HOW DOES THE MALE REPRODUCTIVE SYSTEM WORK?
The male reproductive tract is made up of the testes, a system of ducts (tubes) and other glands opening into the ducts. The testes (testis: singular) are a pair of egg shaped glands that sit in the scrotum next to the base of the penis on the outside of the body. Each normal testis is 15 to 35ml in volume in adult men. The testes are needed for the male reproductive system to function normally. The testes have two related but separate roles:
- Production of sperm
- Production of the male sex hormone, testosterone.
