The effect of gonadotropin suppression on the induction of ovulation in premature ovarian failure patients.
Ovulation induction in patients with hypergonadotropic premature ovarian failure is rarely successful. The authors have attempted to reproduce the results of recent case reports that suggest that ovulation and pregnancy can be successfully achieved when estrogen therapy precedes or coincides with ovarian stimulation with human menopausal gonadotropins (hMG). Fourteen patients with idiopathic premature ovarian failure underwent gonadotropin suppression and attempted ovulation induction with at least one of three regimens, which were as follows: 1) Group A: estrogen-induced suppression followed by hMG stimulation (n = 4). 2) Group B: estrogen-induced suppression followed by hMG stimulation with concomitant estrogen therapy (n = 10). 3) Group C: gonadotropin-releasing hormone agonist-induced gonadotropin suppression followed by concomitant hMG stimulation (n = 6). Despite complete gonadotropin suppression and high-dose hMG therapy in all three groups, ovulation occurred in only a single patient in group C. Pregnancy did not ensue. These data fail to corroborate previous case reports.
