Abstract

Purpose: The main goal in the present study was to compare follicular development and estradiol levels after ovarian stimulation in pituitary suppressed normally ovulating women undergoing IVF, using highly purified urinary follicle stimulating hormone (FSH) (u-FSH-HP) and recombinant FSH (rec-FSH). A secondary variable in our study was embryo implantation potential, which is closely related to appropriate follicular development and oocyte competence. Methods: For the main purpose of this study, 30 IVF patients (group 1) were treated during IVF consecutive cycles, using the same stimulation protocol, with u-FSH-HP in the first treatment study cycle and rec-FSH in the second one. As a control group (group 2) for implantation rates obtained in cycles treated with rec-FSH, 30 additional IVF patients were included who underwent a second IVF attempt again with u-FSH-HP. Results: The total dose of FSH used and ovarian response obtained in termsof estradiol plasma levels and the total number of growing follicles on the day of human chronic gonadotropin (HCG) injection were similar in both treatment cycles in group 1 but better follicular dynamics and oocyte maturity were obtained with rec-FSH. The implantation rate was significantly higher in rec-FSH treated cycles in patients in group 1 than in control women (group 2). Conclusions: rec-FSH is more efficacious than u-FSH-HP when used in the same patient in inducing multiple follicular development in down-regulated cycles as indicated by ovarian performance and oocyte maturity In addition, rec-FSH yields significantly higher implantation rates than u-FSH-HP when used In patients undergoing their second IVF attempt.
