I think you are asking "What is a Tubal Ligation?"
A tubal ligation is the ligation or cutting of the fallopian tubes in a female to prevent pregnancy. It is done in the operating room under general anesthesia and is considered a permanent, although not always 100% effective, means of Birth Control.
Also it is sometimes referred to as "tying the tubes" or "having my tubes tied".
Typically, the surgeon will actually remove a portion of the tubes and seal off the ends of the tubes so that there is no longer a passage for the egg to pass through.
It's very rare but it can happen. Tubal ligation has less than a 2% failure rate but if you feel that you may be pregnant you should see a Dr immediately because you are at a much higher risk for ectopic pregnancy.
Tubal ligation, often referred to as "tubaligation," is a surgical procedure for female sterilization that involves blocking or sealing the fallopian tubes to prevent pregnancy. While it can sometimes be reversed through a surgery called tubal reversal, the success of this procedure varies depending on factors such as the method of the original ligation, the woman's age, and overall reproductive health. However, not all women are candidates for reversal, and it does not guarantee restored fertility.
