title: Sexual function and fertility in adult females and males with congenital adrenal hyperplasia.
abstract: Female patients with classic 21-hydroxylase deficiency (21-OHD) present with decreased fertility and low childbirth rates, women with a salt-wasting form of 21-OHD being most severely affected. In cases of undersubstitution with glucocorticoids, tonic androgen secretion disturbs ovulation. However, even adequately substituted females may present with apparent infertility. Despite adrenal androgen suppression, adrenal progesterone secretion can prevent thickening of the endometrium in the follicular phase. Furthermore, functional ovarian hyperandrogenism is a common finding even in women with well-controlled classic 21-OHD. Psychosexual factors may also contribute significantly to decreased childbirth rates found in these patients. Genital ambiguity may lead to a disturbed body image and the patients have been found to feel less feminine than healthy control women. The repeated psychological insult caused by frequent genital examinations and operations is also important, though its exact impact has been difficult to determine. Finally, prenatal androgen excess can cause masculinization of the central nervous system leading to boyish behavior in childhood and decreased heterosexual activity in adulthood. Some recent reports show a high rate of infertility also in men with 21-OHD. They are at risk of benign testicular tumors, adrenal rests, which can lead to permanent infertility. Also, raised adrenal androgen production leading to increased estrogen concentrations can suppress gonadotropin secretion and may lead to a hypogonadotropic state.
