Recombinant follicle-stimulating hormone: gold standard or not?

Meta-analysis on recombinant versus urinary follicle stimulating hormone.

A recent meta-analysis (Daya and Gunby, 1999) on recombin-ant versus urinary follicle stimulating hormone (rFSH versus uFSH) deserves methodological comment. The a priori definition of eligibility criteria for studies to be included in a meta-analysis are central and must be systematic. It was up to the authors to decide whether their search would be extended to include all unpublished studies,...

Bioactive Follicle-Stimulating Hormone

Specific and sensitive in vitro bioassays suitable for measurement of follicle-stimulating hormone (FSH) in small quantities of serum and urine have recently been validated. Comparisons of bioassay (B-FSH) potencies with immunoassay (I-FSH) estimates and chromatofocusing patterns have facilitated new discoveries regarding the regulation of FSH biosynthesis, storage, secretion, serum concentrati...

Luteinizing hormone response to gonadotrophin-releasing hormone in normal women undergoing ovulation induction with urinary or recombinant follicle stimulating hormone.

Oestradiol enhances pituitary sensitivity to gonadotrophin-releasing hormone (GnRH) in normal women, while in women undergoing ovulation induction the putative factor gonadotrophin surge attenuating factor (GnSAF) attenuates the response of luteinizing hormone (LH) to GnRH. To study the relationships between oestradiol and GnSAF during ovulation induction, 15 normally ovulating women were inves...
