Ovarian stimulation during assisted reproduction treatment: a comparison of recombinant and highly purified urinary human FSH

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

Lipoprotein(a) changes during natural menstrual cycle and ovarian stimulation with recombinant and highly purified urinary FSH.

This prospective, randomized, controlled study compared the effects of recombinant human FSH (r-hFSH) and highly purified urinary FSH (u-hFSH HP) on lipoprotein(a) [Lp(a)] concentrations in women undergoing ovarian stimulation. Fifty infertile women were randomly allocated into two equally sized treatment groups (n = 25 per group). Thirty normal ovulation women were recruited as controls. The i...

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...

Recombinant FSH Preparations for Controlled Ovarian Stimulation in Assisted Reproduction: A Comparison of Gonal F and Follistim

were transferred and 247 were cryopreserved; for the control media, from 640 cleaving embryos, 103 were transferred and 255 were cryopreserved. Conclusions: This study represents one of the largest for culture media so far undertaken. Preliminary results indicate that the new sequential media series are as good as, if not better than, the current media being used in one facility. Based on these...

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...
