phytoestrogens and Dyspareunia

The aim of this overview was to evaluate the effectiveness of phytoestrogens on vaginal health and dyspareunia in peri- and post-menopausal women.. Three databases including MEDLINE, Scopus and the Cochrane Central Register of Controlled Trials were from inception to August 2017.. Two systematic reviews and 11 RCTs were included in the overview. According to the findings, isoflavones increased the maturation value and attenuated the vaginal atrophy in the post-menopausal women. Topical isoflavones had beneficial effects on the vaginal atrophy. Similar efficacy was found in Pueraria mirifica and conjugated estrogen cream on dryness ( p = 0.277), soreness ( p = 0.124) and irritation ( p = 0.469), as well as discharge ( p = 0.225) and dyspareunia ( p = 0.089). However, the conjugated estrogen cream was more effective compared to Pueraria mirifica ( p > 0.005) regarding maturation index improvement. Comparison of fennel 5% vaginal cream and placebo gel showed significant difference in superficial cells ( p < 0.01), parabasal cells ( p < 0.01) and intermediate cells ( p < 0.01), whereas no difference was found between the oral fennel and placebo in terms of superficial, parabasal and intermediate cells as well as Maturation value. Administration of 80 mg red clover oil had a significant effect on superficial ( p < 0.005), intermediate ( p < 0.005) and parabasal and vaginal dryness ( p < 0.005) compared to the placebo. Flaxseed had also a trivial effect on maturation value. Genistein had a more prominent effect on the genital score. The severity of dyspareunia decreased by 27%.. Phytoestrogens have various effects based on administration route and type on the vaginal atrophy.

This systematic review and meta-analysis aimed to critically evaluate the effectiveness of phytoestrogens on sexual disorders and severity of dyspareunia.. Relevant studies were identified through a systematic search of major databases such as PubMed, Cochrane Library, ISI Web of Science, and Scopus up to 29 September 2017, without any time limit. Two independent reviewers screened all abstracts and full-text articles. The final version of Jadad scale was used for evaluating the quality of trials.. Soy did not have an effect on sexual function (standardized mean difference [SMD] = 1.099 [95% CI: -3.033 to 0.835, p = 0.265]; heterogeneity I. Phytoestrogens have various effects on sexual function. Published reports show that maritime pine bark, T. foenum-graecum L., and F. vulgare could be considered as agents to overcome sexual dysfunctions while soy, red clover, genistein, and flaxseed had no promising effects on these conditions.

In developed countries, women spend more than one-third of their life in the menopause and at least half of them experience vasomotor symptoms that impair their normal function and well-being. Long-term estrogen replacement therapy (HRT) with estrogen can suppress typical menopausal symptoms and prevents osteoporosis. When estrogen-only HRT is started within 10 years after the menopause, the prevalence of cardiovascular disease is reduced, mortality is lower, and the risk of breast cancer is not significantly increased. Postmenopausal genital and urinary problems with recurrent infections, incontinence, and dyspareunia can effectively be treated by vaginal application of estriol, which seems to be safe for women treated for breast cancer. HRT after the age of 60 years is associated with a lower number needed to treat than number needed to harm, implying that there would be one unfavorable side-effect for up to ten women experiencing a positive effect. However, further studies are needed regarding the risk-benefit ratio of HRT in women over 70 years. It is concluded that transdermal substitution therapy with estradiol may increase the number of quality-adjusted life years of postmenopausal women. The combination with nutriceutical food supplementation may add to this benefit, but complementary prospective trials are still needed.

