Why Do the Testes Descend into the Scrotum

Question

Why do the testes descend into the scrotum?
A)There is not sufficient room in the abdomen.
B)Abdominal temperature is too low to produce hormones.
C)Abdominal temperature is too high to produce viable sperm.
D)There is no known reason.

Accepted Answer

The temperature in the abdominal cavity is too high for testicular tissue to produce viable sperm. By descending into the scrotum, the testes are able to regulate their temperature, which is necessary for the proper development and function of the male reproductive system.
