The scrotum is a sac of skin that hangs from the body at the front of the pelvis, between the legs, and it contains the testicles. The scrotum performs several functions, including:
-
Protecting the testicles: The scrotum helps to protect the testicles from injury and damage.
-
Regulating temperature: The testicles need to be at a temperature that is slightly cooler than body temperature for normal sperm development. The scrotum provides a "climate-control system" that helps to regulate the temperature of the testicles. Special muscles in the wall of the scrotum let it contract (tighten) and relax, which moves the testicles closer to or farther away from the body for warmth and protection.
-
Containing structures: The scrotum contains several structures, including the external spermatic fascia, testes, epididymis, and spermatic cord.
In summary, the scrotum is responsible for protecting the testicles and regulating their temperature, which is essential for sperm production.
