THORAX ABDOMEN AND PELVIS

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. Epididymis-this is a highly coiled tube that lies at the back of the testes.

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

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