Reproductive Steps List An egg is getting ready to leave the ovary. The lining of the uterus is getting thicker. The egg leaves the ovary. This is called ovulation. The egg moves down the fallopian tube to the uterus. when a woman and a man have unprotected vaginal sex, a man’s sperm can go into the woman’s vagina. The sperm goes up into the uterus and fallopian tubes, this can lead to pregnancy. The sperm meets the egg. They join together. This is called fertilisation The fertilised egg moves through the fallopian tube to the uterus. The fertilised egg sticks to the side of the uterus. A baby can then start to grow. If there is no sperm to meet the egg, the egg will not be fertilised. The lining of the uterus comes away. Blood and the lining from the uterus flow out through the vagina as a period (menstruation) The whole cycle begins again for 28-30 days.
