When discussing the possibility of vasectomy reversal with the urologist, either by “vasovasostomy” or “vasoepididymostomy,” it is important to understand that the biggest factor underlying the success of vasectomy reversal is the length of time since the original vasectomy was performed. The more time that has elapsed since the procedure, the less likely that fertility can be restored. Some research shows that men undergoing vasectomy reversal 15 years or more after a vasectomy will have a lower chance of success than men who do it earlier. Despite this and other factors that may stand in the way, vasectomy reversal is entirely possible. Fifty to seventy percent of men have a child following a vasovasostomy (VV).
P.S. While a “vasovasostomy” creates an opening between the separated ends of each vas deferens to allow the sperm to enter the semen before ejaculation, the more technically demanding “vasoepididymostomy” yields lower pregnancy rates.
