Success Rates – Technical

The following table shows the expected technical success rates for vasectomy reversal based on the time since vasectomy. These numbers are drawn from Dr. Finnerty”s personal experience with over 3500 vas reversals.

Keep in mind that these are statistical averages, meant to give you a general indication of your chances for success with reversal surgery. They are not a guarantee of success for a specific patient, because individual circumstances (such as an individual’s age and health, spousal fertility, surgical findings, etc.) can and do vary widely. Remember also that while technical success is a prerequisite for pregnancy, it is not an assurance of pregnancy.

Vasectomy Reversal Success Rates
Years After Vasectomy % With Sperm Postop
0-3 Years 93%
4-6 Years 90%
7-10 Years 85%
11-15 Years 75%
16-20 Years 50%
Over 20 Years 35-40%

 

The decline in success rates with years after vasectomy is in part a reflection of the greater chance of requiring an epididymal repair when the time after vasectomy is longer. Because epididymal repairs are technically very demanding and have a higher failure rate, the overall success rate therefore declines. Vas-to-vas (VV) repairs performed even 20 or more years after vasectomy can be expected to technically succeed greater than 90% of the time.

However, new techniques of microsurgical epididymal repair (VE) are greatly improving the success rates of this very difficult operation, and success rates on epididymal repairs are now far better than even a few years ago. Because of the recent introduction of these techniques, the resulting improvements in success are not yet fully reflected in the above results.


A little over 5 years ago, my husband and I flew from Chicago to your office to have his vasectomy reversed. We both want you to know how grateful we are -- to you, to your staff, and for your expertise. Since the surgery, we have had Michael (almost 4!) and Mary Jo (10 months) ... We feel it is important for you to know what a difference you made in our lives, and what an awesome grace it was to have you as our surgeon. Words cannot convey how much we appreciate what you have made possible for us -- we will be eternally grateful!
C. & K.P., Chicago
Easter blessings to you and your family from us. We are having a special celebration and invite you to join us -- we celebrate the life of our new daughter.

My wife and I would like to give you and your staff a hearty "thank you" for the professionalism and care given us...following my son''s departure to our heavenly Father. Your calming manner and assurance that we had a reasonable chance at reattaching my vas deferens, which might allow us to get pregnant, was at fruition soon after our stay in Tacoma. 14 days following the procedure, my wife ... had become pregnant!. We lost our first son, and Dr. Finnerty, touched by God, enabled us to have another son ...

We were very excited to learn just before Christmas that the surgery was a success. We saved the news for out kids until Christmas Eve and what a blessing their reaction was, it couldn''t have been a better Christmas present! We do thank you so much for providing your services at realistic fees, we could never have done it had there not been options other than what we found locally.

I am writing to send our heartfelt thanks to you for your expertise. On September 9th, you performed my husband''s procedure. Three weeks later, we conceived our first daughter. She was born exactly 43 weeks post-op. Since then, we have welcomed a son and also another daughter. We''ll always be grateful.

Our child is a true gift from God. God bless you for turning my vasectomy around after 30 years with so much care and love. We will always love you.
J.C., Tennessee
My husband had a vasectomy reversal four and one-half years ago performed by Dr. Finnerty. Three and one half years after, we were able to conceive a child. Our daughter is such a constant joy in our lives.
C.J., California
Thank you again for making possible the blessings God had in store for us in the way of children ...
T.P., Minnesota
We have been so excited about our new son and he has been such a joyous addition to our family ... Thank you so much for your devotion and belief in vasectomy reversal, we have been so blessed by our little guy. Of course, he can never take the place of our daughter who died, but he sure brings new joy to us ... Again, thank you for all you did! We have been so blessed....
M.M., Camas, WA
My husband had his vasectomy nearly 13 years before the reversal, which resulted in the birth of our daughter.
R.B., California
Our family now has 7 blessings, 3 of which you had a very special part in. Thank you!
