You will not normally get pregnant again after a ligation. Ligation is an effective contraceptive measure with a high success rate, and coitus after ligation is virtually unlikely to result in another unwanted pregnancy. Currently, both men and women can undergo sterilization, such as vasectomy for men and tubal ligation for women. Through ligation surgery, the vas deferens or fallopian tubes can be blocked so that the sperm or egg cannot be discharged normally, and therefore the purpose of fertility cannot be achieved. This method is suitable for people who need to be sterilized or are physically unable to have children for some reason. Ligation requires good preoperative preparation and prompt medical attention, as well as routine medical checkups, such as routine blood and urine tests, to make sure that there are no abnormalities in the body, no coagulation disorders, and so on, before ligation can be performed.
