Scrotum

Real World Example

Imagine trying to keep a delicate piece of chocolate from melting on a hot day. Just like how you might place the chocolate in a cooler bag to maintain its integrity, the scrotum acts as a temperature-regulating sac for the testes. The cooler bag, like the scrotum, ensures the chocolate (or the testes) stays at the right temperature to function properly, preventing it from melting (or in the case of the testes, maintaining optimal sperm production).
