Question

Give reasons for the following

Scrotum remains outside the body of human males.

Answer 1

The two testes lie in the respective scrotal sacs. The scrotum acts as a thermoregulatory organ and provides an optimum temperature for the formation of sperms. The sperms develop at a temperature of 1-3°C lower than the normal body temperature. Hence scrotum remains outside the body of human males.
