in the incidence of pregnancy loss and may improve fertilization and cleavage rates. In the PCOS patient, the use of purified FSH preparations does not appear to improve pregnancy rates nor other clinical parameters when compared with hMG. Severe ovarian hyperstimulation syndrome (OHSS) is an important consideration when PCOS patients undergo superovulation protocols. Strategies for OHSS prevention include the use of intravenous albumin immediately after oocyte retrieval, triggering of ovulation with a GnRH-a, or withholding menotropin therapy for several days before hCG administration. Cryopreservation of all embryos for future transfer in an artificial cycle has also proven to be an effective alternative in PCOS patients at high risk for severe OHSS.. Pregnancy rates for PCOS patients undergoing IVF-ET are comparable with those for women with tubal factor infertility. Therefore, IVF-ET should be offered to patients with PCOS who are refractory to conventional infertility modalities.

Ovarian hyperstimulation syndrome after superovulation using GnRH agonists for IVF and related procedures.
    Human reproduction (Oxford, England), 1992, Volume: 7, Issue:3

    Ovarian hyperstimulation syndrome (OHSS) is the most serious iatrogenic complication of ovarian stimulation. In severe cases, haemoconcentration, hypovolaemia, thromboembolism and death may result. It is reassuring that its incidence is not increased after ovarian stimulation for in-vitro fertilization despite very high serum oestradiol levels and large numbers of follicles and oocytes. This may be related to follicular aspiration, expert monitoring or low implantation rates. However, complete prevention has not been achieved despite the wide availability of ultrasound and oestradiol assays, thus presenting the clinician with a continuous challenge. Our aim is to analyse critically the most recent published series of OHSS in in-vitro fertilization and other assisted reproduction techniques using stimulation with gonadotrophin releasing hormone agonists (GnRHa) and human menopausal gonadotrophin (HMG). The main determining factor in the development of OHSS appears to be ovarian predisposition. Patients with polycystic ovarian disease are at a high risk of OHSS and therefore a small dose and slow start of HMG is recommended, tailoring the dosage according to the ovarian response. Accurate prediction by ultrasound and oestradiol assays and strict prevention by withholding human chorionic gonadotrophin (HCG) or cryopreservation of all the embryos have a major impact on the occurrence of OHSS. It is interesting that fixed-schedule IVF cycles, without detailed monitoring, are not associated with an increased incidence of OHSS. The use of GnRHa, despite expectations, is associated with a higher prevalence of OHSS. Luteal phase supplementation with progesterone rather than HCG should be used in cycles where oestradiol is greater than 2500 ng/l or where the number of oocytes exceeded 10.(ABSTRACT TRUNCATED AT 250 WORDS)

Endocrine Responses to Triptorelin in Healthy Women, Women With Polycystic Ovary Syndrome, and Women With Hypothalamic Amenorrhea.
    The Journal of clinical endocrinology and metabolism, 2023, Jun-16, Volume: 108, Issue:7

    Limited data exist regarding whether the endocrine response to the gonadotropin-releasing hormone receptor agonist (GnRHa) triptorelin differs in women with polycystic ovary syndrome (PCOS) compared with healthy women or those with hypothalamic amenorrhea (HA).. We compared the gonadotropin response to triptorelin in healthy women, women with PCOS, or those with HA without ovarian stimulation, and in women with or without polycystic ovaries undergoing oocyte donation cycles after ovarian stimulation.. The change in serum gonadotropin levels was determined in (1) a prospective single-blinded placebo-controlled study to determine the endocrine profile of triptorelin (0.2 mg) or saline-placebo in healthy women, women with PCOS, and those with HA, without ovarian stimulation; and (2) a retrospective analysis from a dose-finding randomized controlled trial of triptorelin (0.2-0.4 mg) in oocyte donation cycles after ovarian stimulation.. In Study 1, triptorelin induced an increase in serum luteinizing hormone (LH) of similar amplitude in all women (mean peak LH: healthy, 52.3; PCOS, 46.2; HA, 41.3 IU/L). The AUC of change in serum follicle-stimulating hormone (FSH) was attenuated in women with PCOS compared with healthy women and women with HA (median AUC of change in serum FSH: PCOS, 127.2; healthy, 253.8; HA, 326.7 IU.h/L; P = 0.0005). In Study 2, FSH levels 4 hours after triptorelin were reduced in women with at least one polycystic morphology ovary (n = 60) vs normal morphology ovaries (n = 91) (34.0 vs 42.3 IU/L; P = 0.0003). Serum anti-Müllerian hormone (AMH) was negatively associated with the increase in FSH after triptorelin, both with and without ovarian stimulation.. FSH response to triptorelin was attenuated in women with polycystic ovaries, both with and without ovarian stimulation, and was negatively related to AMH levels.

Pregnancy outcome and cost-effectiveness comparisons of artificial cycle-prepared frozen embryo transfer with or without GnRH agonist pretreatment for polycystic ovary syndrome: a randomised controlled trial.
    BJOG : an international journal of obstetrics and gynaecology, 2021, Volume: 128, Issue:4

    To compare the live birth rate and cost effectiveness of artificial cycle-prepared frozen embryo transfer (AC-FET) with or without GnRH agonist (GnRH-a) pretreatment for women with polycystic ovary syndrome (PCOS).. Open-label, randomised, controlled trial.. Reproductive centre of a university-affiliated hospital.. A total of 343 women with PCOS, aged 24-40 years, scheduled for AC-FET and receiving no more than two blastocysts.. The pretreatment group (n = 172) received GnRH-a pretreatment and the control group (n = 171) did not. Analysis followed the intention-to-treat (ITT) principle.. The primary outcome measure was live birth rate. Secondary outcome measures included clinical pregnancy rate, implantation rate, early pregnancy loss rate and direct treatment costs per FET cycle.. Among the 343 women randomised, 330 (96.2%) underwent embryo transfer and 328 (95.6%) completed the protocols. Live birth rate according to ITT did not differ between the pretreatment and control groups [85/172 (49.4%) versus 92/171 (53.8%), absolute rate difference -4.4%, 95% CI -10.8% to 2.0% (P = 0.45). Implantation rate, clinical pregnancy rate and early pregnancy loss rate also did not differ between groups, but median direct cost per FET cycle was significantly higher in the pretreatment group (7799.2 versus 4438.9 RMB, OR = 1.9, 95%CI 1.2-3.4, P < 0.001). Median direct cost per live birth was also significantly higher in the pretreatment group (15663.1 versus 8189.9 RMB, odds ratio [OR] = 1.9, 95% CI 1.2-3.8, P < 0.001).. Pretreatment with GnRH-a does not improve pregnancy outcomes for women with PCOS receiving AC-FET, but significantly increases patient cost.. For women with PCOS, artificial cycle-prepared FET with GnRH agonist pretreatment provides no pregnancy outcome benefit but incurs higher cost.

Fixed versus flexible antagonist protocol in women with predicted high ovarian response except PCOS: a randomized controlled trial.
    BMC pregnancy and childbirth, 2021, May-02, Volume: 21, Issue:1

    No previous study directly compares the fixed day-5 initiation versus the flexible initiation of GnRH antagonist administration in IVF/ICSI for those patients who are predicted as high ovarian responders without PCOS. To evaluate whether the number of oocytes retrieved is different by using the two GnRH antagonist protocols in Chinese women with predicted high ovarian response except PCOS.. No significant difference was observed between the fixed and flexible groups regarding the number of oocytes retrieved (16.72 ± 7.25 vs. 17.47 ± 5.88, P = 0.421), the Gonadotropin treatment duration (9.53 ± 1.07 vs. 9.67 ± 1.03, P = 0.346) and total Gonadotropin dose (1427.75 ± 210.6 vs. 1455.94 ± 243.44, P = 0.381). GnRH antagonist treatment duration in fixed protocol was statistically longer than the flexible protocol (6.57 ± 1.17 vs 6.04 ± 1.03, P = 0.001). There was no premature LH surge in either protocol.. Fixed GnRH antagonist administration on day 5 of stimulation appear to achieve a comparable oocyte retrieved compared with flexible antagonist administration..

First intention IVF protocol for polycystic ovaries: does oral contraceptive pill pretreatment influence COH outcome?
    Reproductive biology and endocrinology : RB&E, 2013, Jun-19, Volume: 11

    Morphological aspect of polycystic ovaries (PCO) is a very common finding in an IVF center population: this includes PCOS patients identified in 18-25% of the couples presenting with infertility and so called "sonographic PCO only" the prevalence of which has been estimated as high as 33% in asymptomatic patients. Finding the optimal first intention IVF protocol for polycystic ovaries patients is still challenging in order to improve the controlled ovarian hyperstimulation (COH) outcome while avoiding ovarian hyperstimulation syndrome (OHSS). It has been suggested that women with PCO would benefit from a longer period of pituitary down-regulation. The purpose of this study was to compare an extended duration of OCP pretreatment with a classic GnRH agonist protocol.. A single center prospective non-randomized study was performed from January 2009 to December 2010 in the Lille University Hospital including 113 women diagnosed with PCO(S) according to the Rotterdam ultrasonographic criteria and undergoing their first IVF attempt. Comprehensive hormonal and ultra-sonographic assessments were collected during COH in these patients. LH and androgen suppression and dynamics of follicular growth were compared between the two protocols as well as the COH outcome in terms of oocyte/embryo number and quality, implantation and pregnancy rates.. No significant difference was observed between the two groups concerning dynamics of follicular growth and hormonal values. Clinical and ongoing pregnancy rates were significantly lower in the OCP group despite same oocyte and embryo quality. Nevertheless, the cumulative pregnancy rate did not differ between the two groups. The incidence of OHSS was not statistically significant.. Extended duration of OCP pretreatment, as a first intention IVF protocol for PCO patients, does not improve the pattern of follicular growth nor the oocyte and embryo quality.

Flexible GnRH antagonist protocol versus GnRH agonist long protocol in patients with polycystic ovary syndrome treated for IVF: a prospective randomised controlled trial (RCT).
    Human reproduction (Oxford, England), 2010, Volume: 25, Issue:3

    Women with polycystic ovary syndrome (PCOS) are at risk of developing ovarian hyperstimulation syndrome (OHSS) during ovarian stimulation. Use of GnRH antagonist in the general subfertile population is associated with lower incidence of OHSS than agonists and similar probability of live birth but it is unclear if this is true for patients with PCOS. Our aim was to compare the flexible GnRH antagonist and GnRH agonist long protocols in patients with PCOS undergoing IVF (primary end-point: ongoing pregnancy rate per patient randomized).. In this randomised controlled trial (RCT), 220 patients with PCOS were randomly allocated in two groups: long GnRH agonist down-regulation protocol (n = 110) and flexible GnRH antagonist protocol (n = 110).. No differences were observed in ongoing pregnancy rates [50.9 versus 47.3%, difference 3.6%, 95% confidence interval (CI): -9.6 to +16.8%] in the agonist and antagonist protocols, respectively. Incidence of OHSS Grade II was lower in the antagonist compared with agonist group (40.0 versus 60.0%, difference -20.0%, 95% CI: -7.1 to -32.9%, P < 0.01). Duration of stimulation (10 versus 12 days, difference 2 days, 95% CI: +1 to +2, P < 0.001) and total gonadotrophin required (1575 versus 1850 IU, difference -275 IU, 95% CI: -25 to -400, P < 0.05) were also lower in the antagonist compared with agonist protocol.. The current RCT suggests that the flexible GnRH antagonist protocol is associated with a similar ongoing pregnancy rate, lower incidence of OHSS grade II, lower gonadotrophin requirement and shorter duration of stimulation, compared with GnRH agonist. The GnRH antagonist might be the treatment choice for patients with PCOS undergoing IVF. The study was registered at clinicaltrials.gov. ID: NCT00417144.

