Although tubal ligation is considered a permanent means of preventing pregnancy, it can be reversed by a procedure known as a tubal ligation reversal, according to the American Pregnancy Association. This procedure involves restoring the functionality of the Fallopian tubes. The reversal procedure is successful in 25 to 80 percent of cases, but it does increase the chance of a woman becoming pregnant in her tubes, which is known as an ectopic pregnancy.
During a tubal ligation reversal procedure, the Fallopian tubes are untied, reconnected or reopened, which allows sperm through to fertilize the egg, according to WebMD. Whether a woman is a candidate for the procedure depends on her age, the type of tubal ligation that was performed, the overall health of the woman and the health of her ovaries, Fallopian tubes and uterus. In particular, the length of the remaining Fallopian tubes is important, since they will affect the success of the procedure. Women seeking the procedure who are younger than 40 and had the procedure during the postpartum period are good candidates.
The procedure is typically performed on an outpatient basis with the use of a laparaoscope, notes WebMD. This allows the surgeon to use minimally invasive techniques to restore the functionality of the tubes.
