In order to be fertilized they must meet the male gametes (sperm) which have arrived after copulation past the cervix in the uterus. The spem then travel up the uterine horns to the oviduct where they meet the oocytes in the AIJ. The fertilized eggs then travel to the uterine horns where they attach to the uterine wall.
