Fsh testosterone pathway
WebAbstract. It is well established in various experimental models that luteinizing hormone (LH) stimulated testosterone (T) production of Leydig cells is the key endocrine stimulus of spermatogenesis. The role of the other gonadotrophin, follicle-stimulating hormone (FSH), is as yet somewhat unclear given that several clinical conditions and ... WebJun 27, 2006 · Luteinizing hormone (LH) binds to its receptor on the Leydig cell membrane, which is also coupled to the cAMP signaling pathway, to stimulate the production of testosterone de novo from cholesterol. In concert with the actions of FSH, this testosterone is required for optimal sperm production, as well as for sexual function.
