Use of combined exogenous gonadotropins and pulsatile gonadotropin-releasing hormone in patients with polycystic ovarian disease: a new approach to induction of ovulation

A combined regimen based on exogenous gonadotropins followed by pulsatile gonadotropin-releasing hormone was attempted in order to induce ovulation in a group of patients with polycystic ovarian disease. The women were selected on the basis of previous unsuccessful treatment with clomiphene citrate, gonadotropin and pulsatile gonadotropin-releasing hormone used separately. At our first attempt at application of this new approach, in all patients follicular growth was recorded and ovulation was induced with exogenous chorionic gonadotropin, without hyperstimulation. Two clinical pregnancies were established. Retrospective hormonal evaluation showed the presence of two premature luteinizations. Pulsatile gonadotropin-releasing hormone administration following follicular recruitment with exogenous gonadotropin may therefore be considered an effective therapy for polycystic ovarian patients resistant to conventional treatment.
