title: Buserelin suppression of endogenous gonadotropin secretion in infertile women with ovarian feedback disorders given human menopausal/human chorionic gonadotropin treatment.
abstract: Fifty infertile women with oligomenorrhea, anovulation, or luteal phase defects were selected for a combined therapy consisting of a gonadotropin-releasing hormone analog (Buserelin Hoechst AG, Frankfurt/Main, FRG) and human menopausal gonadotropin/human chorionic gonadotropin (hMG/hCG). Serving as their own controls, these women had been subjected to a total of 238 hMG/hCG treatment cycles with no pregnancy observed (average, 4.7 cycles; range 2 to 14). Of these 238 hMG/hCG cycles, only 98 (41.1%) appeared normal, while the others showed symptoms consistent with inadequate follicle maturation, luteal phase defects, and premature luteinization. In contrast, 89 cycles from 133 combined buserelin/hMG/hCG treatment cycles (66.9%) appeared to be normal, with no evidence of premature luteinization, and 21 patients became pregnant. These data indicate that the likelihood of group II World Health Organization (WHO) patients becoming pregnant with hMG/hCG therapy may be enhanced when endogenous gonadotropin secretion is suppressed at the same time.
