The Male Reproductive System

The male reproductive system includes external (penis, scrotum, epididymus, and testes) and internal (accessory) organs.

The purpose of the scrotum is to provide the testes with a chamber of appropriate temperature for optimal sperm production.

The testis is homologous to the ovary in that it produces the male gamete (sperm) while the ovary produces the female gamete (egg).

In human males, the penis serves as both a reproductive organ and as a urinal duct.

Testes ducts, which include the seminiferous tubules and vas deferens, are involved in the creation or transportation of sperm.

The accessory sex glands produce seminal fluid and clean and lubricate the urethra.
