What is the Success Rate...
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; you can review or copy the article at your local hospital medical library). 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%. Pregnancy rates (without fertility assistance) also drop slowly with time (from about 80% in the 3-year group to 35% in the >15-years group).
