The chance of pregnancy after cesarean ligation is very low and is usually rare in clinical practice. The reason is that the fallopian tube is the channel through which the sperm and the egg must meet in order to get pregnant, and the tubal ligation surgery is usually performed by cutting off the abdomen of the fallopian tube and then ligating it, which means that this channel is cut off. This may be because the last ligation was not strong enough and the ligature was not tight enough, which led to the tubal reopening on its own after a long time, which is extremely rare. In addition, with the liberalization of the two-child policy, some women who want to get pregnant again after having their tubes tied can go to the hospital for tubal reversal surgery, and if the reversal is successful, they can get pregnant again. However, it should be noted that even if the tubes are reopened, it is difficult to say whether the pregnancy will definitely be conceived, because there are many factors that affect pregnancy. In conclusion, the chances of pregnancy after cesarean section are very small, but nothing is absolute.
