title: Ovulation induction with human menopausal gonadotropin versus follicle-stimulating hormone after pituitary suppression by gonadotropin releasing hormone agonist in polycystic ovary disease. A cross-over study.
abstract: Ten patients with polycystic ovary disease (PCOD) had ovulation induction after pituitary suppression by gonadotropin releasing hormone agonist (GnRHa) with GnRHa plus pure follicle-stimulating hormone (FSH) or plus human menopausal gonadotropin (hMG). Duration of the stimulation period and gonadotropin doses were superimposable. A multifollicular response was observed in both treatments. Bioassay and radioimmunoassay of luteinizing hormone, androstanedione and testosterone plasma levels were higher in hMG cycles compared to FSH-treated cycles. No differences was found in FSH and estradiol (E2) plasma concentrations, whereas in hMG-treated cycles the E2/number of follicles and E2/ovarian volume ratios were greater than in the FSH-treated cycles. Clinical results in terms of percentages of ovulation and pregnancies were the same in the two protocols. We conclude that the presence of luteinizing hormone in induction of ovulation in patients with PCOD does not seem to influence follicular recruitment and development, but it may have a role in the enhancement of steroid production.