Serum inhibin A, VEGF and TNFalpha levels after triggering oocyte maturation with GnRH agonist compared with HCG in women with polycystic ovaries undergoing IVF treatment: a prospective randomized trial.
    Human reproduction (Oxford, England), 2006, Volume: 21, Issue:5

    We aimed to examine the serum levels of inhibin A, vascular endothelial growth factor (VEGF), tumour necrosis factor alpha (TNFalpha), estradiol (E2) and progesterone levels after triggering of final oocyte maturation with GnRH agonist compared with HCG in patients with polycystic ovaries (PCO) and to investigate the relationship between these markers and ovarian hyperstimulation syndrome (OHSS).. Twenty-eight patients with PCO, undergoing controlled ovarian hyperstimulation with FSH and GnRH antagonist for IVF-embryo transfer treatment, were randomized for triggering of final oocyte maturation with GnRH agonist (GnRH agonist group, n = 15) or HCG (HCG group, n = 13). Blood samples were obtained on the day of randomization and thereafter every 2-7 days. Serum levels of inhibin A, VEGF, TNFalpha, E2 and progesterone, the incidence of OHSS, ovarian size and pelvic fluid accumulation were evaluated.. Serum inhibin A, E2 and progesterone levels were significantly lower in the GnRH agonist group compared with the HCG group, particularly on the day of embryo transfer (P < 0.0001). Serum VEGF and TNFalpha levels were similar between the two groups. Four patients in the HCG group developed severe OHSS, whereas no patient had any symptoms or signs of OHSS in the GnRH-agonist group (P < 0.05).. In patients with PCO treated with FSH/GnRH antagonist, final oocyte maturation with GnRH agonist instead of HCG reduces significantly inhibin A, E2 and progesterone levels during the luteal phase. This phenomenon reflects the inhibition of the corpus luteum function and may explain, at least in part, the mechanism of OHSS prevention in high-risk patients. Our results do not support a crucial role for VEGF or TNFalpha in OHSS.

Management of women with polycystic ovary syndrome who experienced premature luteinization during clomiphene citrate treatment.
    Fertility and sterility, 2000, Volume: 74, Issue:4

    To determine the preferred treatment modality in patients with PCOS who experienced premature luteinization during CC treatment.. Prospective randomized study.. Tertiary medical center.. Twenty-two infertile women with PCOS demonstrating premature luteinization during at least two consecutive CC cycles.. Randomized induction of ovulation either with FSH alone or with GnRH agonist combined with FSH for a single treatment cycle.. Premature luteinization was defined as serum progesterone >1.5 ng/mL before hCG administration.. Premature luteinization occurred in eight of the 10 patients (80%) in group A and in two of the 12 patients in group B (16.6%). This result corresponds to the higher mean (+/-SD) progesterone level present in group A patients as compared to those in group B (2.0 +/- 1.2 ng/mL vs. 1.2 +/- 0.6 ng/mL, P=0.03). No pregnancies were achieved in group A, whereas the pregnancy rate per cycle observed in group B was 33.3% (4/12). On the day of hCG administration, the maximum mean (+/-SD) estradiol level was significantly lower (P<0.0001) in group A (210.6 +/- 37.9 pg/mL) than in group B (600.3 +/- 253.8 pg/mL). The treatment duration and the number of FSH ampules used did not differ between the groups.. Pituitary desensitization with GnRH analog in combination with FSH is superior to FSH-only treatment in PCOS patients who demonstrate premature luteinization during CC treatment.

Modified dexamethasone and gonadotropin-releasing hormone agonist (Dx-GnRHa) test in the evaluation of androgen source(s) in hirsute women.
    Przeglad lekarski, 2000, Volume: 57, Issue:7-8

    Polycystic ovary syndrome (PCOS) and congenital adrenal hyperplasia (COH) are heterogeneous disorders, in which excess of androgens may be caused by improper function of ovaries and/or adrenals. In many cases an overlap between ovarian and adrenal type of functional hyperandrogenism has been observed. The relationship between adrenal and ovarian metabolism in hyperandrogenic women is not totally known and etiologic diagnosis of female hyperandrogenism is often difficult. The aim of the present study was to evaluate the usefulness of combined Dexamethasone-Triptoreline testing in distinguishing ovarian and adrenal type of functional hyperandrogenism, and checking if the test could be shortened in order to economise it.. We have examined 57 women with androgen excess divided into two groups: ovarian (n = 42) and adrenal (n = 15) and 20 women with idiopathic hirsutism. There was also one patient suffering from Morris syndrome taken under examination just for curiosity. The blood for hormonal assay was taken in baseline conditions at 8.00 a.m. for LH, FSH, PRL, cortisol, T, DHEAS, 17OHP, E2. Dx was given for 4 days 0.5 mg p.o. every 6 hours. 8 hours after the last Dx administration, the blood was taken for 17OHP and T. Immediately after that Triptorelin 100 mg was given s.c. Then the blood was collected every 4 hours during 24 hours for 17OHP estimation.. Decrease in T levels (from 1.65 +/- 0.52 to 0.73 +/- 0.25 ng/ml) after Dexamethasone administration was observed in adrenal group, which indicates adrenal glands as a source of excessive androgen production. No significant differences were seen in ovarian group. But in women from ovarian group supranormal 17OHP response after Triptoreline administration was seen: (ng/ml): at 8.00 am-0.68 +/- 0.44, 12.00--1.21 +/- 0.7*, 16.00--1.71 +/- 1.19*, 20.00--2.39 +/- 1.81*, 24.00--3.41 +/- 2.64*, 4.00--3.91 +/- 2.82*, 8.00--6.06 +/- 2.43* (*p < 0.01, **p < 0.001). Such a response is typical for women with well defined PCOS and other forms of functional ovarian hyperandrogenism and indicates ovary as a source of androgens. Significant differences were also noticed in idiopathic group: 8.00--0.31 +/- 0.09, 12.00--0.38 +/- 0.17, 16.00--1.41 +/- 0.62*, 20.00--1.52 +/- 0.97*, 24.00--1.89 +/- 0.83*, 4.00--2.17 +/- 0.83*, 8.00--1.83 +/- 0.71** (*p < 0.01). 17OHP levels did not change significantly during the whole test in adrenal group: 8.00--1.83 +/- 1.24, 12.00--1.91 +/- 1.37, 16.00--1.95 +/- 0.86, 20.00--2.19 +/- 0.93, 24.00--2.63 +/- 1.58, 4.00--2.56 +/- 1.78, 8.00--237 +/- 0.94. But patients from this group had exaggerated 17OHP response to ACTH (from 4.32 +/- 1.31 to 15.34 +/- 4.1 ng/ml). In patient suffering from Morris syndrome, after Triptoreline, serum 17OHP levels reminded on the same level as they were before drug administration.. Combined Dx-Triptorelin test can be very useful to distinguish ovarian and adrenal type of functional hyperandrogenism. The number of times of blood collection for 17OHP can be reduced to 4 times a day (during 24 hours): at 8.00, 20.00, 24.00, 8.00.

Hormonal and clinical effects of chronic gonadotropin-releasing hormone agonist treatment in polycystic ovary syndrome.
    Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology, 2000, Volume: 14, Issue:5

    The aim of the study was to evaluate the hormonal (focusing on the urinary steroid profile) and clinical effects of chronic gonadotropin-releasing hormone (GnRH) agonist treatment in patients with polycystic ovary syndrome (PCOS) suffering from hirsutism. A long-acting GnRH agonist was administered for 6 months in eight PCOS patients. Hormonal effects were measured by determining serum luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin, testosterone and estradiol concentrations, and by profiling urinary steroids using capillary gas chromatography of 24-hour urine samples. To evaluate 5 alpha-reductase enzyme activity, the ratios of androsterone to etiocholanolone and 5 alpha-tetrahydrocortisol to tetrahydrocortisol were calculated in urine samples. The ratio of androgen to cortisol metabolites was also determined before, and 3 and 6 months after therapy. LH and estradiol levels were suppressed significantly after the first injection and testosterone after the second injection of the GnRH agonist. Thus, serum testosterone was normalized. Ratios of urinary steroids reflecting 5 alpha-reductase enzyme activity (androsterone to etiocholanolone and 5 alpha-tetrahydrocortisol to tetrahydrocortisol) and the ratio of androgen to cortisol metabolites decreased significantly after 3 months of treatment. Degree of hirsutism, assessed by Ferriman-Gallwey score, diminished after 6 months, but not significantly. In conclusion, our data show that long-acting GnRH agonist treatment of PCOS patients is effective in reducing serum and urinary androgen levels, but it is not accompanied by an effective reduction in hirsutism during a 6-month treatment period. A longer or a combined treatment would be needed to achieve significant improvement in hirsutism. Gas chromatographic profiling of urinary steroids and the use of specific ratios of the excreted metabolites seems to be a sensitive tool both in the diagnosis of PCOS and in monitoring ovarian suppression.

Hormonal and clinical effects of GnRH agonist alone, or in combination with a combined oral contraceptive or flutamide in women with severe hirsutism.
    Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology, 2000, Volume: 14, Issue:6

    The objective of this prospective randomized study was to evaluate and compare the hormonal and clinical effects of long-acting gonadotropin-releasing hormone (GnRH) agonist and a combination of GnRH agonist with combined oral contraceptive (COC) or flutamide in women with polycystic ovary syndrome (PCOS). Thirty-five hirsute women with PCOS, ranging in age from 19-27 years, were randomly divided into three groups: group A treated with GnRH agonist (n = 12), group B (n = 12) treated with GnRH agonist plus COC and group C (n = 11) treated with GnRH agonist plus flutamide for 6 months. Before, at the end and 6 months after the end of treatment, blood samples were drawn from all women (in early follicular phase in those with menstrual cycles) to measure ovarian and adrenal androgens, gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH), estradiol and estrone plasma levels. The results showed that all three protocols had good therapeutic efficacy. A significant reduction in hirsutism was observed in all patients after 6 months of therapy, the Ferriman-Gallwey scores dropping to 9 +/- 3 in group A, 10 +/- 4 in group B and 11 +/- 5 in group C. Six months after the end of therapy, the hirsutism score continued to be significantly reduced in all groups. After 6 months of therapy, a reduction in plasma levels of LH, FSH, estrone, estradiol, testosterone, free testosterone, androstenedione and dehydroepiandrosterone sulfate (DHEAS) was observed in all groups although this was more pronounced in group B and group C. These therapies may be the basis of future treatments that quickly reduce hirsutism and remove its causes by reducing the secretion of ovarian and adrenal androgens and by blocking androgen receptors.

