How successful is a tubal reversal at achieving pregnancy?
Rates of subsequent term delivery following a tubal reversal vary. The time between sterilization and reversal does not seem to influence success rates for female sterilization reversal (as it does in men). Success after sterilization reversal depends on the residual tubal length, the method of reversal, the skill of the surgeon, and the fertility of both partners. The results are highest after reversal of occlusion techniques that damage a small segment of the tube such as a tubal clip or ring (75-90%) and lowest after electrocoagulation (50%). The occurrence of ectopic pregnancy after reversal surgery is about 5% – 8% and is likely due to scarring at the site of anastomosis affecting tubal transport of the fertilized egg.
