comparison of highly purified urinary versus recombinant fsh: effect on art outcomes in polycystic ovary syndrome
Authors
abstract
background: polycystic ovary syndrome (pcos) is a common cause of ovulatory disorders and infertility with high lh to fsh ratio. in order to prevent further increase of lh and follicle atresia, different regimens for ovulation induction have been recommended using fsh alone. objective: this study was performed in pcos patients to compare art outcomes in cycles induced by fsh alone, using either recombinant or urinary products. materials and methods: in a randomized trial, from 623 patients who underwent down regulation with gnrh analogue in a long protocol, 160 pcos patients were randomly divided into two groups of 80. group a received 150 iu/d recombinant fsh (gonal-f) and group b 150 iu/d urinary fsh (fostimon). results: 33 cases (41.2%) in group a and 36 (45%) in group b achieved clinical pregnancy, which was not significantly different (p=0.67). total number of oocytes retrieved (13.03±5.56 vs. 14.17±4.89, p=0.17), quality and number of embryos (7.42±3.35 vs. 7.63±3.28, p=0.68) and ohss rate were similar in group a compared to group b. endometrial thickness which was 9.66±1.67 mm in group a and 10.36±1.35 mm in group b, showed a significant difference (p=0.004). conclusion: it seems that in pcos patients, both pure fsh products used for controlled ovarian hyperstimulation have similar effects on art outcome and can be used according to availability and patient acceptance without significant difference.

Comparison of highly purified urinary versus recombinant FSH: Effect on ART outcomes in polycystic ovary syndrome
BACKGROUND Polycystic ovary syndrome (PCOS) is a common cause of ovulatory disorders and infertility with high LH to FSH ratio. In order to prevent further increase of LH and follicle atresia, different regimens for ovulation induction have been recommended using FSH alone.

Human Menopausal Gonadotropin versus Recombinant FSH in Polycystic Ovary Syndrome Patients Undergoing In Vitro Fertilization
BACKGROUND We aimed to compare human menopausal gonadotropin (hMG) and recombinant follicle-stimulating hormone (r FSH) with respect to clinical outcomes and the development of ovarian hyperstimulation syndrome (OHSS) for patients with polycystic ovary syndrome (PCOS) treated with in vitro fertilization (IVF). MATERIALS AND METHODS This prospective randomized controlled trial included a total...
full textOvulation induction with urinary FSH or recombinant FSH in polycystic ovary syndrome patients: a prospective randomized analysis of cost-effectiveness.
The aim of this prospective, randomized trial was to compare the clinical results and the cost-effectiveness of urinary FSH (uFSH) and recombinant FSH (rFSH) in ovarian stimulation for intrauterine insemination (IUI) cycles in polycystic ovary syndrome (PCOS) patients. One-hundred and seventy PCOS infertile patients undergoing IUI were enrolled, and protocols of ovarian stimulation with uFSH or...