Spironolactone, but not flutamide, administration prevents bone loss in hyperandrogenic women treated with gonadotropin-releasing hormone agonist.
    The Journal of clinical endocrinology and metabolism, 1999, Volume: 84, Issue:4

    GnRH agonists (GnRHa) have recently been proposed for the treatment of hirsutism in women with the polycystic ovary syndrome (PCOS). As most of these subjects have increased androgen secretion from both ovaries and adrenal glands, the association of GnRHa with antiandrogen drugs might enhance the clinical response to treatment. On the other hand, this association might also potentiate the adverse effects of GnRHa on bone metabolism, generating a potentially harmful situation at the skeletal level. In this study we investigated in 41 PCOS patients the skeletal effects of a 6-month course of GnRHa (tryptorelin, 3.75 mg, i.m., monthly), either alone (n = 12) or associated with the antiandrogen drugs spironolactone (100 mg, orally, once daily; n = 14) or flutamide (250 mg, once daily; n = 15). In all subjects bone mineral density was measured before and after treatment by dual energy x-ray absorptiometry at the lumbar spine (L2-L4) and at the femoral neck and Ward's triangle. In addition, at baseline and after 6 months of therapy, bone metabolism markers (serum and urinary calcium, serum phosphorus and alkaline phosphatase, plasma osteocalcin, and urinary hydroxyproline) and endocrine parameters (serum gonadotropins, estradiol, and free testosterone) were assayed. Women given either GnRHa alone or associated with spironolactone or flutamide were similar for age and body mass index. At baseline, the 3 groups of PCOS women were also similar for endocrine and bone parameters. After 6 months, all treatments determined similar striking suppressions of serum gonadotropins and sex steroids. Concurrently, bone mineral density was significantly reduced at all examined sites in subjects receiving either GnRHa alone or GnRHa plus flutamide. Conversely, women given GnRHa plus spironolactone did not show any change in skeletal mass from baseline values (P < 0.05-0.01 among groups). Biochemical parameters of bone metabolism were consistent with densitometric assessments. In conclusion, after a 6-month course of therapy, bone mineral density is reduced in PCOS women given either GnRHa alone or GnRHa plus flutamide, but not in those receiving GnRHa plus spironolactone. The mechanisms of the bone-sparing effect of spironolactone remain to be determined. Nevertheless, this drug could represent a useful tool to prevent skeletal loss in women given GnRHa as well as in other hypoestrogenic conditions, in particular when estrogens are not recommended.

Ovarian stimulation with low-dose pure follicle-stimulating hormone in polycystic ovarian syndrome anovulatory patients: effect of long-term pretreatment with gonadotrophin-releasing hormone analogue.
    Gynecologic and obstetric investigation, 1998, Volume: 45, Issue:3

    A randomised clinical trial was performed to evaluate the effect of a 3-month gonadotrophin-releasing-hormone analogue (GnRH-a) in one cycle of ovulation induction with low-dose pure follicle-stimulating hormone (pFSH) in patients with polycystic ovarian syndrome (PCOS) anovulation. Twenty patients with chronic anovulation due to PCOS were randomised to ovulation induction with pFSH administered in a low-dose schedule with (10 patients) and without (10 patients) a 3-month pretreatment with GnRH-a. Ultrasound scan only monitoring of follicular growth, evaluation of plasmatic oestradiol at the day of triggering of ovulation with human chorionic gonadotrophin 5,000 IU and evaluation of plasmatic progesterone 8 days after were the main outcome measures. Ovulation occurred in 9 patients treated with pFSH and in 2 patients treated with GnRH-a plus pFSH. Five pregnancies in the pFSH group and no pregnancy in the GnRH-a group were obtained. Five cycles were stopped due to multifollicular growth in the GnRH-a group and 1 in the pFSH group. Pretreatment with a 3-month administration of a GnRH-a did not improve the ovulation rate and pregnancy rate in PCOS patient ovulation induction with low-dose pFSH.

A long-term treatment with gonadotropin-releasing hormone agonist plus a low-dose oral contraceptive improves the recovery of the ovulatory function in patients with polycystic ovary syndrome.
    Fertility and sterility, 1997, Volume: 67, Issue:3

    To evaluate the hormonal and clinical follow-up after the suspension of a longterm therapy with GnRH-agonist (GnRH-a) plus oral contraceptive (OC) in comparison to OC alone in patients with polycystic ovary syndrome (PCOS).. Hormonal (plasma LH, FSH, sex steroid levels) and clinical (Ferriman-Gallwey score and ultrasound) parameters were monitored at various moments during the 6 months of treatment and during the 6 months after treatment suspension.. Physiopathology of Human Reproduction, University of Modena, Italy.. Thirty patients with PCOS were enrolled and randomly subdivided in two groups of 15 each.. Group A was treated with 3.75 mg IM GnRH-a plus OC. Group B was treated only with OC.. Both therapeutical regimens were effective in reducing androgenic milieu, Ferriman-Gallwey score, and ovarian volume within the 6th month of treatment. However, only patients treated with GnRH-a + OC showed a normal LH:FSH ratio, adequate plasma E2 and P levels, and ovulatory cycles during the 6 months of the after treatment follow-up. Patients treated with OC alone showed no beneficial effect after the 3rd month of the follow-up.. These data support the evidence of a higher efficacy of the combined regimen (GnRH-a + OC) than OC alone in the treatment of patients with PCOS. In addition, the former regimen is associated with recovery of normal ovulatory cycles.

Clinical and hormonal effects of the combination gonadotrophin-releasing hormone agonist plus oral contraceptive pills containing ethinyl-oestradiol (EE) and cyproterone acetate (CPA) versus the EE-CPA pill alone on polycystic ovarian disease-related hype
    Human reproduction (Oxford, England), 1997, Volume: 12, Issue:3

    The aim of this study was to compare the clinical and hormonal effects of the combination of a long-acting gonadotrophin-releasing hormone analogue (GnRH-a) plus an oral contraceptive (OC) pill containing ethinyl-oestradiol (EE) and cyproterone acetate (CPA) versus the EE-CPA pill alone in patients with polycystic ovarian disease (PCOD) and related hyperandrogenisms, in order to evaluate whether the addition of GnRH-a has any advantage. A total of 12 PCOD patients were treated with the EE-CPA pill alone for 10 consecutive cycles according to an OC standard regimen. A further 12 patients were treated with GnRH-a, one i.m. injection every 28 days for a total of eight injections, combined with the EE-CPA pill for 10 consecutive cycles. The latter was thus prolonged for two cycles more than GnRH-a. Clinical evaluations (symptoms, weight, Ferriman-Gallwey score) and hormonal and biochemical analyses were assessed before, during (at 3 or 6 months) and after treatment, either when spontaneous cycles had resumed or after 3 months of amenorrhoea. There was a significant improvement in hirsutism, and a strong reduction in gonadotrophin, oestradiol, testosterone, androstenedione and 17-OH-progesterone concentrations in both treatment groups but with no significant differences between them, except in the gonadotrophin concentrations. Cortisol and triglyceride concentrations increased during treatment in both groups. The Ferriman-Gallwey score remained significantly decreased in both groups after treatment, as did androstenedione in the GnRH-a plus EE-CPA pill group, but there were no significant differences between the two groups. No changes were observed in prolactin, dehydroepiandrosterone sulphate (DHEA-S), insulin, glycaemia and cholesterol concentrations. However, when only the obese and more hirsute patients were considered, significant differences between the two groups were found during treatment in the Ferriman-Gallwey score and the gonadotrophin and DHEA-S concentrations (which increased during treatment in obese patients with the pill alone), and after treatment in the Ferriman-Gallwey score and the concentration of 17-OH-progesterone in the more hirsute patients, with the GnRH-a plus pill group having better results. In conclusion, a cyclic prolonged treatment with OC EE-CPA pills is not improved in most PCOD patients by the addition of GnRH-a, and is complicated and expensive. However, the addition of a long-acting GnRH-a may be recommended in obese and

Intermittent Etidronate partially prevents bone loss in hirsute hyperandrogenic women treated with GnRH agonist.
    Osteoporosis international : a journal established as result of cooperation between the European Foundation for Osteoporosis and the National Osteoporosis Foundation of the USA, 1997, Volume: 7, Issue:2

    Treatment with gonadotropin-releasing hormone (GnRH) agonist leads to enhanced bone turnover and accelerated bone loss in premenopausal women with endometriosis, uterine leiomyomatomas and hirsutism. Sodium etidronate is a powerful inhibitor of bone resorption which had been proven efficacious in the prevention and treatment of postmenopausal osteoporosis. The objective of this study was to evaluate the skeletal effects of 6 months of therapy with the depot preparation of the GnRH agonist triptorelin (decapeptil 3.75 mg intramuscularly every 4 weeks) in 24 hirsute patients, aged 24-33 years, with hyperandrogenic chronic anovulation. Ten patients also received cyclical etidronate in an oral dose of 400 mg/day for 2 weeks, followed by an 11-week period of 500 mg/day elemental oral calcium (one cycle). The remaining 14 patients received 500 mg/day of elemental calcium continuously. After 6 months all treatments were discontinued for at least a further 6 months. Bone mineral density (BMD) at lumbar spine and hip (dual-energy X-ray absorptiometry, Sophos LXRA, France) and biochemical markers (serum alkaline phosphatase, osteocalcin, urinary N-telopeptide and hydroxyproline/creatinine ratio) were evaluated at baseline, 6 months and 12 months. In the group given GnRH agonist alone BMD fell significantly at all measured skeletal sites during the first 6 months. In the patients treated with etidronate a significant decrease in BMD was observed at lumbar spine but not in the femoral neck and trochanter, and the changes at lumbar spine and trochanter were significantly smaller than those in the control group. At 6 months bone turnover was also increased in patients treated with GnRH and calcium. Cyclical etidronate prevented the increase in biochemical markers of bone formation and resorption, with the exception of calcium/creatinine excretion, which was significantly increased in both groups. Six months after treatment withdrawal BMD did not recover in either group. Biochemical markers (N-telopeptide, serum alkaline phosphatase) remained increased in those patients previously treated with calcium alone while they remained close to baseline values in the patients treated with cyclical etidronate. Our study indicates that: (1) GnRH agonist therapy causes remarkable bone loss in young individuals with androgen excess who are expected to have increased bone mass; (2) this bone loss can be partially prevented by intermittent cyclical etidronate therapy.

