Webb1 dec. 1994 · Inhibins and activins exhibit a broad spectrum of biologic activities, many of which affect the reproductive axis. Within the ovary and testis, the synthesis of the inhibin and activin α and β subunits is regulated by circulating hormones, such as the pituitary gonadotropins, and by diverse paracrine factors. Webb13 apr. 2024 · by Hasini A. 4 min read. The main difference between Sertoli cells and Leydig cells is that Sertoli cells support the development of sperm cells, whereas Leydig cells produce and secrete testosterone. Testis or testicles is the male reproductive organ in humans. The main function of the testes is to produce sperm and androgens.

WebbInhibin B is a dimer of an alpha and a betaB subunit. It is produced exclusively by the testis, predominantly by the Sertoli cells in the prepubertal testis, while the site of … WebbInhibin is produced by Sertoli cells when the sperm count exceeds set limits. The hormone inhibits GnRH and FSH, decreasing the activity of the Sertoli cells. Increased levels of testosterone affect the release of both GnRH and LH, decreasing the activity of the Leydig cells, resulting in decreased testosterone and sperm production.
