No-scalpel vasectomy (NSV) is a commonly used contraceptive method for males. In previous applications of this surgical method, issues such as knot detachment and postoperative recanalization resulted in a reduced contraceptive success rate after vasectomy. This new technique innovatively modifies the ligation procedure during NSV to address knot detachment and postoperative recanalization. Two ligations of the testicular end of the vas deferens and one ligation of the abdominal end are completed before transection of the vas deferens. A fourth ligation of the abdominal end is performed using the suture tails of the third ligature of the testicular end after transection of the vas deferens. The fifth ligation of the abdominal end is performed using the suture tails of the first ligature of the testicular end. These modifications strengthen the ligations and reduce the postoperative recanalization rate. Additionally, the two stumps are gathered together, creating better conditions for a possible vasovasostomy in the future, thereby achieving overall better outcomes with vasectomy.
