vasectomy effectiveness after a decade

What are the odds of a vasectomy reversal working out ten years post-procedure? I got mine done last year. How likely is it to hold up well over that decade-long period?

A vasectomy reversal's success really comes down to the person and how the original surgery was handled. If there were hopes for a future reversal when it was first done, that tends to boost the chances of it working. You should definitely speak with the surgeon who did your vasectomy; they are in the best position to give you an honest and useful assessment.
