Question

sperm are protected from body heat by

o a) the scrotum.

o b) athletic supporters.

o c) semen.

o d) circumcision.

Explanation:

The scrotum is an external sac that holds the testes. Sperm production requires a temperature slightly lower than normal body temperature. The scrotum helps maintain this cooler environment by its position outside the body cavity and its ability to adjust its distance from the body (through cremaster muscle action) based on temperature changes. Athletic supporters are just garments for support, semen is the fluid containing sperm, and circumcision is the removal of the foreskin (not related to temperature regulation for sperm).

Answer:

A. the scrotum.
