Scrotum

Definition

The scrotum is an external pouch of skin and muscle that houses and protects the testes, playing a crucial role in regulating their temperature for optimal sperm production. It contracts or relaxes in response to temperature changes, ensuring the testes remain slightly cooler than the body's core temperature.
