If a zygote attaches to the wall of the fallopian tube it is called an ectopic pregnancy. If it continues to grow, it will cause the tube to rupture and the mother to hemorrhage. If left untreated this can lead to death. Ectopic pregnancies have to be terminated because they are never viable and can be life threatening to the mother.

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.
