P-229. A prospective and randomized study of ovarian stimulation for ICSI with recombinant FSH versus highly purified urinary FSH

Recombinant human FSH versus highly purified urinary FSH: a randomized study in intrauterine insemination with husbands' spermatozoa.

A randomized trial was carried out comparing recombinant FSH (rFSH) and highly purified urinary FSH (uFSH) in intrauterine insemination (IUI) with husbands' spermatozoa. A total of 45 women received rFSH (139 cycles), while 46 women received uFSH (155 cycles). The starting dose was 150 IU/day s.c., beginning on the second day, and on days 6-7 the dose was adjusted according to ovarian response,...

Highly purified hMG versus recombinant FSH in ovarian hyperstimulation with GnRH antagonists--a randomized study.

BACKGROUND Highly purified hMG (hp-hMG) has recently shown better cycle outcome than the recombinant FSH (rFSH) when compared in GnRH agonist long protocol cycles. However, they have not yet been compared in GnRH antagonist cycles. METHODS A RCT comparing the ongoing pregnancy rate (primary end-point) in 280 patients undergoing IVF/ICSI after stimulation with hp-hMG or rFSH controlled with a ...

Efficacy of Highly Purified Urinary FSH versus Recombinant FSH in Chinese Women over 37 Years Undergoing Assisted Reproductive Techniques

Highly purified HMG versus recombinant FSH for ovarian stimulation in IVF cycles.

The objective of this study was to compare the live birth rates resulting from ovarian stimulation with highly purified human menopausal gonadotrophin (HP-HMG), which combines FSH and human chorionic gonadotrophin-driven LH activities, or recombinant FSH (rFSH) alone in women undergoing IVF cycles. An integrated analysis was performed of the raw data from two randomized controlled trials that w...

Suppression of LH during ovarian stimulation: effects differ in cycles stimulated with purified urinary FSH and recombinant FSH.

There has been much debate about the role of luteinizing hormone (LH) during follicle stimulating hormone (FSH)-treated ovarian stimulation for assisted reproduction, where the endogenous LH is suppressed using a gonadotrophin-releasing hormone analogue. The requirement for LH in oestradiol biosynthesis is established, but other effects of 'insufficiency' are less clear, and little attention ha...
