How well does a reverse vasectomy work?

A reverse vasectomy, or vasovasostomy, typically has a success rate of about 50% to 90%, depending on factors such as the length of time since the original procedure and the surgical technique used. Success is often measured by the restoration of sperm in the ejaculate. However, even if sperm is present, there's no guarantee of fertility, as other factors may influence conception. Overall, many men can successfully father children after a reverse vasectomy, but individual outcomes can vary.
