No-scalpel vasectomy was developed in China in 1974 and has been performed in this country since 1988. The procedure prevents the delivery of sperm during intercourse by blocking the vas deferens (sperm duct) in the scrotum. While a traditional vasectomy involves making an incision in the scrotum and stitches, the no-scalpel vasectomy requires only a very small puncture wound and no stitches. This is accomplished by locating the vas deferens under the skin in the upper portion of the scrotum and numbing the area with an injection of anesthetic. The patient feels very little discomfort as the surgeon makes a tiny puncture in the scrotum, draws the vas deferens out with a special instrument, and divides and ties it off.
P.S. Vasectomy is a simple and safe procedure that is better than 99% effective as a male birth control method.
