Male sterilization usually requires sterilization surgery, in which both vas deferens are ligated to impede the discharge of sperm. There are several steps, including anesthesia, separation of the vas deferens, ligation, and suturing. 1. Anesthesia: Usually local anesthesia is used to sterilize the surgical area, and then the surgical site is incised. 2. Separation of the vas deferens: the root of the penis on one side is cut open to determine the location of the vas deferens, which is pulled out of the body with surgical instruments and ligated. 3. Ligation: Ligate both ends of the vas deferens, then cut off the vas deferens, suture the incision, and perform the same operation on the other end of the vas deferens. 4. Suture: Return the ligated vas deferens to its place, make the final suture of the wound, and wrap it with gauze. The patient should rest for a week after the sterilization surgery, change the medication in time, have a semen examination in about a month, and consult the doctor in time if there is any abnormality.
