The scrotum is the protective skin pouch which contains the |testes| (testicles). It is located in the groin, on the outside of the abdominal cavity. This positioning allows the testicles to remain at a temperature slightly below body temperature, a critical condition in the development of viable spermatozoa. After puberty, the hair begins to grow on the scrotum and nearby skin. This pubic hair remains for the rest of the adult life.
