In human males, the testes are located in the scrotal sac outside the abdomen, so as to maintain an ideal temperature for the survival of sperms.
Sperms in humans require a very narrow range of temperatures to survive. By being located in the scrotal sac, they can be moved with the help of muscles closer or farther from the body. This movement helps regulate the temperature of the testes, by utilising body heat. The scrotal sac descends from the abdomen while the foetus is still in the womb.
