There are two types of surgical procedures for men’s ligation reversal: one way is to disconnect the ligated part and anastomose the vas deferens at the severed end. The other way is to remove the ligated segment and then anastomose the distal vas deferens with the epididymis, by which the sperm in the epididymis will enter the vas deferens and be stored in the seminal vesicles. This procedure is recommended to be performed under a microscope for a higher success rate, and the possibility of anastomotic stricture is less. Sperm discharge is usually possible in two weeks after the surgery. It is recommended that anti-inflammatory treatment must be given after the surgery, and attention must be paid to the wound after the surgery to prevent infection, which may lead to failure of the surgery.
