The prostate gland also plays a role in the ejaculation process by contracting to propel the semen out of the body during sexual climax.

Testosterone is a male sex hormone that is responsible for the development of secondary sexual characteristics in males, such as facial hair, deep voice, and muscle growth. It also plays a role in sperm production and sex drive.
