The 'ball sack' in males refers to the scrotum, which is a protuberance of skin and muscle that contains the testicles and is divided by the septum. The purpose of the scrotum is to keep the temperature of the testes slightly lower than the rest of the body. Although men have two testicles, they only have one scrotum.
