Abstract:
Recent onset of hirsutism in postmenopausal women is mostly caused by androgen secretion from adrenal or ovarian tumours. Ovarian hyperthecosis (OH) is a cause of hyperandrogenism in premenopausal women, few cases of postmenopausal presentation have been described. We report on a 73-year old women with androgenic alopecia and hirsutism of recent onset because of elevated testosterone levels. Radiologic imaging showed no tumours of the adrenal glands and ovaries. Careful re-evaluation revealed increased ovarian size in relation to age. Bilateral ovarectomy confirmed the diagnosis of ovarian hyerthecosis and led to improvement of clinical findings. It is important to review imaging findings as OH may elude imaging studies. OH should be included in the differential diagnosis of postmenopausal hyperadnrogenism particularly if androgen excess is of recent-onset.

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.

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...
