Effects of highly purified urinary FSH and human menopausal FSH on uterine myoelectrical dynamics

Effects of highly purified urinary FSH and human menopausal FSH on uterine myoelectrical dynamics.

The aim of the study was to investigate the effects of urinary follicle-stimulating hormone (FSH) compounds on the electrical activity of myometrium using signal-processing techniques. Thirty animals were involved in the experiment. After two successive normal estrous cycles, 15 of these animals were put into three equal subgroups. Group 1 was the control; animals were given solvent. Groups 2 a...

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

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,...

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

BACKGROUND Urine derived follicle-stimulating hormone (uFSH) contains a higher proportion of acidic isoforms, whereas recombinant FSH (rFSH) contains a higher proportion of less-acidic isoforms. Less-acidic isoforms have a faster clearance, and thus a shorter half-life than the acidic FSH isoforms. The slow clearance of the acidic isoforms has a longer half-life and higher biological activity. ...

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. OBJECTIVE This study was performed in PCOS patients to compare ART outcomes in cycles induced by FSH alone, using either...
