RESUMO
A retrospective study was conducted on one patient with postmenopausal hyperandrogenism. The postmenopausal female patient was found with significant hyperandrogenism ( total testosterone 6. 4 nmol/ L) and hirsutism, with normal adrenal androgen ( dehydroepiandrosterone-sulfate ) level. Computed tomography and ultrasound did not detect any ovarian and adrenal mass. Positron emission tomography revealed without high metabolic region, either. Ovarian and adrenal vein catheterization did not reveal any positive result. Obviously, ovary-derived hyperandrogenism was highly suspected, but the patient still refused any surgical exploration. After a trial of a single dose of gonadotropin releasing hormone analogue(GnRHa) triptorelin, increased testosterone level returned to normal along with decreasing level of gonadotropin. Multiple doses were needed for maintenance of testosterone at normal level with the intervals of 2 ～ 12 months. This response to the treatment was consistent with that of gonadotropin dependent hyperandrogenism.
