Induction of multifollicular growth in patients non responding to clomiphene citrate and gonadotropins or gonadotropins only

Clin Exp Obstet Gynecol. 1995;22(4):315-20.

Abstract

Objective: We aimed at inducing multifollicular recruitment in patients with chronic anovulation-resistant to Clomiphene Citrate (CC) and/or exogenous gonadotropins.

Design: At the II Department of Obstetrics and Gynecology we treated our patients with exogenous gonadotropins and concomitant endogenous gonadotropin suppression obtained by the use of a GnRH analog (Buserelin).

Patients: We studied 14 patients with chronic anovulation due to either hypothalamic dysfunction or polycystic ovarian syndrome.

Measurements: We monitored the follicular growth ultrasonographically from the eighth day of the menstrual cycle, and assessed E2 and LH daily dosage from the tenth day.

Results: With this protocol we obtained 2 or 3 mature follicles, and reached an ovulatory rate of 80.7% and a pregnancy rate of 71.4%. Premature luteinization never occurred, and progesterone increase took place only after human chorionic gonadotropins administration.
