The only complication of getting pregnant after a tubal ligation is that there is a high likelihood of experiencing an ectopic pregnancy, states the American Pregnancy Association. However, tubal ligation is an effective method of preventing pregnancy, so the chances of getting pregnant are very low. Patients who experience signs of pregnancy after having the surgery in the past should seek medical help.
The chances of becoming pregnant again after a tubal ligation happens to around 5 out of 1,000 women after 1 year, notes WebMD. About 13 out of 1,000 women are likely to get pregnant 5 years following the procedure. Pregnancy may occur if the surgery was performed poorly, the Fallopian tubes grow back again or a new passage forms that enables the egg to reach the tube or if the patient was pregnant during the surgery.
Tubal ligation, also known as "having your tubes tied," is a surgical procedure whereby the gynecologist blocks, ties or cuts the Fallopian tubes, explains WebMD. In a nonsurgical procedure, the doctor places tubal implants in the Fallopian tubes, leading to scarring around the implants that blocks the tubes permanently. Either procedure prevents the traveling of eggs from the ovaries to the Fallopian tubes, where fertilization occurs.
