Ectopic pregnancy: A pregnancy that is not in the uterus. The fertilized egg settles and grows in any location other than the inner lining of the uterus. The large majority (95%) of ectopic pregnancies occur in the Fallopian tube. However, they can occur in other locations, such as the ovary, cervix, and abdominal cavity. An ectopic pregnancy occurs in about 1 in 60 pregnancies. Most ectopic pregnancies occur in women 35 to 44 years of age.
An ectopic pregnancy occurs when the fertilized ovum fails to reach the uterus and becomes implanted elsewhere. It is also known as an extra uterine pregnancy (1). This means that the fertilized ovum can be implanted in the uterine tubes, the ovary, the abdomen or the cervix (2). Any factor that slows the passage of the ovum along the tube to the uterus can result in an ectopic pregnancy (3).
