    This figure shows the different organs in the male reproductive system. The top panel shows the side view of a man and an uncircumcised and a circumcised penis. The bottom panel shows the lateral view of the male reproductive system and the major parts are labeled.

    Figure \(\PageIndex{1}\): Male Reproductive System The structures of the male reproductive system include the testes, the epididymis, the penis, and the ducts and glands that produce and carry semen. Sperm exit the scrotum through the ductus deferens, which is bundled in the spermatic cord. The seminal vesicles and prostate gland add fluids to the sperm to create semen. (CC-BY-4.0, OpenStax, Human Anatomy)



    The testes are located in a skin-covered, highly pigmented, muscular sack called the scrotum that extends from the body behind the penis (see Figure \(\PageIndex{1}\)). This location is important in sperm production, which occurs within the testes, and proceeds more efficiently when the testes are kept 2 to 4°C below core body temperature. The dartos muscle makes up the subcutaneous muscle layer of the scrotum (Figure \(\PageIndex{2}\)).

    This figure shows the scrotum and testes. The left panel shows the external view of the scrotum, the middle panel shows the muscle layer and the right panel shows the deep tissues of the scrotum.

    Figure \(\PageIndex{2}\): The Scrotum and Testes This anterior view shows the structures of the scrotum and testes. (CC-BY-4.0, OpenStax, Human Anatomy)
