Abstract
Anovulatory infertility in 134 women was treated with gonadotropins for a total of 318 cycles. The patients were classified into WHO group I, hypothalamic-pituitary failure (72 patients), and WHO group II, hypothalamic-pituitary dysfunction (62 patients). All patients in this group had failed to achieve pregnancy with clomiphene citrate therapy in repeated cycles. The pregnancy rate in group I was 72.2% vs 17.7% in group II. The 'take home' baby rate was 57.1% in group I vs 13.1% in group II. The rate of miscarriages was 14.3% without any significant difference between the groups. Multiple pregnancies occurred only in group I patients (19.2%). The conception rate was highest in the first four cycles, whereas no patient became pregnant after the sixth treatment cycle. Ovarian hyperstimulation syndrome occurred most frequently in group II patients, however, overall only 2.2% of the patients needed hospitalization because of hyperstimulation. Gonadotropin therapy must be considered an efficient and successful treatment of infertility in patients with hypothalamic-pituitary failure, whereas the success rate is rather poor in patients with hypothalamic-pituitary dysfunction.
