title: Ovulation induction with pulsatile gonadotropin-releasing hormone administration in patients with polycystic ovarian syndrome.
abstract: Gonadotropin-releasing hormone (0.025 microgram/kg) was administered intravenously in a pulsatile fashion to four subjects with polycystic ovary syndrome for a total of six cycles. Five of the six cycles culminated in ovulation, although in one course the response occurred too early to be attributed to the therapy alone. No pregnancies resulted. All luteal phases were of normal duration, but progesterone production as manifested by serum progesterone determination was deficient in some. If additional investigation confirms these preliminary findings, this form of therapy may offer a safe and economic alternative for anovulatory patients refractory to clomiphene citrate therapy. The response of the four subjects suggests that pulsatile gonadotropin-releasing hormone administration may override hypothalamic-pituitary dysfunction and result in ovulatory menstrual cycles.
