The human male reproductive system is adapted for the production of sperms.

Explanation:

Sperm is produced in the testicles which is covered by the scrotum. The production of sperm requires less temperature than the normal body temperature. The scrotum sac helps to regulate the temperature and maintain a cool temperature for the production of sperms. The scrotum sac also regularly changes size to maintain the correct temperature. The scrotum sac shrinks when the body temperature is low/cold and the scrotum sac expands when the body temperature is high.
