Abstract:
Daily plasma hormones, including luteinizing hormone (LH), follicle-stimulating hormone (FSH), estrone (E1), estradiol (E2), progesterone, androstenedione, and testosterone (T), were measured in 16 anovulatory patients for a span of 3 to 4 weeks. The clinical diagnoses in this group of patients included the following: anovulation-eumenorrhea (n = 5), anovulation-polymenorrhea (n = 1), anovulation-oligomenorrhea (n = 3), congenital adrenal hyperplasia (n = 1), polycystic ovarian disease (n = 4), severe hypothalamic amenorrhea (n = 1), and postpartum amenorrhea-galactorrhea (n = 1). Follicular activity was evident in polymenorrheic and oligomenorrheic patients, and menstruation occurred in these patients following estrogen withdrawal. No follicular maturation was noted in the group of patients with anovulation-eumenorrhea, and menstruation in these patients was considered breakthrough bleeding. Low FSH levels were observed in anovulatory patients with eumenorrhea, polymenorrhea, and oligomenorrhea. Significantly high LH values were noted in both classic and non-classic polycystic ovarian disease. Extremely low E1 and E2 levels were found in patients with severe hypothalamic amenorrhea and postpartum amenorrhea-galactorrhea. Slightly elevated progesterone levels were observed in polymenorrheic and oligomenorrheic patients prior to menstruation; this was frequently associated with an LH surge or elevation. Elevated T levels were consistently associated with hirsutism but not with obesity.
