If you can have children again after ligation, it is mainly because the fallopian tubes are partially reopened, which will allow the sperm and egg to pass smoothly and form a fertilized egg, which will lead to pregnancy in clinical practice. If there is no menstruation after ligation, it is recommended to rule out the possibility of pregnancy in time, because no contraceptive measure is 100%, and there is a possibility that pregnancy may occur. Ligation is clinically the contraceptive method with the lowest pregnancy rate, so it is recommended that if one does not want to have any more children, both spouses can take ligation if they agree. In addition, contraceptive methods include intrauterine device, using condoms and taking birth control pills, all of which are better methods of contraception.
