Detailed explanation-1: -The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
Detailed explanation-2: -The hypothalamus and pituitary gland control how much testosterone the testes produce and secrete. The hypothalamus sends a signal to the pituitary gland to release gonadotrophic substances (follicle stimulating hormone and luteinizing hormone). Luteinizing hormone (LH) stimulates testosterone production.
Detailed explanation-3: -In men, LH primarily stimulates testosterone production, while FSH stimulates the production of sperm.
Detailed explanation-4: -Testosterone is the main sex hormone in men. Most testosterone is made in the testes (testicles).
