Tubal ligation, also known as having your tubes tied or tubal sterilization, is a type of permanent birth control. During a tubal ligation, the fallopian tubes are cut or blocked to prevent pregnancy permanently. A tubal ligation actually disrupts the movement of the egg to the uterus for fertilization and blocks sperm from traveling up the fallopian tubes to the egg. https://brooklyngynplace.com/tubal-ligation/
