What endocrine glands regulate sexual activity in males? How does this regulation work and what hormones are involved?

Here are the endocrine glands that regulate sexual activity in males: 1) the hypophysis (aka. the pituitary); 2) the adrenal glands; 3) the gonads (testicles). - - - - - - - - - - - - - It's pretty much all about spermatogenesis... - - - - - - - - - - - - - - - - A way to remember the hormones (F - L - T) "Friendly Little Testicles"! 1) FSH (follicle-stimulating hormone) is secreted by the adenohypophysis acts on the testicles, stimulating spermatogenesis (the production of sperm). 2) LH (luteinizing hormone) is very similar to FSH. It is also secreted by the adenohypophysis and also stimulates the production of testosterone by the testicles (again, which stimulates spermatogenesis. 3)Testosterone, acts on several organs of the body. It's responsible for the appearance of secondary male sex characteristics (beard, body hair, deep voice, increase in the muscle and bone mass, maturation of genitalia, etc.). Testosterone also stimulates spermatogenesis.
