The success rates for tubal ligation reversal surgery vary for individuals due to several factors, but post-surgical pregnancy rates typically range between 40 and 85 percent, reports WebMD. Factors that affect the success rate of a given procedure include the type of tubal ligation performed, the age of the patient and the skill of the surgeon performing the surgery.
Tubal ligation procedures are a class of surgical procedures that block or sever a woman's fallopian tubes to prevent her from becoming pregnant, explains Mayo Clinic. Tubal ligation reversal procedures seek to undo the results of the initial tubal ligation and restore fertility. However, the initial type of tubal ligation procedure performed affects the success rate of tubal reversal procedures significantly. The effects of tubal ligation procedures that use clips or rings to pinch off the fallopian tubes are more likely to be successfully reversed than those of ligation procedures that sever or remove portions of the fallopian tubes, while methods that rely specifically on forming scar tissue in the fallopian tubes are rarely reversible. The fallopian tube length remaining in a given individual and the amount of incidental scar tissue resulting from the initial tubal ligation procedure also affect the odds of success of a tubal ligation reversal surgery.
