Understanding the Male Anatomy (cont.)

Scrotum

The scrotum is a thin sac of skin and thin muscle in which lie the testicles. The scrotum acts as a climate control system, allowing the testicles to be slightly away from the rest of the body and keeping them slightly cooler than normal body temperature for optimal sperm development. The muscles in the scrotum, called the cremasteric muscles, move the testicles slightly within the scrotum depending on the surrounding temperature.