The importance of endogenous feedback for monofollicular growth in low-dose step-up ovulation induction with follicle-stimulating hormone in polycystic ovary syndrome: a randomized study.
    Fertility and sterility, 1996, Volume: 66, Issue:4

    To evaluate the role of endogenous feedback in monofollicular growth during low-dose gonadotrophin therapy in polycystic ovary syndrome (PCOS) by measuring FSH levels in a group of patients cotreated with a GnRH agonist (GnRH-a) (group B) compared with patients not cotreated with an agonist (group A).. Prospective randomized study.. University tertiary care Reproductive Endocrinology Unit.. Women with clomiphene citrate-resistant PCOS.. Follicle-stimulating hormone, E2, and inhibin levels, follicular growth.. In group A, FSH levels decreased significantly from 7.3 mIU/mL (conversion factor to SI unit, 1.00) at day -5 to 5.9 mIU/mL at day 0 (day that hCG was administered) despite a constant dose, whereas they remained at a level of 7.4 mIU/mL in group B. The rate of monofollicular growth was significantly higher in group A (80%) than in group B (22%). No significant differences in E2 levels or inhibin levels were found between the groups.. The absence of a decrease of FSH during GnRH-a treatment in association with a lower rate of monofollicular growth suggests that endogenous feedback during low-dose step-up ovulation induction in PCOS plays an important role. The absence of this feedback mechanism in the presence of normal inhibin levels suggests that negative feedback control by inhibin during follicular stimulation is minimal.

Polycystic ovary syndrome patients as oocyte donors: the effect of ovarian stimulation protocol on the implantation rate of the recipient.
    Fertility and sterility, 1995, Volume: 64, Issue:3

    To evaluate the outcome of oocytes donated by women with polycystic ovarian syndrome (PCOS) compared with oocytes donated by women with mechanical infertility.. A retrospective study.. The outcome of 159 oocyte donation cycles with oocyte donated by PCOS patients were compared with 69 oocyte donation cycles with oocytes donated by patients with mechanical infertility. We compared the stimulation protocols in the donors to assess if the combination of GnRH analogue (GnRH-a), FSH, and hMG has an advantage over FSH and hMG alone with respect to their effect on fertilization and implantation rates in oocyte donation cycles.. When treated with GnRH-a, pregnancy rates in PCOS and mechanical infertility donors were higher than those treated with FSH and hMG alone. The comparison between PCOS and mechanical factor oocyte recipients revealed no significant difference in the pregnancy and abortion rates, but the oocytes of patients with PCOS that were exposed to GnRH-a had a significantly higher implantation rate than those not exposed to GnRH-a.. Oocytes obtained from PCOS patients had a fertilization potential equal to oocytes obtained from mechanical infertility donors. Furthermore, because the oocytes of patients with PCOS exposed to GnRH-a had a significantly higher implantation rate, a detrimental role of high LH on oocyte quality seems probable. However, because PCOS has a high familial prevalence, some reservations may arise due to a possible propagation of the problem in the next generation of oocyte donation programs.

    Determine whether ovulation in dystrophic ovaries treated with GnRH agonist followed by GnRH pulses is due to the GnRH pulse or is patient-dependent. SITE. Endocrinology department, CHU Purpan, Toulouse, France.. Fifteen infertile patients, age range 22 to 35 years, with ovarian dystrophy were given GnRH agonist (Decapeptyl, 3.75 mg IM on day 3 of the cycle). In 5 patients, an IV pulse of GnRH was then given (6 micrograms/90 min).. Mann-Whitney U test, corrected chi 2 test.. Ovulation was achieved in 8/15 cases (3/5 with and 5/10 without pulsatile GnRH p = NS) and 3 pregnancies (without pulsatile GnRH). Before treatment LH was higher in patients who had an ovulation.. Ovulation can be achieved after GnRH agonist treatment in patients with dystrophic ovaries, with or without pulsatile GnRH, particularly if the initial LH levels are high.

Adjuvant growth hormone for induction of ovulation with gonadotrophin-releasing hormone agonist and gonadotrophins in polycystic ovary syndrome: a randomized, double-blind, placebo controlled trial.
    Human reproduction (Oxford, England), 1995, Volume: 10, Issue:10

    The objective of this study was to explore the effect of cotreatment with recombinant human growth hormone (GH), gonadotrophin-releasing hormone agonist (GnRHa) and human menopausal gonadotrophin (HMG) for induction of ovulation in women with clomiphene resistant polycystic ovary syndrome (PCOS). It was designed as a randomized, double-blind, placebo controlled trial in which 30 women with anovulation associated with PCOS who were resistant to clomiphene all received DTRP6-LHRH (Decapeptyl microcapsules, 3.75 mg, i.m.) and, 2 weeks later, HMG in a standard, conventional, individually adjusted dose regimen until human chorionic gonadotrophin (HCG) and then luteal phase support could be given. From day 1 of HMG therapy, patients were randomized to receive either human GH (Norditropin, 12 IU/day, i.m., for 7 days) or placebo. The number of ampoules, duration of treatment and daily effective dose of HMG required to achieve ovulation, serum oestradiol concentrations and number of follicles induced, ovulation and pregnancy rates, serum insulin and insulin-like growth factor-I (IGF-I) concentrations were measured. There were no significant differences between growth hormone and placebo groups in any of the outcomes measured, other than a growth hormone induced increase in serum insulin and IGF-I levels. We conclude that although GH kinetics are abnormal and GH pituitary reserves generally low in women with PCOS, adjuvant GH treatment to GnRHa/HMG does not influence follicular development or sensitivity in response to gonadotrophins and that it does not seem likely to be of any potential clinical benefit for the treatment of PCOS.

The role of insulin in ovarian size in patients with the polycystic ovary syndrome.
    Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology, 1994, Volume: 8, Issue:3

    The objective of this study was to evaluate whether the degree of suppression of ovarian volume effected by a gonadotropin releasing hormone (GnRH) agonist in patients with polycystic ovary syndrome (PCOS) correlated with basal insulin secretion and insulin secretion provoked by a glucose challenge. Eighteen PCOS patients received the GnRH agonist D-tryptophan-6-LHRH (Decapeptyl, 3.75 mg monthly i.m.) for 6 months and had blood glucose and insulin measured during a 75 g oral glucose tolerance test (OGTT) prior to and at the end of therapy. According to ovarian volume suppression after GnRH agonist therapy, two groups were defined: in group A (n = 10; mean body mass index (BMI) +/- SEM, 25.6 +/- 1.6 kg/m2) ovarian volume regressed from 17.9 +/- 1.6 to 6.7 +/- 0.3 ml (full responders) and in group B (n = 8; mean BMI +/- SEM, 28.1 +/- 2.3 kg/m2) from 21.5 +/- 1.1 to 15.1 +/- 1.0 ml (partial responders). Results showed that GnRH agonist therapy did not affect significantly BMI or fasting levels and area under the curve (AUC) for glucose and insulin in the respective groups. Fasting insulin levels correlated positively with ovarian volume prior to (r = 0.56, p < 0.05) and after 6 months of GnRH agonist therapy (r = 0.80, p < 0.005). The suppressibility of ovarian volume with GnRH agonist therapy correlated negatively with the difference between maximal and basal levels (r = -0.68), the area under the curve (r = -0.62) and maximal levels (r = -0.72) for insulin during the OGTT.(ABSTRACT TRUNCATED AT 250 WORDS)

Efficacy of chronic therapy with the gonadotrophin releasing hormone agonist decapeptyl in patients with polycystic ovary syndrome.
    Human reproduction (Oxford, England), 1994, Volume: 9, Issue:6

    Our objective was to assess the endocrine and morphological response of polycystic ovary syndrome (PCOS) in patients receiving 6 months of therapy with the long-acting gonadotrophin releasing hormone agonist (GnRH agonist) decapeptyl (3.75 mg monthly injections). Eighteen documented PCOS patients were basally evaluated for hirsutism, gonadotrophin and androgen concentrations and ovarian morphology using trans-vaginal ultrasonography. Measurements were repeated at 3 and 6 months. The results (values as mean +/- SD) showed a significant improvement in hirsutism (Ferriman score 11.0 +/- 5.9 versus 6.6 +/- 2.7, P < 0.01), acne and seborrhoea. A significant post-treatment decrease in gonadotrophins [follicle-stimulating hormone (FSH): 5.8 +/- 1.8 versus 3.8 +/- 1.1 IU/l, P < 0.01; luteinizing hormone (LH): 10.8 +/- 8.3 versus 3.4 +/- 3.3 IU/l, P < 0.01], LH/FSH ratio (1.8 +/- 1.1 versus 0.8 +/- 0.6, P < 0.01) and androgen concentrations (free testosterone: 4.0 +/- 1.9 versus 1.9 +/- 0.7 pg/ml, P < 0.01, delta 4-androstenedione: 3.9 +/- 1.2 versus 1.9 +/- 0.6 ng/ml, P < 0.001) was also found, while oestradiol approximated castration concentrations (68.4 +/- 29.5 versus 29.1 +/- 6.7 pg/ml, P < 0.001). Finally, mean ovarian volume (19.7 +/- 6.2 versus 10.9 +/- 4.6 cm3, P < 0.001), capsule thickness (2.5 +/- 0.8 versus 1.9 +/- 0.7 mm, P < 0.05) and stromal density dropped significantly, as did uterine volume (34.2 +/- 10.5 versus 19.9 +/- 8.9 cm3, P < 0.01). In conclusion, treatment of our PCOS patients for 6 months with the GnRH agonist decapeptyl proved efficient in inducing significant clinical, biochemical and ovarian morphological improvement.

    The study evaluates the efficacy of tryptorelin treatment in cases of acne and hirsutism associated with polycystic ovarian (PCO) disease. This non-comparative open study in a sample population of 20 young patients who wished to have children demonstrates the reduction of the hirsutism and acne score after six months' treatment. Tryptorelin was even capable of normalizing the hematic hormonal levels examined and ovarian function following six months of treatment, as well as at an initial follow-up after three months. The authors state their intention of performing a larger trial in order to observe the real efficacy of tryptorelin in a study which includes a 12-month follow-up to assess the pregnancy rate.

Treatment of polycystic ovarian disease during adolescence with ethinylestradiol/cyproterone acetate versus a D-Tr-6-LHRH analog.
    International journal of gynaecology and obstetrics: the official organ of the International Federation of Gynaecology and Obstetrics, 1993, Volume: 42, Issue:2

    This study was undertaken to compare the clinical and endocrinological results of two kinds of treatment on adolescents with polycystic ovarian disease (PCOD).. Forty-five adolescents with PCOD were randomly allocated into two groups, treated either with ethinylestradiol (EE)/cyproterone acetate (group A) or the GnRH analog D-Tr-6-LHRH (group B).. No significant changes were detected on the body mass index and waist-hip circumference. A significant improvement of hirsutism was noticed in both groups of patients. A normal menstrual period was recorded in group A adolescents while all group B patients became amenorrheic. A favorable decrease of ovarian volume was detected in both groups. LH/FSH ratio and delta 4-androstenedione serum levels were found significantly reduced in both groups in comparison to pre-treatment levels. The comparison between the two groups, after 6 months, showed significantly lower values of LH/FSH ratio in group B cases.. Both forms of treatment are safe and effective to a various degree for the management of PCOD adolescents.

