Also, they may experience ectopic pregnancy, which is a condition in which the fetus implants, not in the uteran lining - the body of the uterus - where it should be, but in some other place, and typically that’s in the tubes. One out of ten women have an ectopic pregnancy following PID, which is six times more likely than in the general population. Tubal pregnancy in turn is one of the leading causes of first trimester maternal death in this country, and is a major cause of maternal death worldwide, because when the fetus is growing in the tube, which is affixed in a narrow structure, it will actually burst the tube at a certain point in time and cause fetal hemorrhage and death. The point is that PID is a remarkably morbid condition.
