Vasectomies Reversal can be reversed even after very long periods of time Sperm are constantly being produced in men and even after time, there should be viable sperm.
The chances of vasectomy reversal success depend on how much time has passed between the vasectomy and the reversal. Over time, additional blockages can form, and some men develop antibodies to their own sperm.
Nationwide vasectomy reversal success statistics are readily available. The most commonly cited article is the report of the Vasovasostomy Study Group which appeared in the Journal of Urology in March, 1991 (J Urol 145:505-511, March,1991; we'll mail you the abstract or you can review or copy the article at your local hospital medical library).
Our office success rates compare favorably with these statistics and our updated results (kept on an Access® database) are immediately available on request. The single most important parameter determining success is the number of years since vasectomy.
Within the first 3 years after vasectomy, reversal results in sperm recovery in over 97% of cases. From 3 to 8 years, about 91%; from 9 to 14 years, about 82%; and beyond 14 years, about 69%. Overall 85%, considering all patients who seek vasectomy reversal.1
Success rates may be better when vasectomy reversal is performed under general anesthesia, in an operating room, and with use of an operating microscope so that our doctor can immediately perform a VE when lower end fluid findings suggest additional blockage upstream from the vasectomy site.
