Tubal ligation is a relatively the safest method of contraception. The failure rate of tubal ligation reported in different studies varies slightly and there is no exact probability.
Tubal ligation is used to prevent sperm and egg from meeting and to achieve contraceptive effect. This is because the umbilical end of the fallopian tube picks up the egg and enters the fallopian tube after a woman ovulates. Sperm enters the woman’s vagina – uterus – fallopian tube, where the sperm and egg meet to form a fertilized egg, which then enters the uterus under the action of tubal chorionic villi and deposits to form a gestational sac.
Tubal ligation failure rates reported in different studies vary slightly and there is no exact probability. Tubal ligation, where the procedure has failed, is considered to be reoperable.
Women with normal menstrual cycles should go to the hospital within 3 to 7 days after the menstrual cycle is cleared for the ligation procedure. Ligation can be performed at the same time as a cesarean section. Ligation can be performed more than 42 days after a normal delivery.
Women with reproductive requirements are prohibited from undergoing ligation. Women with gynecological infections need to be cured before undergoing sterilization.
It is important to go to a regular hospital for the ligation surgery to avoid complications caused by the lack of strict sterilization.
