tubal ligation

Tubal ligation is a surgical procedure in which a woman's fallopian tubes are "tied" or ligated. This procedure prevents eggs from being released from the ovaries into the fallopian tubes, where fertilization normally occurs. Tubal ligation is, thus, a contraceptive method and is 99% effective in pregnancy prevention. While tubal ligation is considered a permanent form of birth control, it can be reversed through a microsurgical procedure in which the fallopian tubes are reconnected.
