An ectopic pregnancy is a pregnancy that occurs outside of the uterus. Most ectopic pregnancies occur within a fallopian tube. Other, less common locations may include the cervix, an ovary, or the abdominal cavity. This type of pregnancy cannot survive. Only the uterus can support the growth of a fetus and its placenta.
Many ectopic pregnancies occur because the fallopian tube is not functioning normally.

If the pregnancy is in the fallopian tube, the doctor may be able to repair the tube. In severe cases, the fallopian tube may need to be removed.
