Question

Quizplus · Accepted Answer

When the testes are exposed to cool temperatures, the dartos and cremaster muscles in the scrotum contract to bring the testes closer to the body, which helps to maintain a constant temperature for sperm development. This is an example of the thermoregulatory function of the male reproductive system. Testosterone production is not affected by temperature, and while there may be some increase in sperm production in cooler temperatures, the primary response is the contraction of the muscles in the scrotum. Choice E is incorrect, as temperature is a significant factor in sperm development.
