MICROANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -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-3: -The male gonads, testes or testicles, begin their development high in the abdominal cavity, near the kidneys. During the last two months before birth, or shortly after birth, they descend through the inguinal canal into the scrotum, a pouch that extends below the abdomen, posterior to the penis.

Detailed explanation-4: -Testosterone is the main sex hormone in men. Most testosterone is made in the testes (testicles). Small amounts are also made in your adrenal gland (in the kidney).
