What you need to know

  • The testes make sperm and sit outside the body so they stay cooler.
  • Sperm are carried in semen from the sperm ducts to the urethra.
  • The ovaries release an egg into the oviduct, where it may meet sperm.
  • If the egg is not fertilised, the uterus lining is shed as a period.
