Question

When the testes are exposed to cool temperatures,

Options:
A) Testosterone production stops
B) There is an increase in sperm production
C) The scrotal septum opens, allowing the testes to share warmth
D) The dartos and cremaster muscles contract to bring the testes closer to the body
E) None of the choices is correct; the testes are not affected by temperature

Answer 1

When the testes are exposed to cool temperatures, d)The dartos and cremaster muscles contract to bring the testes closer to the body.

Step-by-step explanation:

The correct answer is D) The dartos and cremaster muscles contract to bring the testes closer to the body.

When the testes are exposed to cool temperatures, the dartos and cremaster muscles contract. These muscles are responsible for moving the testes closer to the body, which helps to maintain the optimal temperature for spermatogenesis. By bringing the testes closer, they minimize heat loss and prevent damage to sperm production.

For example, when a person is exposed to cold weather, the contraction of these muscles pulls the testes closer to the body, helping to maintain their temperature and ensuring proper sperm production.
