Only women no longer desiring to have children are treated in this manner. Once the lining cells of the uterus are destroyed by the procedure, there is no place for a developing fetus to attach within the uterus. If some cells remain following an endometrial ablation, there exists the possibility of pregnancy occuring. If pregnancy were to occur, termination would most likely be recommended as doctors are concerned that without adequate cells lining the inside of the uterus, the placenta would grow directly into the muscle wall of the uterus and take hold like the roots of a tree. As a result, the placenta would not be able to separate at the time of delivery, and hemorrhage could occur. This procedure is not a form of birth control and another method of birth control must still be used to avoid pregnancy.
