Overview of the Male Reproductive System

Author(s): Center for Educational Outreach, Baylor College of Medicine.

Major Components of the System

The external male reproductive organs are the scrotum and the penis. The internal reproductive organs include gonads that produce sperm and reproductive hormones; accessory glands that release products essential for sperm movement; and ducts that transport the sperm and glandular secretions. 

Within the testes are Leydig cells, which produce testosterone and other sex hormones. The testes also house the seminiferous tubules, where sperm are formed.
