Male External Anatomy
- Glans: The head or tip of the penis which may be circumcised (the foreskin is removed) or uncircumcised (the foreskin is not removed.)
- Scrotum: The soft sac of wrinkly skin that covers, holds and protects the testicles. The scrotum helps the testicles stay at a temperature a little cooler than regular body temperature. This helps with the production and storage of sperm cells. When it's cold, the scrotum becomes wrinkled and brings the testicles closer to the body. When it is warm, the testicles hang lower, and the surface of the scrotum is smooth. The scrotum is usually darker in color than the rest of the skin. Pubic hair can grow on the scrotum.
- Testicles/Testes: Two glands, each about the size of a walnut, located inside the scrotum. Once a boy reaches a certain point in puberty sperm and the hormone testosterone are produced in the testicles. It is normal for one testicle to hang lower than the other.
- Sperm: The male reproductive cell. The sperm contains the male’s genetic information.
