Combined gonadotropin-releasing hormone analog and exogenous gonadotropins for ovulation induction in infertile women: efficacy related to ovarian function assessment.
The ovarian function of infertile women with normal menstrual rhythm was investigated by daily plasma hormone (estradiol, progesterone, luteinizing hormone, and follicle-stimulating hormone) analyses throughout the menstrual cycle, and patients were diagnosed as showing a subnormal profile of progesterone in the early luteal phase or as showing no abnormality. Women with oligomenorrhea and elevated luteinizing hormone levels were diagnosed as having polycystic ovary syndrome primarily on the basis of endocrinology. All patients were treated with a gonadotropin-releasing hormone analog to suppress endogenous luteinizing hormone and follicle-stimulating hormone so that ovulation induction with exogenous gonadotropins could be undertaken as in patients with hypogonadotropic hypogonadism. Interference in the process of ovulation by endogenous luteinizing hormone fluctuations was eliminated and pregnancies were achieved. The pregnancy rate in the group with polycystic ovary syndrome was 77% per treatment course (six cycles) while that in the group with subnormal progesterone profiles was 61.5%. Patients showing no abnormality achieved no pregnancy, demonstrating the redundancy of interference with normal ovarian function.
