Abstract
Female androgen excess typically presents with hirsutism, acne, and frontotemporal alopecia. Although the majority of cases are due to underlying polycystic ovary syndrome, non-polycystic ovary syndrome pathology can present a diagnostic and therapeutic challenge. We present 3 cases highlighting the utility of GnRH analogues in diagnosis and treatment of ovarian hyperandrogenism. In case 1, we highlight the role of GnRH analogue testing to localize severe postmenopausal androgen excess, allowing full resolution of symptoms following resection of a benign ovarian steroid-cell tumor. Our second case demonstrates the dual utility of GnRH analogues as both a diagnostic and therapeutic agent for hyperandrogenism in a premenopausal woman with severe insulin resistance. We observed suppression of serum testosterone coupled with significant improvement in hirsutism scores. The final case describes GnRH analogue suppression as a therapeutic option for a postmenopausal woman with ovarian hyperthecosis wishing to avoid surgical intervention, with successful symptom resolution. This case series delineates the applications of GnRH analogue suppression in a variety of clinical contexts, in particular their potential role in controlling symptoms in cases of refractory androgen excess and an alternative to surgery in cases of benign ovarian hyperandrogenism.
