Leptin and reproductive function in males.

abstract：:Inhibin is a dimeric glycoprotein that suppresses follicle-stimulating hormone (FSH) secretion from the pituitary. Two bioactive forms of inhibin exist, inhibin A and B. The availability of specific immunoassays for each of the isoforms has enabled the study of the individual inhibins and their physiological roles. In...
