What is the success rate of a vasectomy reversal?
The success rate for vasectomy reversal is greater than 95% when sperm are identified at the time of surgery. The chances of finding sperm at the time of vasectomy reversal is determined by two important factors: the time elapsed since the vasectomy and the site of the vasectomy. When the time interval between the vasectomy and the vasectomy reversal is greater than 15 years, the chances of developing a secondary epididymal obstruction is approximately 70%. Also, when the vasectomy is performed low on the vas deferens then these chances are compounded. If sperm are not identified at the time of vasectomy reversal, an epididymovasostomy will be required to reverse your vasectomy. Vasectomy reversal success with epididymovasostomy is 65-70%. Regardless of the amount of time elapsed since the vasectomy, the success rate should be constant and only dependent on the type of surgery that is required.
