shaped testes are placed outside of the body in a pouch of skin called the scrotum‚ where they can maintain the optimum temperature for sperm production which is estimated at three degrees which is lower than body temperature. Testes are oval shaped glands which are responsible for the manufacture of sperm the sex hormone testosterone. From each testis‚ sperm is passed through a bent tube called the epididymis for the last stages of maturation. They are stored in the epididymides until they are broken
