menotropins and Adrenal-Hyperplasia--Congenital

Subfertility is defined as the condition of being less than normally fertile though still capable of effecting fertilization. When these subfertile couples seek assistance for conception, a thorough evaluation of male endocrine function is often overlooked. Spermatogenesis is a complex process where even subtle alterations in this process can lead to subfertility or infertility. Male endocrine abnormalities may suggest a specific diagnosis contributing to subfertility; however, in many patients, the underlying etiology is still unknown. Optimizing underlying endocrine abnormalities may improve spermatogenesis and fertility. This manuscript reviews reproductive endocrine abnormalities and hormone-based treatments.

Classical congenital adrenal hyperplasia (CAH), a genetic disorder characterized by 21-hydroxylase deficiency, impairs male fertility, if insufficiently treated.. A 30-year-old male was referred to our clinic for endocrine and fertility assessment after undergoing unilateral orchiectomy for a suspected testicular tumor. Histopathological evaluation of the removed testis revealed atrophy and testicular adrenal rest tumors (TARTs) and raised the suspicion of underlying CAH. The remaining testis was also atrophic (5 ml) with minor TARTs. Serum 17-hydroxyprogesterone levels were elevated, cortisol levels were at the lower limit of normal range, and gonadotropins at prepubertal levels, but serum testosterone levels were within the normal adult range. Semen analysis revealed azoospermia. CAH was confirmed by a homozygous mutation g.655A/C>G (IVS2-13A/C>G) in CYP21A2. Hydrocortisone (24 mg/m(2)) administered to suppress ACTH and adrenal androgen overproduction unmasked deficient testicular testosterone production. As azoospermia persisted due to sustained hypogonadotropic hypogonadism, a combined s.c. gonadotropin replacement with human chorionic gonadotropin (hCG) (1500 IU twice weekly) and FSH (human menopausal gondadotropin (hMG) 150 IU three times weekly) was initiated.. Normalization of testosterone levels and a stable low sperm concentration (0.5 mill/ml) with good sperm motility (85% A+B progressive) were achieved within 21 months of treatment. Despite persisting TARTs, while receiving treatment, the patient successfully impregnated his wife twice, the latter impregnation leading to the birth of a healthy girl.. TARTs in unrecognized (simple virilizing) CAH may lead to unnecessary orchiectomy. In hypogonadotropic, azoospermic CAH, a combined treatment with oral corticosteroids and subcutaneously administered hCG and FSH can successfully restore testicular testosterone production and fertility, even if only one hypoplastic and atrophic testis with adrenal rest tumors is present.

A girl with congenital adrenal hyperplasia due to 21-hydroxylase deficiency could not be controlled by conventional treatment, and was adrenalectomized at age 8.5 years (bone age 13.5 years). After surgery, puberty and menarche occurred. On replacement therapy, her progress was uneventful up to the age of 16 years, when menstruations ceased and signs of virilization reappeared. Testosterone, androstenedione, and 17-hydroxyprogesterone in plasma, and pregnanetriol in urine were high, but DHEA in plasma, and pregnenetriol and pregnanetriolone in urine were low. Oestrogens in plasma were normal. There was no steroid response to ACTH, and marked, but somewhat slow suppression by dexamethasone. HMG induced a strong rise in oestrone and oestradiol. Ethinyloestradiol reduced not only oestradiol in plasma, but also testosterone, androstenedione, and 17-hydroxyprogesterone. With subsequent dexamethasone treatment, menstruation restarted, and the values returned to normal. It is concluded that virilization may reoccur in patients with 21-hydroxylase deficiency even after adrenalectomy, and that the ovaries in this patient contain some tissue, which has properties of adrenal (suppressibility by dexamethasone) and ovarian tissue (suppressibility by ethinyl oestradiol, preference for delta 4-pathway, low steroid 11-oxygenation) at the same time.
