Abstract:
Urinary and serum steroid measurements were obtained in a 48-year-old female before and after the removal of a virilizing granulosa cell tumor (GCT). Preoperatively, serum testosterone was markedly elevated while 17-ketosteroid (17-KS) and estrogen excretion were normal. Chorionic gonadotropin administration effected a marked rise in urinary 17-KS excretion and serum testosterone while oral contraceptive therapy for 21 days decreased serum testosterone to normal. With tumor resection, serum testosterone fell to normal and subsequent administration of HCG had no stimulatory effect on serum testosterone or urinary 17-KS excretion. The patient's clinical response and 8-year followup attest to the tumor's unusual virilizing role.

Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.

Folliculogenesis
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
