How do the scrotal muscles help maintain temperature homeostasis of the testes?
When the body temperature (or external temperature) is high the scrotum muscles relax allowing the testes to hang lower and farther away from the warmth of the body wall. This causes testicular temperature to drop when the external temperature is cold, the scrotal muscles contract to draw the testes closer to the body wall.
