When women want a permanent form of birth control, the usual way is to have a tubal ligation (or "having their tubes tied"). Tubal ligation is a surgery to cut or tie the fallopian tubes. When the tubes are cut, eggs cannot move along them into the uterus to be fertilized. The surgery is done under a general anaesthetic.
Health Quality Ontario Reviews Hysteroscopic Tubal Sterilization
With hysteroscopic tubal sterilization, a tiny device called a microinsert is put into each fallopian tube through the vagina, cervix and uterus. Scar tissue grows around the microinsert and blocks the fallopian tubes. The procedure can be done in about 10 minutes in a doctor’s office without general or local anaesthetic.
