Tubes are where the real action happens: the sperm fertilizing the egg. Your ovaries create eggs, but it’s too difficult for sperm to travel all the way to your ovaries. So when an egg is ready to be fertilized, one of your ovaries will release it. A fallopian tube catches that egg, and provides a friendly environment for the egg and sperm to meet. Then the fallopian tube will use its hairs and muscles to move the fertilized egg into your uterus.
