There are two types of tubal reversal surgery, one is open tubal reversal surgery and the other is laparoscopic tubal reversal surgery. The principle of both procedures is the same, to reanastomize the severed fallopian tubes, and after the anastomosis, as long as the tubes are open, there is a chance of pregnancy again. However, it is important to note that the best time to get pregnant is within one year after the tubal anastomosis. If you are still not pregnant after one year, you need to consider other ways to get pregnant, usually assisted reproductive technology. The narrower the anastomosis, the more likely it is to result in ectopic pregnancy, so if conception occurs normally, a timely examination should be done to determine the location and size of the gestational sac.
