Question

For efficient sperm production, the testes must be kept how many degrees below core body temperature?

Accepted Answer

D. 2 to 4°C

1. Sperm production (spermatogenesis) is temperature-sensitive and happens outside the abdominal cavity, in the scrotum.
2. This external location keeps the testes cooler than the body's core.
3. The ideal difference as 2 to 4°C below core body temperature.
4. So 2 to 4°C is correct, not the smaller or much larger temperature gaps offered.
