Microsurgical tubal anastomosis: a controlled trial in four Asian centers

An international program to determine the reversibility of female sterilization in Asia using microsurgical technique was established in 1980. One hundred eleven of 219 patients (51%) conceived following tubal anastomosis; of these, 79 delivered living children. The overall cumulative probability of conception at the end of follow-up, as determined by life-table analysis, was 63%. A decreased pregnancy rate was associated with anastomosis of tubes sterilized by electrocautery methods.
