MICROANATOMY

Detailed explanation-1: -Scrotum-this is a loose bag of skin that hangs outside the body, behind the penis. It holds the testes in place. 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: -When the testes are exposed to FSH from the pituitary, Sertoli cells within seminiferous tubules in the testes produce sperm through meiosis. Immature sperm leave the testes and enter the epididymis where they mature (see Figure 13.7 below).

Detailed explanation-3: -The Testis has following three functions. First, it produces spermatozoa, the male gametes. Second, it synthesizes testosterone, the principal male sex hormone. Third, it participates with the hypothalamus-pituitary unit in regulating reproductive function.

Detailed explanation-4: -Testes. The testes are the primary male reproductive organ and are responsible for testosterone and sperm production.
