A tubal ligation ("having your tubes tied") is a type of surgery
for women that permanently prevents pregnancy (sterilization). During a tubal
ligation, the fallopian tubes are closed to prevent fertilization; this blocks
the sperms' path to the egg.
The fallopian tubes can be cut, clamped closed, or tied off, or the
ends may be sealed by applying heat (cautery).