The choice of treatment for anovulation associated with polycystic ovary syndrome following failure to conceive with clomiphene.
    Human reproduction (Oxford, England), 1993, Volume: 8, Issue:9

    The choice of treatment for clomiphene-resistant anovulation associated with polycystic ovary syndrome (PCOS) is presently arbitrary and selection criteria are not available. A total of 144 women with anovulatory infertility associated with PCOS who failed to conceive on clomiphene were treated with either pure follicle stimulating hormone (FSH) (n = 29), or human menopausal gonadotrophin (HMG) (n = 60), or gonadotrophin-releasing hormone analogue (GnRHa) and HMG (n = 55). Analysis of 306 treatment cycles and 53 pregnancies revealed a cumulative conception rate at 4 months of 23% with FSH, 47% with HMG and 69% with GnRHa + HMG. The miscarriage rate was highest in the HMG group (44%) and consequently the cumulative live birth rate was superior when GnRHa was used in combination with HMG. There were no significant differences in the basal clinical and endocrinological features of those who conceived compared with those who did not, either in the whole group, or in the individual treatment groups. Thus, the choice of treatment for clomiphene-resistant women with PCOS cannot be guided by the basal clinical or endocrinological features of this heterogeneous syndrome with the present state or knowledge.

Cytokine levels in follicular fluid of polycystic ovaries in patients treated with dexamethasone.
    Fertility and sterility, 1992, Volume: 57, Issue:3

    To assess the levels of cytokines in the follicular fluid of stimulated ovaries.. The study included two groups of four patients with polycystic ovarian disease. These were diagnosed by clinical and ultrasonic features and characteristic hormonal profiles, treated with gonadotropin-releasing hormone-analogue and human menopausal gonadotropin. One group received dexamethasone (DEX).. Dexamethasone is capable of directly affecting granulosa and immune cells. It was also expected to affect cytokine production of granulosa and immune cells of the ovary.. This study demonstrates that FF from patients treated with DEX has reduced tumor necrosis factor (TNF) activity and elevated colony-stimulating factor levels. Regardless of the treatment with DEX, the follicles with high levels of TNF contained minimal concentrations of estradiol. Interleukin-6 did not differ between the FF samples.. These results suggest a role for cytokines in the process of folliculogenesis and ovarian maturation. Modification of cytokines by DEX might explain the beneficial effect of fertility.

Comparative effects of cyproterone acetate or a long-acting LHRH agonist in polycystic ovarian disease.
    Hormone research, 1987, Volume: 28, Issue:2-4

    A randomized cross-over study was done to compare the therapeutic efficacy of cyproterone acetate (CPA, 50 mg/day orally) and a depot preparation of the LHRH superagonist (D-Trp6 LHRH 3 mg i.m. once a month) in 10 patients with polycystic ovarian disease (PCO). The two treatment periods were separated by 6 months. Both treatments resulted in marked clinical improvement. In response to CPA treatment, basal plasma gonadotropin, estradiol, estrone, testosterone and androstenedione levels significantly decreased. In response to D-Trp6 LHRH, both basal and stimulated gonadotropin levels were completely suppressed after 3 weeks of treatment. After initial elevation on day 2, plasma ovarian steroid levels fell into the castrate range, without any change in dehydroepiandrosterone sulfate levels. Urinary 3 alpha-androstanediol excretion decreased significantly. In patients with PCO, LHRH-A induced more complete gonadotropin inhibition than did CPA. However, following cessation of either therapy, the disease rapidly recurred.

Comparative effects of cyproterone acetate or a long-acting gonadotropin-releasing hormone agonist in polycystic ovarian disease.
    The Journal of clinical endocrinology and metabolism, 1986, Volume: 63, Issue:4

    A randomized cross-over study was done to compare the therapeutic efficacy of cyproterone acetate (CPA) and a depot preparation of the LHRH superagonist (DTrp6-LHRH) in 10 patients with polycystic ovarian disease (PCO). All patients were treated with both agents (50 mg/day CPA, orally and (3 mg DTrp6-LHRH, im, approximately once a month) for 3 months, the 2 treatment periods being separated by 6 months. Both treatments resulted in marked clinical improvement, with diminished acne and seborrhoea and normalization of ovarian size by ultrasonographic criteria. In response to CPA treatment, basal plasma gonadotropin levels decreased, but the response to a LHRH test was not completely suppressed. Plasma estradiol, estrone, testosterone, and androstenedione levels significantly decreased, but urinary 3 alpha-androstanediol and plasma dehydroepiandrosterone sulfate levels did not change significantly. In contrast to CPA treatment, both basal and stimulated gonadotropin levels were completely suppressed after 3 weeks of treatment with DTrp6-LHRH. After a slight initial evaluation on day 2, plasma estrogen and androgen levels, with the exception of dehydroepiandrosterone sulfate fell into the castrate range urinary 3 alpha-androstanediol excretion decreased significantly. Thus, in patients with PCO, LHRH-A induced more complete gonadotropin inhibition than did CPA. After cessation of either therapy, the disease rapidly recurred.

What is the best treatment for women with polycystic ovarian syndrome and high LH/FSH ratio? A comparison among in vitro fertilization with GnRH agonist, GnRH antagonist and in vitro maturation.
    Journal of endocrinological investigation, 2016, Volume: 39, Issue:7

    To evaluate whether high LH/FSH ratio has a clinical impact on patients with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization (IVF) with GnRH-agonist/antagonist protocols or in vitro maturation (IVM) treatments.. We retrospectively reviewed all PCOS patients with day 3 LH/FSH ratio ≥1.5 who underwent IVF or IVM. The main outcomes measures were embryo quality and pregnancy rate.. A total of 75 cycles were included. Among these, 44 patients underwent long agonist protocol, 16 antagonist protocol and 15 IVM. Age, basal LH and FSH levels, as well as duration of infertility were comparable for all groups. The LH level on the day of hCG administration was significantly lower in the antagonist group (0.9 IU/ml) compared to the long agonist group (1.4 IU/ml, p = 0.01). There was no difference in pregnancy rates among the groups: 27.2 % in the long agonist group, 37.5 % in the antagonist group and 26.6 % among the IVM patients.. High LH/FSH ratio had no adverse effect on pregnancy rates in all three treatment modes.

Ovulation induction and luteal support with GnRH agonist in patients at high risk for hyperstimulation syndrome.
    Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology, 2015, Volume: 31, Issue:9

    The aim of this study was to compare GnRHa trigger and luteal addition of triptorelin to hCG trigger for final oocyte maturation in women at high risk for OHSS undergoing IVF. A total of 423 patients were divided in two groups both stimulated using antagonist short protocol. Gonadotropins 75-150 UI/day were started on day 2-5, GnRH antagonist was added when the lead follicle was >14 mm and the final trigger was obtained with hCG 250 µg or triptorelin 0.2 mg. The luteal phase was supported with progesterone alone in the hCG group, with progesterone plus triptorelin 0.1 every other day from embryo transfer in the triptorelin group. In the triptorelin group we did neither have to suspend any embryo transfer, nor we have any early clinical OHSS. In the control group, 13 patients were suspended due to symptomatic high risk for OHSS and two patients developed a clinically significant OHSS. No statistically significant difference was observed in terms of clinical and ongoing pregnancy rates and implantation rates. Our results indicate that a protocol including GnRHa as trigger and an intensive luteal phase supported with GnRHa is safer than a standard antagonist protocol using hCG as trigger. It displays similar results, therefore it can be used as the first choice in patients at high risk for OHSS.

A novel modified ultra-long agonist protocol improves the outcome of high body mass index women with polycystic ovary syndrome undergoing IVF/ICSI.
    Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology, 2014, Volume: 30, Issue:3

    In an attempt to evaluate the effectiveness of a novel modified ultra-long agonist (ULA) protocol on polycystic ovary syndrome (PCOS) patients undergoing in vitro fertilisation (IVF)/intracytoplasmic sperm injection (ICSI), a retrospective study of 499 women employed with either ULA or conventional long agonist (LA) protocol was analyzed. In high BMI group (>25 kg/m²), the ULA protocol yielded significant higher clinic pregnancy rate (PR) (70.2% versus 50.8%, p < 0.05), implantation rate (52.7% versus 35.7%, p < 0.05) and live birth rate (63.8% versus 39.0%, p < 0.05) when compared with LA protocol. In low BMI group (≤25 kg/m²), the ULA protocol also demonstrated a higher clinic PR (70.8% versus 59.5%, p < 0.05) whereas implantation rate and live birth rate are comparable. Within ULA protocol, the clinic PR, implantation rate and live birth rate are similar between high and low BMI patients. Similarly, the clinic PR and live birth rate demonstrated no significant difference within LA group but there is a significant lower implantation rate (35.7% versus 63.9%, p < 0.05) observed in high BMI patients. No difference in miscarriage rate and severe OHSS rate was found among all groups. In conclusion, ULA protocol benefits the IVF outcomes of PCOS patients with high BMI status.

What is the preferred GnRH analogue for polycystic ovary syndrome patients undergoing controlled ovarian hyperstimulation for in vitro fertilization?
    Fertility and sterility, 2009, Volume: 91, Issue:4 Suppl

    In an attempt to evaluate the influence of the GnRH analogue used during controlled ovarian hyperstimulation (COH) on the outcome of IVF cycles of polycystic ovary syndrome (PCOS) patients, we studied 152 IVF cycles. The PCOS patients undergoing COH using the GnRH agonist protocol (n = 50) showed a significantly higher pregnancy rate (36% vs. 19.6%, respectively), compared with the GnRH antagonist protocol (n = 102).

Does plasma insulin level affect ovarian response to exogenous administration of follicle-stimulating hormone in women without polycystic ovary syndrome?
    Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology, 2005, Volume: 21, Issue:5

    Raised insulin levels have been shown to contribute to ovarian overproduction of androgens. Hyperinsulinemia, usually associated with polycystic ovary syndrome (PCOS), brings about greater ovarian endocrine and morphological responses to ovulation induced by follicle-stimulating hormone (FSH). This indicates that elevated levels of insulin play a role in the endocrine and paracrine control of the ovaries.. The aim of the present study was to investigate whether basal insulin levels influence ovarian response to FSH in healthy women (non-PCOS) undergoing assisted reproduction by in vitro fertilization-embryo transfer (IVF-ET).. The study included 36 consecutive women, 27-45 years old, undergoing IVF-ET for tubal-factor or male-factor infertility. Serum insulin levels were determined on the day of administration of gonadotropin-releasing hormone analog (GnRHa) and on the first day of FSH administration.. Mean insulin levels were 6 +/- 3 and 7 +/- 3 microU/ml on the day of GnRHa and FSH administration, respectively. No correlations were found between basal insulin level, days of treatment, total FSH dose, estradiol level and the number of oocytes retrieved.. The results of the present study show that normal levels of insulin do not seem to influence ovarian response to FSH in non-PCOS women. In all patients included in our study, serum insulin levels did not correlate with IVF stimulation data (days of stimulation, total FSH dose) nor with IVF-ET outcome. Thus the study demonstrates that, in patients who are not insulin-resistant, insulin does not correlate with ovarian response to FSH administration.

