What are the methods of male sterilization?

Male sterilization or vasectomy is a permanent contraception.

          During the surgical procedure, the vasa deferentia are cut and tied in order to prevent sperm leaking out whenever of male ejaculation. Therefore, it can prevent the fertilization since there is no sperm entering to female vagina during a sexual intercourse.

           However, male testicles are still producing sperm and testosterone as usual. The vasectomy just makes sperm unable to move through vasa deferentia. After that, the sperm will be decomposed spontaneously by physical process without any danger. (Male sterilization is not an emasculation or removing testicle causing sexual impotence.) Male can produce semen regularly. Nowadays, there are 2 methods of the vasectomy as following:

  1. Conventional Vasectomy

The surgical procedure will be 1 or 2 small cuts on the scrotum skin above the vas deferens. Then leaving a short gap between 2 ends of the vas deferens before cutting and sealing with a suture.

  1. No-Scalpel Vasectomy

The incision is to puncture the scrotum by a medical equipment in order to find the vas deferens. Then cuts and ties the vas deferens. This method creates the smaller wound without a suture. 

 

       The sterilization is not immediately effective once the surgery has been performed. Patient should wait for 4 months approximately and comeback to receive a diagnosis again in order to make sure none of sperm is still remaining inside the vas deferens.
