Detailed explanation-1: -The bag of skin that holds and helps to protect the testicles. The testicles make sperm. To do this, the temperature of the testicles needs to be cooler than the inside of the body. This is why the scrotum is located outside of the body.

Detailed explanation-2: -The epididymis (ep-uh-DID-uh-miss) and the testicles hang in a pouch-like structure outside the pelvis called the scrotum. This bag of skin helps to regulate the temperature of testicles, which need to be kept cooler than body temperature to produce sperm. The scrotum changes size to maintain the right temperature.

Detailed explanation-3: -The testes are placed outside the body because, they require a lower temperature for sperm production. Testes which is located outside the body provides a temperature 2-3C less than the body temperature.

Detailed explanation-4: -The Male Reproductive System The scrotum is a pouch-like structure that keeps the testicles at the right temperature.

Detailed explanation-5: -For normal sperm development, the testes must be at a temperature slightly cooler than the body temperature. Special muscles in the wall of the scrotum allow it to contract (tighten) and relax, moving the testicles closer to the body for warmth and protection or farther away from the body to cool the temperature.