The behavior of follicle cysts formed after long-acting gonadotropin-releasing hormone analog administration in patients with polycystic ovarian syndrome.
    Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology, 1997, Volume: 11, Issue:2

    This study was conducted to examine the effect of ovarian cysts that develop after administration of a gonadotropin-releasing hormone (GnRH) analog during an ovulation induction program for patients with polycystic ovarian syndrome. Twenty-eight women received Decapeptyl Continuous Release for 70 cycles starting on day 3 of the menstrual cycle, after exclusion of any ovarian pathology by transvaginal ultrasonography. Fifteen days later ultrasonography was again performed and serum estradiol estimated. Cystic structures > or = 20 mm in the ovaries were defined as follicle cysts. In three cycles follicle cysts developed and low estradiol levels were measured (Group 1). In another six cycles cysts developed after GnRH analog, and elevated estradiol levels were found (Group 2). In the latter, estradiol decreased 3 to 7 days later, with cyst regression in three cases. Ovulation induction with human menopausal gonadotropin (hMG) was initiated only if the estradiol level was < or = 20 pg/ml, otherwise induction was postponed until estradiol decreased, disregarding the presence of cysts. When 2 to 3 follicles were > or = 18 mm, and generally when estradiol levels were < 1500 pg/ml, human chorionic gonadotropin was administered. All the cycles were ovulatory and two women from Group 2 conceived. The development of follicle cysts with low serum estradiol levels after GnRH analog administration represents a benign condition and is not a contraindication for hMG stimulation. In cases with elevated estradiol levels, ovulation induction can be postponed until the estradiol has decreased. Our study revealed good ovulatory and pregnancy rates as a result.

Effects of ovary suppression by a long-acting GnRH-agonist on circulating GH, insulin-like growth factor I and insulin levels in women with polycystic ovary syndrome.
    Journal of endocrinological investigation, 1997, Volume: 20, Issue:4

    Our aim was to investigate the effect of GnRH-agonist (GnRH-a) induced suppression of plasma sex steroids on serum GH, insulin like growth factor-I (IGF-I) and insulin levels after an oral glucose load (OGTT) in women with polycystic ovary syndrome (PCOS). Serum insulin, GH and IGF-I levels during a 75-g 4-h OGTT were measured in 3 nonobese and 7 obese hyperandrogenic women with PCOS and normal glucose tolerance before and after 10 weeks of treatment with the GnRH-a triptorelin (3,75 mg im every 28 days). Basal estrogen and androgen levels were also measured at time 0 of the first and the second OGTT. After the therapy serum estrogens and androgens were significantly suppressed. Body weight remained unchanged. Basal GH significantly increased after the treatment while fasting IGF-I and insulin levels decreased from (mean +/- SE) 349.3 +/- 31.8 to 278.7 +/- 33.2 ng/mL and from 22.4 +/- 4.1 to 18.8 +/- 4.4 microU/mL, respectively. The insulin response to OGTT (area under curve) was also reduced (from 16,017 +/- 2598 to 11,736 +/- 2317 microU/mL/240 min). Our results suggest that the GnRH-a induced suppression of ovary secretion may modify the serum GH and IGF-I levels and the insulin response to an OGTT in women with PCOS.

The outcome of an in vitro fertilization program in women with polycystic ovary syndrome.
    Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology, 1997, Volume: 11, Issue:4

    The objective of this study was to examine the efficacy of D-triptorelin in the long protocol and follicle-stimulating hormone (FSH) in an IVF-embryo transfer program in a group of patients with polycystic ovary syndrome (PCOS) who had earlier failed to respond or did not conceive after clomiphene citrate (CC)/human menopausal gonadotropin (hMG) or 'flare up' gonadotropin-releasing hormone agonist (GnRHa)/hMG stimulation. Eighty-nine women with PCOS (based on typical ultrasound criteria) had 1-3 treatment cycles without success. The stimulation protocol was changed to D-triptorelin given in midluteal phase and when pituitary desensitization was achieved, FSH administration was started. The clinical pregnancy rate per transfer in this 'negatively selected' group of PCOS patients was 29%. This was the same as the rate for a group of women with tubal factor, as was the spontaneous miscarriage rate. Although the use of GnRH agonists in the long protocol increases the costs of treatment, the number of cancelled cycles is reduced. The pregnancy rate increased in this group of women with PCOS.

    Zhonghua fu chan ke za zhi, 1996, Volume: 31, Issue:5

    To investigate the efficacy of the treatment for polycystic ovary syndrome (PCOS) patients by combined long acting gonadotropin-releasing hormone agonist (GnRHa) and gonadotropin.. Nineteen women with PCOS who had failed to conceive on treatment with conventional fertilization in vitro-embryo transfer (IVF-ET) protocol underwent 26 cycles of IVF-ET by combined long-acting and gonadotropin stimulation. A self-control group consisted of 19 PCOS women who had received 19 treatment cycles with conventional IVF-ET stimulation protocol more than 6 months previously.. A comparison of these two groups showed that treatment with combined long-acting GnRHa and gonadotropin improved the in vitro fertility rate (76.2%) and pregnancy rate (38.5%).. Patients with refractory PCOS should be referred for IVF-ET, using long-acting GnRHa before gonadotropin as the stimulation protocol.

Polycystic ovarian syndrome: pregnancy outcome following in vitro fertilization-embryo transfer.
    Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology, 1995, Volume: 9, Issue:2

    A retrospective study of a series of pregnant patients with polycystic ovarian syndrome following in vitro fertilization-embryo transfer was conducted to assess the outcome after ovarian stimulation by different protocols. Forty-one pregnancies were evaluated in patients with polycystic ovarian syndrome who conceived during in vitro fertilization-embryo transfer using human menopausal gonadotropin alone (17 pregnancies), or combined with gonadotropin releasing hormone analog (24 pregnancies). The demographic data of in vitro fertilization-embryo transfer cycles and pregnancy outcome were compared with the use of Student's t-test, the Mann-Whitney U test and Fisher's exact test, where appropriate. Among the pregnancies that were initiated following treatment, the protocol of the combination of the two was not associated with a higher rate of deliveries. The rate of first-trimester abortions was not statistically different between the two groups. These results suggest that the combined use of gonadotropin releasing hormone agonist and human menopausal gonadotropin in an in vitro fertilization program may not have beneficial effects on pregnancy outcome in patients with polycystic ovarian syndrome.

Reassessment of adrenal androgen secretion in women with polycystic ovary syndrome.
    Obstetrics and gynecology, 1995, Volume: 85, Issue:6

    To reevaluate the clinical significance of elevations of adrenal androgens in polycystic ovary syndrome (PCOS).. Thirty women with PCOS and ten ovulatory controls were evaluated. Serum dehydroepiandrosterone (DHEA) sulfate and 11 beta-hydroxyandrostenedione were measured before and after 3 and 6 months of GnRH agonist (GnRH-A) therapy. All controls and 15 women with PCOS received intravenous ACTH before and after GnRH-A therapy.. Twenty-one (70%) of the women with PCOS had elevations of DHEA sulfate, and 16 (53%) had elevations in 11 beta-hydroxyandrostenedione. Only two women with PCOS had normal values of both adrenal androgens. After GnRH-A therapy, only 11 subjects (37%) had elevated values of DHEA sulfate. Four of 16 women had reductions in 11 beta-hydroxyandrostenedione. Only those with elevated baseline DHEA sulfate levels had reductions after GnRH-A therapy. The reduction of DHEA sulfate with GnRH-A correlated with the reduction in androstenedione. Of the subjects who had reductions in DHEA sulfate with GnRH-A therapy, there was a blunted response of DHEA to ACTH after treatment.. Our findings suggest that the ovary may influence the prevalence and magnitude of adrenal androgen excess in PCOS.

Time-dependent changes in serum 3 alpha-androstanediol glucuronide correlate with hirsutism scores after ovarian suppression.
    Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology, 1995, Volume: 9, Issue:3

    The clinical utility of serum 3 alpha-androstanediol glucuronide level has been controversial. Among the concerns regarding its lack of utility has been the finding that suppression of serum 3 alpha-androstanediol glucuronide does not occur readily with treatment. We hypothesized that because the treatment of hirsutism requires a prolonged duration, a longer observation period is required for changes in serum 3 alpha-androstanediol glucuronide to be measured. Therefore, we studied the clinical and hormonal changes in 11 women treated for hirsutism with a gonadotropin-releasing hormone agonist (GnRH-a) for 1 year. A progressive reduction in Ferriman-Gallwey scores occurred, which was significant at 6 weeks and was maximal at 12 months. Serum 3 alpha-androstanediol glucuronide and another peripheral marker, androsterone glucuronide, also fell commensurately. While there was no correlation at 3 months, by 6 weeks a significant correlation had occurred between the suppression in Ferriman-Gallwey scores and the suppression of serum 3 alpha-androstanediol glucuronide and androsterone glucuronide. The suppression of these steroids also correlated with the suppression of non-sex hormone-binding globulin-bound testosterone. These data confirm that markers of peripheral androgen action, particularly serum 3 alpha-androstanediol glucuronide, reflect the clinical manifestation of hirsutism. However, it appears that modifications in peripheral androgen activity (presumably through 5 alpha-reductase activity) are time-dependent, and that serum markers reflect changes after 6 months of treatment.

