Luteinizing hormone-releasing hormone for induction of follicular maturation and ovulation in women with infertility and amenorrhea

Abstract

Five patients with primary infertility and secondary amenorrhea who did not respond to clomiphene with a gonadotropin or estrogen surge were treated with 500 mug of luteinizing hormone, follicle-stimulating hormone-releasing hormone (LH-RH), self-administered subcutaneously every 8 hours for 14 days. Of four patients who responded to this treatment, three showed follicular maturation, ovulation, and menses, although the luteal phase was deficient; in the fourth patient, follicular maturation and menses occurred without evidence of ovulation. For their second course of treatment these four patients were given LH-RH with the addition of human chorionic gonadotropin when the urinary estrogen levels indicated follicular maturation. All four patients responded with ovulation, an adequate luteal phase, and menses, without clinical indication of ovarian hyperstimulation. These results suggest that LH-RH may be a better alternative to human menopausal gonadotropin in the treatment of anovulatory infertility.
