Gonadotropin therapy for anovulation is highly successful: 58.6% of treated patients conceive. Better results are achieved in patients with galactorrhea-amenorrhea (77.1%) and hypogonadotropic hypogonadism (63.3%) than in patients with normal gonadotropin levels (45.4%). The spontaneous abortion rate (27.5%) is somewhat higher than that in spontaneous pregnancies. The multiple pregnancy rate is 31% and was slightly lower in cycles with preovulatory estrogen levels in the physiologic range. In patients treated with human menopausal and chorionic gonadotropins for 7 to 9 days per cycle, the multiple pregnancy rate is considerably less (12.9%) than in patients with longer treatment. The efficacy of treatment does not diminish with repeat-treatment cycles.
