Three hundred and sixty-one women were provided government-funded sterilization reversal services with the technique of microsurgery. A large majority of reasons (89.8%) for requesting reversal surgery was a loss of children, and the mean interval between sterilization and reversal was 28.7 months. Two hundred and seven (69.7%) of 297 follow-up cases have experienced term delivery or intra-uterine pregnancy and 5 cases were ectopic pregnancy. The largest number of reversal clients (63.3%) were sterilized by the laparoscopic unipolar coagulation technique and the next largest group (24.2%) was sterilized by the laparoscopic banding technique. The highest pregnancy rate (77.8%) was shown in clients who had undergone laparoscopic banding technique while the lowest (65.9%) was the group of laparoscopic unipolar coagulation. A more than 60% of the clients became pregnant within 6 months of their reversal surgery, with the shortest interval being 1 month, the longest 39 months, and the mean 7.6 months. A large majority of the successful cases, 81.6%, were pregnant within 1 year of their reversal surgery.
361名女性接受了政府资助的显微外科绝育术逆转服务。要求进行逆转手术的绝大多数原因（89.8%）是子女夭折，绝育与逆转之间的平均间隔为28.7个月。297例随访病例中有207例（69.7%）经历了足月分娩或宫内妊娠，5例为宫外孕。接受逆转手术的患者中，采用腹腔镜单极电凝技术绝育的人数最多（63.3%），其次是采用腹腔镜结扎技术绝育的群体（24.2%）。接受腹腔镜结扎技术的患者妊娠率最高（77.8%），而腹腔镜单极电凝组最低（65.9%）。超过60%的患者在逆转手术后6个月内怀孕，最短间隔为1个月，最长为39个月，平均为7.6个月。绝大多数成功案例（81.6%）在逆转手术后1年内怀孕。
