Objective: To determine if ovulation and pregnancy could be achieved in a case of amenorrhea, estrogen deficiency, and markedly elevated serum follicle stimulating hormone (FSH) through reduction of the serum FSH by a gonadotropin releasing hormone antagonist. Methods: A 37-year-old woman with hypergonadotropic secondary amenorrhea related to two courses of chemotherapy with alkylating agents and abdominal radiation therapy (Hodgkin’s disease and breast cancer) was treated with cetrorelix in an attempt to induce ovulation by lowering elevated serum FSH and hopefully restore sensitivity of the few remaining follicles by restoring down-regulated FSH receptors. She was monitored with serum estradiol (E2), FSH, luteinizing hormone (LH), progesterone (P) levels and sonography. Results: As the serum FSH dropped the serum E2 rose and peaked at 200 pg/mL after ten days of cetrotide. She conceived in that cycle. A viable ongoing pregnancy with appropriate ultrasound findings was demonstrated 40 days from conception. Conclusion: This is the first case description of successful ovulation and pregnancy following induction of ovulation with the GnRH antagonist cetrorelix. The possibility exists that the ovulation was spontaneous but it seems unlikely. It has been estimated that the chance of spontaneous ovulation and pregnancy in cases of premature ovarian failure is 1:9,200.
