ectopic pregnancy

n. pregnancy that takes place outside the uterus

An ectopic pregnancy is a complication of pregnancy in which the fertilized ovum is implanted in any tissue other than the uterine wall. Most ectopic pregnancies occur in the Fallopian tube (so-called tubal pregnancies), but implantation can also occur in the cervix, ovaries, and abdomen. The fetus produces enzymes that allow it to implant in varied types of tissues, and thus an embryo implanted elsewhere than the uterus can cause great tissue damage in its efforts to reach a sufficient supply of blood.

A pregnancy that is not in the usual place and is located outside the inner lining of the uterus. A fertilized egg settles and grows in any location other than the inner lining of the uterus. The vast majority of ectopic pregnancies occur in the fallopian tube (95%), 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. A major concern with an ectopic pregnancy is internal bleeding. If there is any doubt, seek medical attention promptly.