To compare the effects of a 12-week treatment with Pueraria mirifica (PM) gel or a conjugated estrogen cream on vaginal maturation index, vaginal symptom score, vaginal health assessment score, and vaginal flora in postmenopausal women.. In a prospective, noninferiority, randomized controlled study, 82 postmenopausal women with at least one vulvovaginal symptom, that is, dryness, soreness, irritation, dyspareunia, or discharge, were recruited. Participants were randomly assigned into two groups for treatment with either PM gel or conjugated estrogen cream (CEE). The treatment regimen consisted of application of 0.5 g of product intravaginally daily for 2 weeks, and then decreased to three times per week for 10 weeks. Vaginal maturation index, vaginal symptoms score, and vaginal health assessment score were evaluated before the beginning of the study and at 6 weeks and 12 weeks after treatment with PM or CEE.. The vaginal maturation index increased significantly in both treatment groups at week 12, from 22.44 ± 22.28 to 47.56 ± 29.00 and from 27.07 ± 26.12 to 66.90 ± 22.42 in the PM and the CEE groups, respectively (P < 0.05). A significantly higher effect was, however, observed in the CEE group (P < 0.05). Vaginal symptom scores decreased significantly after treatment in both groups, from 4.37 ± 2.79 to 0.95 ± 1.88 and from 4.15 ± 2.16 to 0.68 ± 1.64 in the PM and the CEE groups, respectively (P < 0.05), with no statistically significant different between the two groups (P > 0.05).. The use of a 12-week treatment regimen with Pueraria mirifica gel was shown to be efficacious and safe for the treatment of vulvovaginal atrophy. Conjugated estrogen cream was found to be more effective compared to Pueraria mirifica gel in improving signs of vaginal atrophy and restoring vaginal epithelium at 6 and 12 weeks.

Evaluate the effects of vaginal administration of isoflavones derived from Glycine max (L.) Merr. as a treatment option for vaginal atrophy, on the morphology and expression of estrogen receptors in vaginal epithelium of postmenopausal women.. The double-blind, randomized, placebo-controlled, clinical trial. Sixty women were treated for 12 weeks with isoflavone vaginal gel 4% (1g/day) and a placebo gel. After 4 and 12 weeks, the vaginal atrophy symptoms were classified at none, mild, moderate and severe and the vaginal cytology were taken to determine the maturation value. Vaginal pH was measured at the beginning and end of therapy. Microbiopsies in vaginal fornix were performed before the treatment and after 12 weeks of treatment.. Isoflavone vaginal gel was effective for relief of vaginal dryness and dyspareunia symptons and an increase in the intermediate and superficial cells was noted. The vaginal pH in the isoflavone group was 7.1 at baseline and 5.4 after 12 weeks, whereas in the placebo group there was no significant change. A significant increase in thickness after treatment was detected in the Isoflavone Group. The percentage of estrogen receptor positive cells in vaginal epithelium for the Isoflavone Group ranged from 58.5% at the beginning of treatment to 82.6% after 12 weeks. These results were superior to placebo gel.. Glycine max (L.) Merr. at 4% vaginal gel on a daily basis in postmenopausal women led to improvements in vaginal atrophy symptoms, maturation values, vaginal pH, morphology and expression of estrogen receptors in vaginal epithelium. Isoflavones proved good treatment options for relief of vulvovaginal atrophy.

Female sexual dysfunction (FSD) is a complex and multifactorial condition. An increased incidence of FSD is especially associated with the decline of estrogen. Thus, menopause is a critical phase for FSD complaints. In this context, medicinal plants may be a therapeutic option.. To identify and describe the popular and clinical uses of medicinal plants for FSD treatment in climacteric women. We highlighted the majority of the plants commonly involved with the female reproductive system including: Angelica sinensis, Cimicifuga racemosa, Ferula hermonis, Ginkgo biloba, Humulus lupulus, Lepidium meyenii, Tribulus terrestris, Trifolium pratense, and Vitex agnus-castus.. This study is a narrative review of studies of plants that are possible alternative treatments for FSD. The species described have clinical and popular uses in different cultures as well as medical indications for female reproductive disturbances, mainly in climacteric women. We have also analyzed the evidence level of clinical studies.. The main outcome assessed is the efficacy of plants in improving the symptoms of FSD.. There is little evidence from the literature to recommend the use of medicinal plants when treating FSD. The majority of studies with a strong level of evidence are associated with the treatment of the vasomotor symptoms of menopause. Ferula hermonis, Angelica sinensis, and Gingko biloba may be suggested for arousal disorder studies. Cimicifuga racemosa, Trifolium pratense, and Vitex agnus-castus may be recommended for several FSD. Humulus lupulus and Tribulus terrestris may help with desire disorder studies. Lepidium meyenii should be studied further.. Studies of these plants indicate that they may be useful as a possible alternative and/or complementary approach for studies aimed at the treatment of FSD. At this time, however, this review cannot recommend a plant that has a strong enough level of evidence for treatment of FSD. Thus, there is a need for clinical (double-blinded and randomized) studies to evaluate the efficacy and safety of several plants that can exert a positive effect on the management of FSD.
