Male System Scrotum Sac of skin the testis are held in. Sperm production is higher at lower temperatures Testis Produces the sperm and testosterone (the male hormone) Glands These add fluid to the sperm with nutrients. The fluid and sperm is known as semen Penis The penis can swell with blood to cause an erection Urethra Carries urine and sperm out of the body
