Definition of Pregnancy, tubal

Pregnancy, tubal: An ectopic pregnancy that takes place in the Fallopian tube. Tubal pregnancies are due to the inability of the fertilized egg to make its way through the Fallopian tube into the uterus. Most tubal pregnancies occur in women 35 to 44 years of age. Tubal pregnancies account for 95 percent of all ectopic pregnancies. See ectopic pregnancy.