Ovarian suppression with triptorelin and adrenal stimulation with adrenocorticotropin in functional hyperadrogenism: role of adrenal and ovarian cytochrome P450c17 alpha.
    Fertility and sterility, 1994, Volume: 62, Issue:3

    To validate combined ovarian suppression with triptorelin and adrenal stimulation with ACTH in the diagnosis of female hyperandrogenism and to provide new insights into the adrenal-ovarian relationship present in this disorder.. Comparison of sexual steroids and basal and ACTH-stimulated steroid levels before and after ovarian suppression induced by triptorelin.. Department of Endocrinology, Hospital Ramón y Cajal, Madrid, Spain.. Thirty-nine nonselected women with hyperandrogenism.. Serum levels of T, 17-hydroxyprogesterone (17-OHP), 17-hydroxy-pregnenolone, DHEA and DHEAS, androstenedione (delta 4-A), 11-deoxycortisol, and cortisol.. Elevated T independent of ovarian suppression pointed to an adrenal disorder in six patients (one with an androgen-producing adenoma, two with late-onset 21-hydroxylase deficiency, three with functional adrenal hyperandrogenism). Nineteen patients had functional ovarian hyperandrogenism as elevated T normalized after ovarian suppression and were subdivided into ovDHEAS+ (n = 7) and ovDHEAS = (n = 12) subgroups depending on the presence of DHEAS hypersecretion. Finally, 14 patients had idiopathic hirsutism according to normal T before and after ovarian suppression. Comparisons of initial hormonal values between groups and with reference values obtained from normal women (n = 11) disclosed in functional adrenal hyperandrogenism an elevation of T and basal and stimulated DHEAS, delta 4-A, and 17-OHP with respect to normal women. These abnormalities were also present in ovDHEAS+ except for basal delta 4-A, which was normal, whereas only T and stimulated 17-OHP were elevated in ovDHEAS =. In the idiopathic group all steroids were normal with the exception of a mild elevation in stimulated DHEAS.. These results show a continuum of abnormalities in hyperandrogenic women, suggesting an enhanced cytochrome P450c17 alpha activity in the adrenal and the ovary as the shared mechanism between functional adrenal hyperandrogenism and functional ovarian hyperandrogenism.

Gonadotropin-releasing hormone agonist reduces the miscarriage rate for pregnancies achieved in women with polycystic ovarian syndrome.
    Fertility and sterility, 1993, Volume: 59, Issue:3

    To compare the effect of treatment with gonadotropin-releasing hormone agonist (GnRH-a) and human menopausal gonadotropins (hMG) with that of gonadotropins only, on the cumulative livebirth rate and miscarriage rate of pregnancies achieved in women with polycystic ovarian syndrome (PCOS).. Retrospective analysis of the outcome of 97 pregnancies according to the treatment protocol, with or without GnRH-a. Calculation of miscarriage rate and cumulative livebirth rate by life-table analysis.. Infertility clinic and in vitro fertilization (IVF) unit.. Women with polycystic ovaries (n = 239) who were clomiphene citrate failures and received either GnRH-a/hMG (n = 110) or gonadotropins only (n = 129) for ovulation induction (n = 138) or superovulation for IVF (n = 101).. For ovulation induction, hMG was given in a step-up, individually adjusted dose scheme. For IVF, three ampules of pure follicle-stimulating hormone were given for 3 days followed by three ampules per day hMG and then individual dose adjustment. Gonadotropin-releasing hormone agonist (Decapeptyl, D-Trp6, microcapsules, 3.75 mg) was given in a single dose 2 weeks before gonadotropin treatment.. The rate of early miscarriages (< 12 weeks) per pregnancies achieved was analyzed, and the cumulative livebirth rate for each treatment group was calculated by life-table analysis.. Miscarriage rates after treatment in ovulation induction with (16.7%) and without GnRH-a (39.4%) and in IVF with (18.2%) and without GnRH-a (38.5%) were almost identical and were therefore analyzed together. Of pregnancies achieved with GnRH-a, 17.6% miscarried compared with 39.1% of those achieved with gonadotropins alone. Cumulative livebirth rate after four cycles for GnRH-a was 64% compared with 26% for gonadotropins only.. Cotreatment with GnRH-a/hMG for anovulatory women with PCOS reduces the miscarriage rate and improves the livebirth rate compared with treatment with gonadotropins alone.

    To assess the effect of gonadotropin-releasing hormone agonist (GnRH-a) on pituitary suppression, subsequent ovarian response, and results of in vitro fertilization (IVF) treatments in polycystic ovarian syndrome (PCOS) patients.. Randomized prospective study.. In vitro fertilization program and endocrinologic institute.. Thirty patients with PCOS; 16 received GnRH-a, and 14 did not receive GnRH-a.. Ovum pick-up and embryo transfer.. Response to GnRH-a test, serum and follicular fluid (FF) hormonal measurements, steroid levels, and aromatse activity in granulosa cell (GC) culture, and results of IVF.. Pituitary responsiveness was abolished in all patients 14 days after GnRH-a administration, and early luteinization was prevented. Steroid levels in FF did not differ between the two groups. In GC culture, progesterone (P) levels were higher in patients without the GnRH-a (3,704 +/- 1,232 nmol/L versus 2,117 +/- 235 nmol/L; P less than 0.05) as were androstenedione (A) levels (5.3 +/- 1.0 nmol/L versus less than 3.5 nmol/L; P less than 0.05). However, aromatase activity and IVF results were similar in the two groups.. Administration of GnRH-a in patients with PCOS decreases P and A production by the GC cells and prevents early luteinization. It does not affect the IVF results.

Gonadotropin-releasing hormone agonist administration suppressed greater than 60% of the circulating levels of T and A, suggesting an ovarian origin. Minimal changes of DHEA, DHEAS, and cortisol were seen. With the addition of DEX, there was greater than 90% suppression of the total circulating A, T, DHEA, DHEAS, and cortisol, supporting the adrenal origin of the non-GnRH-a suppressible androgens. Excessive ovarian T and A secretion returned during the 90-day recovery study period in spite of rises of FSH concentrations that changed the ratio of FSH to LH in all subjects. Four of the six women failed to ovulate. In comparison of the women who did and did not ovulate during recovery, no differences in absolute levels or changes in concentrations of steroids or gonadotropins could be detected.. Using sequential and simultaneous administration of GnRH-a and DEX, we were able to delineate the contributions of the ovaries and adrenals to the abnormal steroidogenesis seen in PCOD. Despite prolonged suppression of ovarian and then adrenal steroidogenesis, ovarian dysfunction, evidenced by abnormal androgen production, returned with cessation of agonist administration.

IVF-ET in women with refractory polycystic ovarian disease.
    European journal of obstetrics, gynecology, and reproductive biology, 1989, Volume: 30, Issue:2

    Polycystic ovarian disease may be a cause of hormonal infertility. This condition is often refractory to therapy. Three groups of randomly chosen women with refractory polycystic ovarian disease (PCOD) were treated by induction of ovulation with pFSH/hCG, pFSH/hMG/hCG or after down-regulation of the ovaries with a GnRH analogue (Decapeptyl). Out of 18 patients six conceived in the first in vitro fertilization-embryo transfer (IVF-ET) cycle, and two further women conceived in a later cycle. It is suggested that patients with refractory PCOD should be referred for IVF-ET therapy, possibly after treatment with a GnRH analogue.

Management of multiple conceptions after gonadotropin-releasing hormone analog/human menopausal gonadotropin/human chorionic gonadotropin therapy.
    Fertility and sterility, 1988, Volume: 49, Issue:4

    The treatment course of a 31-year-old infertility patient due to PCO disease is presented. Because the patient failed to conceive after various treatment cycles with CC, she was subjected to a combined GnRHa/hMG/hCG therapy. After plasma E2 levels had reached 2400 pg/ml, three leading follicles, with diameters of 20 to 24 mm, were detected. Induction of ovulation was achieved by 10,000 IU hCG. The patient conceived and developed ovarian hyperstimulation. At 8 weeks of gestation, seven cystic structures were detected within the uterine cavity, five containing single embryos, and two with twin embryos. All nine embryos were vital, as evidenced by their heart beats. Embryo reduction was achieved by transabdominal puncture on three occasions. The three surviving fetuses were carried to the 34th week of gestation. After delivery by cesarean section, three healthy babies developed normally. This communication illustrates the complications that can be associated with ovulation induction in PCO disease: ovarian hyperstimulation, polyovulation, multiple conceptions, and their clinical management.

Sonographic monitoring of ovarian volume during LHRH analogue therapy in women with polycystic ovarian syndrome.
    Journal of ultrasound in medicine : official journal of the American Institute of Ultrasound in Medicine, 1988, Volume: 7, Issue:4

    Polycystic ovarian disease is characterized by menstrual disorders, infertility, obesity, and large ovaries. Large ovaries with multiple cysts are the direct cause of the high incidence of ovarian hyperstimulation during ovulation induction. Lately, gonadotropin-releasing hormone (GnRH) analogues have been employed to decrease ovarian steroidogenesis and thus reduce the incidence of ovarian hyperstimulation. In this study the ovarian size was ultrasonographically assessed during chronic GnRH analogue treatment, revealing a significant reduction in ovarian volume. This decrease in volume results in a reduced incidence of hyperstimulation, and we think the ultrasonic scanning can be effectively used to assess the success of GnRH treatment.

Induction of ovulation with D-Trp6-LHRH combined with purified FSH in patients with polycystic ovarian disease.
    Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology, 1988, Volume: 2, Issue:4

    Seventeen patients with polycystic ovarian disease (PCOD) and evidence of mild or severe ovarian hyperstimulation syndrome (OHSS) during therapy with CC/hCG, FSH/hCG or hMG/hCG were treated with D-Trp6-LHRH until medical gonadectomy was attained. Under the suppressive therapy with the GnRH agonist (GnRHa) ovulation was induced with FSH/hCG. In 15 out of 17 patients, ovulatory cycles were obtained with this new modality of treatment. Seven patients conceived (3 viable pregnancies and 4 early abortions) after the 1st treatment cycle. Fourteen of the 17 patients demonstrated symptoms of mild OHSS which did not require hospitalization. Only 1 patient developed severe OHSS after the combined treatment. Our results suggest that therapy with GnRHa, especially in its delayed release formulation, is effective for the prevention of severe ovarian hyperstimulation in PCOD patients undergoing treatment with menotropins for the induction of ovulation.

