    Abstract:
    Twenty-eight hyperandrogenemic women suffering from infertility owing to chronic anovulation were treated with hMG. Only 7 patients exhibited the typical polycystic ovarian appearance of multiple subcortical cysts, however, a wide range (6-15 cm3) of ovarian volume was observed. The LH/FSH ratio was consistently lower than 2.5 and circulating androgens of both ovarian and adrenal origin were elevated. The 4 days dexamethasone suppression test showed more than 80% suppression of dehydroepiandrosterone-sulphate and a variable (40-60%) reduction of testosterone and androstenedione levels. Two different patterns of follicular development were observed in response to hMG. Sixteen patients exhibited polycystic ovarian reaction, whereas 12 women had a follicular growth pattern similar to that seen in hMG-stimulated normo-ovulatory subjects. Patients with polycystic ovarian reaction showed a significantly increased androstenedione response to hMG when compared with the other group. Moreover, the non-stimulated ovarian volume was found to be markedly greater than in subjects without polycystic reaction. Thus, ovarian stimulation of patients with mixed hyperandrogenemia may elucidate the presence of borderline polycystic ovaries; furthermore the increased accumulation of androstenedione may suggest an inherent ovarian failure.
