Endometrial polyps can affect pregnancy, but it does not mean that conception is impossible. Rather, it means that the chances of becoming pregnant may decrease. Endometrial polyps can affect the lining of the uterus and thereby hinder the implantation of a fertilized egg after the sperm and egg have combined. Even if fertilization and implantation occur in the uterus, miscarriage is more likely to happen. Therefore, when endometrial polyps occur, treatment can be administered based on the size and extent of the polyps. If the condition is mild with few and small polyps that do not affect pregnancy, conception is still possible.
