GENERAL HISTOLOGY

Detailed explanation-1: -Testes (or testicles)-these are a pair of egg-shaped glands that sit in the scrotum, on the outside of the body. They produce sperm and testosterone, which is the male sex hormone.

Detailed explanation-2: -Testicles (testes) 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-3: -Three hormones are the principle regulators of the male reproductive system: follicle-stimulating hormone (FSH) stimulates spermatogenesis; luteinizing hormone (LH) stimulates the production of testosterone; and testosterone stimulates the development of male secondary sex characteristics and spermatogenesis.

Detailed explanation-4: -The testes synthesize two essential products: testosterone, needed for the development and maintenance of many physiological functions including normal testis function; and sperm, needed for male fertility.
