Tubal ligation is a permanent method of birth control for women requiring surgery. The fallopian tubes are cut or obstructed with clips, rings, or electrical current. The most common type of female sterilization involves using an instrument called a laparoscope, which is inserted into the abdomen through a small incision.
Because the fallopian tubes are blocked, the sperm and egg cannot meet.
