      Babies come from fertilised eggs. Eggs are the female reproductive cells while sperm are the male reproductive cells. They only contain half the genetic information of other body cells so that they can combine to have 100% of the genetic information you need in each of your cells. Once the sperm meets the egg and fertilises it, the egg divides to form a ball of cells called an embryo. This attaches to the lining of the mother’s uterus and develops into a foetus. All the oxygen and nutrients that the foetus needs comes from its mother. These are supplied by the placenta which is attached to the foetus via the umbilical cord. It also removes the waste products away from the foetus.

      If this is a human baby, it needs 9 mouths to fully develop. Once it is ready to be born the walls of the uterus contract to push the baby out of its mother’s body and into the world.

      One of the fantastic developments in science and technology, we can now fertilise eggs outside of a womb and artificially place inside a womb – meaning that people who were unable to have children are now able to!
