      <Abstract>Vasectomy is one of the most common procedures performed by Urologists worldwide and considered a safe and permanent method of contraception. The risk of conception following vasectomy is postulated to be 1:2000. Early failure is defined as a post operative semen analysis showing persistent motile sperm while late failure is defined as a rejoining of the severed ends of the vas deferens. There are no reports in the literature of recanalization of the vas deferens resulting in motile sperm and pregnancy and then subsequent negative semen analysis without surgical intervention or re-do vasectomy. Our case shows that recanalization can occur late after vasectomy resulting in pregnancy but that the recanalization can be reversed without intervention.</Abstract>
