All hormones are tightly controlled in males and go as follows.


#GnRH#, or gonadotropic releasing hormone, is a hormone released by the hypothalamus. It triggers for the release of #FSH# and #LH# from the anterior pituitary gland.

#FSH#, or follicle stimulating hormone, targets the testes, specifically, the Sertoli cells. The Sertoli cells stimulate the production of sperm cells.

#LH#, or luteinizing hormone, targets the Leydig cells of the testes to produce and secrete testosterone. Testosterone aids in the secondary male characteristics that give men their distinct features (facial hair, muscle mass, etc.). Testosterone is also important for adequate sperm production. Without it, sperm cells do not mature properly.
