Abstract:
Postmenopausal hyperandrogenism is rare, and without consensus on specific investigative indices, diagnosis is challenging. A 77-year-old woman had a three-year history of hirsutism, male-pattern baldness and increased libido alongside elevated androstenedione, total testosterone and free androgen index levels. A magnetic resonance imaging (MRI) scan showed bilateral ovarian lesions, suggesting ovarian hyperthecosis. Histopathology obtained after a laparoscopic bilateral salpingo-oophorectomy confirmed ovarian hyperthecosis and hilus cell hyperplasia. We believe it's the first time they have been reported to occur in combination. The symptoms resolved within a month of surgery. This case highlights the difficulties of diagnosis alongside demonstrating the importance of management by a multidisciplinary team.

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...
