Vasectomy for men can be divided into forceps vasectomy, direct vision forceps vasectomy, needle vasectomy, each procedure is different and needs to be analyzed specifically. 1. Clamping vasectomy: after anesthesia, use the separating forceps to pierce the inside of the scrotum, use the internal fixation forceps to fix the vas deferens to be raised, and then separate a section of the vas deferens to be ligated at two places of the vas deferens. 2. Vasectomy by direct-vision forceps: the vas deferens is pinched between the fingers, then the vas deferens is separated from the bulge, a section of the vas deferens is excised, and a silk thread is used to perform the ligature in two places. 3. Needle-piercing vasectomy: During the procedure, a silk thread is used, which is applied to the vas deferens and then ligated. It is recommended that men who need to undergo ligation should consult a regular hospital in a timely manner and choose the appropriate ligation method according to their actual situation.
