GENERAL HISTOLOGY

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: -The two testicles (or testes) produce sperm and the male sex hormone testosterone.

Detailed explanation-3: -The testes are where sperm are produced. The testes are linked to the rest of the male reproductive organs by the vas deferens, which extends over the base of the pelvic bone or ilium, and wraps around to the ampulla, seminal vesicle, and prostate. The urethra then runs from the bladder through the penis.

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.

Detailed explanation-5: -There is a system of tiny tubes in the testicles. These tubes, called the seminiferous tubules, house the germ cells that hormones-including testosterone, the male sex hormone-cause to turn into sperm. The germ cells divide and change until they resemble tadpoles with a head and short tail.
