Double Antibody Radioimmunoassay for Human Urinary Follicle Stimulating Hormone

Overnight radioimmunoassay of human follicle-stimulating hormone.

A radioimmunoassay procedure for follicle-stimulating hormone in serum has been developed in which the assay mixture is incubated at 37#{176}C for a total of 22 h, rather than at 4#{176}C for 4-7 days. The withinassay coefficients of variation for the 37#{176}C and 4#{176}C methods, respectively, are 7.7% and 5.0%, while the between-assay variations are 13.8% and 9.9%. Comparison of values for ...

Radioimmunoassay for human follicle-stimulating hormone: physiological studies.

Most of the information concerning secretion changes in follicle-stimulating hormone (FSH) in humans has been gained with relatively insensitive bioassays of concentrates of pools of urine. We have developed a sensitive and specific radioimmunoassay for FSH that is 500-1000 times more sensitive than the rat ovarianweight augmentation assay and which is capable of quantifying FSH in small volume...

Follicle-stimulating hormone and human spermatogenesis.

The role of follicle-stimulating hormone (FSH) in the control of spermatogenesis is not well established in any species, including man. We studied the effect of an experimentally-induced, selective FSH deficiency on sperm production in normal men. After a 3-mo control period, five normal men received testosterone enanthate (T) 200 mg i. m. weekly to suppress luteinizing hormone (LH) and FSH, un...

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 It was up to the authors to decide whether their search would be extended to include all unpublished studies,...
