Vasectomy reversal is surgery to undo a vasectomy. It reconnects each tube (vas deferens) that carries sperm from a testicle into the semen. After a successful vasectomy reversal, sperm are again present in the semen and you may be able to get your partner pregnant.
Success rates with vasectomy reversal will range from about 40 percent to over 90 percent. Many factors affect whether a reversal is successful in achieving pregnancy, including time since a vasectomy, and partner age.
