The use of exogenous gonadotropins for treatment of clomiphene-resistant chronic anovulation in women with the polycystic ovary syndrome (PCO) is hazardous and often ineffective, possibly because of the abnormal endogenous gonadotropin secretion characteristic of PCO. We evaluated the effect of leuprolide acetate, a long-acting GnRH agonist, on serum gonadotropin and sex steroid concentrations before and during human menopausal gonadotropin (hMG) induction of ovulation in women with PCO. In this controlled prospective randomized study, leuprolide was administered daily for 4 weeks, followed by concomitant hMG administration. Gonadotropin and steroid hormone concentrations were compared with those during ovulation induction cycles in women with PCO receiving hMG only. Daily administration of leuprolide for 4 weeks resulted in significantly decreased serum LH, estradiol, and testosterone concentrations, but no change in serum progesterone, FSH, and dehydroepiandrosterone sulfate. Compared to ovulation induction using hMG alone, leuprolide administration before and during hMG treatment prevented preovulatory rises in serum LH and P concentrations, while having no effect on serum FSH, testosterone, estradiol, and dehydroepiandrosterone sulfate. We conclude that leuprolide administered to women with PCO decreases gonadal steroid production and is capable of preventing premature luteinization during hMG induction of ovulation.
