A 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 permanently prevent pregnancy.
A tubal ligation disrupts the movement of the egg to the uterus for fertilization and blocks sperm from traveling up the fallopian tubes to the egg. A tubal ligation doesn't affect your menstrual cycle.
A tubal ligation can be done at any time, including after childbirth or in combination with another abdominal surgical procedure, such as a C-section. It's possible to reverse a tubal ligation — but reversal requires major surgery and isn't always effective.
