For Normal Sperm Development, the Testes Must Be Kept About

Question

For normal sperm development, the testes must be kept about
A) the same temperature as the brain.
B) 1.1°C cooler than core body temperature.
C) 1.1°C warmer than core body temperature.
D) 4.8°C cooler than core body temperature.
E) 4.8°C warmer than core body temperature.

Accepted Answer

The testes must be kept about 1.1°C cooler than core body temperature for normal sperm development. This is why the testes are located outside the body, in the scrotum, which is kept cooler than the core body temperature. Keeping the testes at a slightly lower temperature allows for optimal sperm production and development.
