Sterilization can be restored by reversal surgery. The success rate of recanalization in men can be up to 90%. The results of recanalization surgery in women are related to the extent of sterilization injury, anastomosis site, and length of the fallopian tube.
1. Male: After vasectomy, vasectomy recanalization surgery, i.e., vasovaginal-vasectomy anastomosis, can be performed. At present, with the help of optical instruments such as magnifying glasses or surgical microscopes, vasectomy has been widely developed. The success rate of vasectomy can generally reach 90%, and the possibility of obtaining insemination ability again is 70% to 90%.
2. Women: the effect of tubal recanalization surgery is related to the following factors.
(1) The scope of sterilization damage: large damage, adhesions, causing fluid and distortion all affect the success rate of recanalization.
(2) Anastomosis site: tubal isthmus-isthmus anastomosis or jugular-pubic anastomosis is the most effective, and isthmus-pubic anastomosis is the second most effective.
(3) Tubal length: Siber pointed out that the length of tubal anastomosis should not be shorter than 4 centimeters, and those less than 3 centimeters have no hope of pregnancy. It is generally believed that a postoperative tubal length shorter than 4 centimeters will cause the fertilized egg to develop out of sync with the endometrium, resulting in a failure to attach to the uterus.
Those who wish to have their tubes reopened after ligation should go to the hospital and follow the doctor’s instructions.
