WebIn males, FSH released by the pituitary gland binds to the G-protein-coupled FSH receptor (called FSHR) expressed by Sertoli cells. In these cells, FSH stimulates spermatogenesis through the activation of mitosis and trophic effects, despite the fact that the complex network of signaling pathways is not fully known yet. WebFSH Pituitary hormone. Acts on seminiferous tubules to increase spermatogenesis by stimulating primary spermatocytes to undergo the first division of meiosis and form secondary spermatocytes. Testosterone From interstitial cells. Stimulates the development of secondary spermatocytes into mature sperm. Students also viewed
