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.
But in an ectopic pregnancy, the egg implants itself in the fallopian tube â which leads from the ovary to the womb. In rarer cases it implants itself in the abdominal cavity or an ovary. Around one in 60 to one in 80 pregnancies are ectopic â and in the vast majority the baby cannot be saved. Often a woman will only realise the pregnancy is ectopic at the first scan between six and ten weeks. Usually it is terminated immediately because of the risks to the mother.
