How is a vasectomy done?

There are 2 main techniques for performing vasectomy, but all of them block or cut the 2 tubes, called the vas deferens, that carry sperm cells from the testicles:

  • Conventional vasectomy: a physician makes 1 or 2 small cuts in the skin of the scrotum, which has been numbed with a local anesthetic. The vas deferens is cut, and a small piece may be removed. Next, the doctor ties or clips the cut ends and sews up the scrotal incision. The procedure is then repeated on the other side.
  • No-scalpel vasectomy: An improved vasectomy method, devised by a Chinese surgeon, has been widely used in China since 1974. This so-called nonsurgical or no-scalpel vasectomy was introduced into the United States in 1988, and many doctors are now using the technique here.