Gonadotropin-releasing hormone (GnRH) analog suppression renders polycystic ovarian disease patients more susceptible to ovulation induction with pulsatile GnRH.
    The Journal of clinical endocrinology and metabolism, 1988, Volume: 66, Issue:2

    Pulsatile GnRH administration consistently restores normal reproductive hormone levels and ovulation in women with hypogonadotropic hypogonadism, but is less effective in those with polycystic ovarian disease (PCOD). We pharmacologically created a hypogonadotropic condition with a GnRH analog (GnRH-A) in six women with PCOD to investigate the role of deranged gonadotropin secretion in PCOD and to improve the response to pulsatile GnRH ovulation induction. Before GnRH and GnRH-A treatment the women with PCOD had increased LH pulse frequency [one pulse every 55 +/- 2 (+/- SE) min; P less than 0.05] and LH pulse amplitude (10.9 +/- 1.4 U/L; P less than 0.05) compared to normal women in the follicular phase of their menstrual cycle. Each PCOD woman completed one cycle of pulsatile GnRH administration for ovulation induction before (pre-A cycles; n = 6) and one or two cycles after (post-A cycles; n = 9) GnRH-A administration [D-Ser(tBu)6-Des,Gly10-GnRH; 300 micrograms, sc, twice daily for 8 weeks]. Pulsatile GnRH (5 micrograms/bolus) was given at 60-min intervals using a Zyklomat pump. Daily blood samples were drawn during the pulsatile GnRH ovulation induction cycles for the determination of serum LH, FSH, estradiol (E2), progesterone, and testosterone, and pelvic ultrasonography was done at 1- to 4-day intervals. Mean (+/- SE) serum LH levels were elevated during the pre-A cycle (49.2 +/- 3.1 IU/L) and decreased to normal levels during the post-A cycles (19.6 +/- 1.4 IU/L; P less than 0.0001). Mean testosterone concentrations were lower during the post-A cycles [88 +/- 2 ng/dL (3.1 +/- 0.1 nmol/L)] than during the pre-A cycles [122 +/- 3 ng/dL (4.2 +/- 0.1 nmol/L); P less than 0.0001]. In the follicular phase of the post-A cycles E2 levels were significantly lower [81 +/- 5 pg/mL (300 +/- 20 pmol/L) vs. 133 +/- 14 pg/mL (490 +/- 50 pmol/L); P less than 0.0001], preovulatory ovarian volume was smaller (24.6 +/- 2.0 vs. 31.4 +/- 2.4 cm3; P less than 0.01), and the FSH to LH ratio was higher (0.56 +/- 0.03 vs. 0.16 +/- 0.01) than in the pre-A cycle, suggesting more appropriate function of the pituitary-gonadal axis. Excessive LH and E2 responses to pulsatile GnRH administration in the early follicular phase of the pre-A cycle were abolished in the post-A cycles.(ABSTRACT TRUNCATED AT 400 WORDS)

Induction of ovulation in polycystic ovary syndrome with a combination of a luteinizing hormone-releasing hormone analog and exogenous gonadotropins.
    Fertility and sterility, 1987, Volume: 47, Issue:6

    Eight clomiphene citrate (150 mg/day for 5 days)-resistant anovulatory women with polycystic ovary were included in this study. A luteinizing hormone-releasing hormone (LH-RH) analog, D-Trp-6-LH-RH, 100 micrograms subcutaneous-per day, induced a hypogonadotropic state within varying periods but at most within 3 weeks, after an initial flare-up effect characterized by slight increase in ovarian size in four patients and in the other four by cysts that disappeared rapidly. On the 28th day or 15 to 20 days after menstruation for subsequent cycles, during maintenance of D-Trp-6-LH-RH therapy, a usual gonadotropin regimen was carried out in 33 cycles. Human menopausal gonadotropins obtained follicular maturation in all cycles. However, there was never the growth of a single dominant follicle but always of several follicles. Human chorionic gonadotropin then induced ovulation in 31 cycles (94%). Luteal phase was normal in 28 and inadequate in 3 of the 31 ovulatory cycles. Hyperstimulation, generally mild to moderate but rather severe in 2 cycles, was constant. Five pregnancies were obtained. The overall pregnancy rate was 15% per cycle and 17.8% per normoovulatory cycle. This study showed that an associated treatment with an LH-RH analog enables gonadotropins to achieve ovulation regularly with an encouraging number of pregnancies but at a risk of hyperstimulation.

Abolishment of the positive feedback mechanism: a criterion for temporary medical hypophysectomy by LH-RH agonist.
    Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology, 1987, Volume: 1, Issue:1

    The hypothalamic pituitary axis was studied in patients with an abnormal pattern of gonadotropin release during chronic treatment with LH-RH agonist. Two patients had PCOD and the third demonstrated the early luteinization phenomenon. Following a well-defined gonadotropin rise with initiation of LH-RH treatment, no further response was noted. Stabilization of the LH:FSH ratio in PCOD patients was noted after 4 weeks of treatment. Administration of both native LH-RH (100 micrograms) and intravenous pulsatile LH-RH did not evoke any rise in LH. In addition to the above LH-RH challenges, the positive feedback was examined by administration of estradiol benzoate (EB). The study demonstrated that, although the pituitary did not respond to any LH-RH challenge, it may still respond by a rise in LH following EB administration. Both functions of the hypothalamic pituitary axis should be examined in order to determine the state of medical hypophysectomy.

Dynamics of plasma gonadotropin and sex steroid release in polycystic ovarian disease after pituitary-ovarian inhibition with an analog of gonadotropin-releasing hormone.
    The Journal of clinical endocrinology and metabolism, 1987, Volume: 64, Issue:5

    To assess the dynamics of the suppression and recovery of plasma gonadotropins and sex steroids during and after inhibition of pituitary-ovarian function by a long-acting agonist GnRH-analog (GnRH-A), eight patients with polycystic ovarian disease were treated with 12 micrograms/kg X day GnRH-A for 56 consecutive days. In response to GnRH-A, these patients had a sharp and pronounced decline of their initially elevated immunoreactive LH and bioactive LH (bioLH) levels. Plasma immunoreactive FSH levels declined more rapidly than did bioLH, but the FSH decline was less sustained. Plasma testosterone, androstenedione, and estrone (E1) levels also declined during GnRH-A administration. The pattern of plasma androgen decrease resembled that of bioLH. There was a positive correlation between bioLH and the two androgens (r = 0.85; P less than 0.05, by Spearman's rank correlation, for both hormones). Cessation of GnRH-A administration was followed by prompt progressive increases in gonadotropin and androgen concentrations to pretreatment values. FSH recovered faster than bioLH. BioLH plasma concentrations reached pretreatment values by day 28. The recovery of plasma androstenedione and testosterone levels correlated positively with that of bioLH. Although plasma E1 levels were higher during the recovery period than during treatment, they never reached the concentrations found during the basal period, whereas estradiol concentrations were slightly but not significantly higher than those in the basal period. As a consequence, the E1 to estradiol ratio, very high in the basal period, approximated unity during recovery. These data indicate that hyperandrogenism in polycystic ovarian disease is gonadotropin dependent and accompanied by a relative abundance of LH bioactivity basally and during GnRH-A administration. Thus, the relative increase in bioLH secretion appears to be independent of the rate of gonadotropin secretion and the circulating sex steroid concentrations.

NIH conference. Therapeutic applications of luteinizing-hormone-releasing hormone and its analogs.
    Annals of internal medicine, 1985, Volume: 102, Issue:5

    The chemical structure of luteinizing-hormone-releasing hormone (LHRH) was discovered in 1971 after more than a decade of intensive effort. Subsequent physiologic studies in primates and humans showed that the biologic activity of LHRH depends on the way in which the hormone is administered. Pulsatile administration of LHRH, which mimics the natural secretory pattern, causes sustained secretion of the gonadotrophins. This method of administration has been used to induce ovulation in women with hypothalamic amenorrhea and to induce puberty and spermatogenesis in men with hypogonadotrophic hypogonadism. Continuous infusion, however, produces only transient stimulation of gonadotrophin secretion, followed by a "desensitization" response in which gonadotrophin secretion is inhibited. Thus, LHRH can either augment or inhibit gonadotrophin secretion depending on the mode of administration. Recently, long-acting synthetic analogs of LHRH have been shown to desensitize the pituitary gland and inhibit gonadotrophin release when administered as a single daily subcutaneous injection. These LHRH analogs have proved highly effective in the treatment of prostatic carcinoma and central precocious puberty. They are also being studied as a new approach to contraception and to the treatment of endometriosis and polycystic ovary syndrome.

Stimulation of LH fragments with reduced bioactivity following GnRH agonist administration in women.
    The Journal of clinical endocrinology and metabolism, 1984, Volume: 58, Issue:4

    In eumenorrheic women with endometriosis and in oligo-amenorrheic women with polycystic ovarian disease (PCO), chronic administration of a long-acting GnRH agonist (GnRH-a) reduced the circulating concentrations of estrogens and androgens to levels similar to those of castrated women. The concommittant elevation of LH in both groups suggested that the measured immunoreactive LH had reduced bioactivity. In seven women with endometriosis, bioactive LH (BA LH) measured as the in-vitro secretion of testosterone by dispersed Leydig cells, was significantly (p less than 0.001) reduced from 10.8 +/- 1.2 (SEM) to 4.4 +/- 0.2 mIU/ml at the end of 28 days of GnRH-a therapy. In five women with PCO, BA LH decreased from 44.2 +/- 15.5 to 5.7 +/- 0.6 mIU/ml (p = 0.06). These changes of BA LH appeared to be responsible for the suppression of ovarian androgen secretion during GnRH-a treatment and in turn may have contributed to the profound decreases of estrogen production by reducing the amount of precursor androgen available for aromatization. Free alpha subunit levels increased simultaneously with the decrease of BA LH at the end of therapy, suggesting a post-receptor effect of GnRH-a. Beta subunit levels became undetectable. Cross-reaction of alpha subunit in the RIA for LH was sufficient to only partially account for the LH levels measured. On sephadex G-100 chromatography the excess immunoreactive material was detected at and immediately following the alpha subunit tracer. Further studies will be necessary to elucidate the chemical nature of the immunoreactive LH secreted during GnRH-a therapy.

Steroid secretion in polycystic ovarian disease after ovarian suppression by a long-acting gonadotropin-releasing hormone agonist.
    The Journal of clinical endocrinology and metabolism, 1983, Volume: 56, Issue:5

    The principal glandular source of increased serum androgens in polycystic ovarian disease (PCO) is controversial), since complete separation of ovarian from adrenal function has not been achieved. The purpose of this study was to determine whether a long-acting GnRH agonist could be used to selectively inhibit ovarian steroid secretion in PCO and ovulatory women. Each of five typical PCO patients and six ovulatory subjects on day 2 of their menstrual cycles received D-Trp6-Pro9-NEt-LHRH (GnRH-a; 100 micrograms) for 28 consecutive days. Their results were compared to basal serum hormone values in eight oophorectomized women. In response to GnRH-a, PCO and normal subjects exhibited sharp and sustained rises of LH and gradual decreases in FSH. These levels were clearly less than basal levels seen in oophorectomized women. Episodic LH release was significantly attenuated in both groups at the end of GnRH-a treatment. After the administration of agonist, serum estradiol (E2), estrone (E1), androstenedione (A), and testosterone (T) were suppressed to castrate levels in both groups. The decrements of E2 and E1 in PCO were gradual and continuous compared to initial dramatic rises, which reached peaks at 14 days, and subsequent abrupt falls in the ovulatory controls. Serum A and T declined steadily in both groups. Basal serum dehydroepiandrosterone and dehydroepiandrosterone sulfate, but not cortisol, levels were elevated in PCO subjects. The 24-h secretion patterns and responses to ACTH of these hormones in PCO and ovulatory subjects were unaltered by GnRH-a administration. These data demonstrate that 1) in PCO subjects, GnRH-a induced complete suppression of ovarian steroid secretion, as circulating levels at the end of treatment were comparable to those seen in our oophorectomy subjects; 2) elevated A and T levels in PCO patients were derived primarily from the ovary; and 3) adrenal steroid secretion was unaltered by GnRH-a in both PCO and normal women.
