Number of Years Since Your Vasectomy

The truth about the number of years from vasectomy (obstructive interval) and reversal success.

“But my doctor said a reversal could not work because I am 12 years out?” This is wrong on so many levels.

There are 2 mistakes that doctors incorrectly tell patients about the number of years and their reversal.

Far too often many doctors mistakenly tell their patients that a reversal can’t work because they are too far out from vasectomy. This is not true! We see many success in men from 10 to 42 years from vasectomy.

We have the world record, a successful reversal 42 years from vasectomy, now with a 13 year-old daughter.

We published a paper that shows that yes you may need epididymal bypass surgery (VE) but that this is still successful, just at a 70 to 90% success as compared to the 99.5% success of a vas-to-vas (VV) connection.

Here’s what we showed in a review of almost 2800 reversals – the longer you go from vasectomy the higher the likelihood that you will have developed deeper epididymal blockage and so will need a bypass. There is no way to determine this before your surgery. This levels off at about 22 years from vasectomy.

We found that from 22 year to 42 years, 1/3 will need a VV on both sides, about 1/3 of men will need a VE on both sides, and 1/3 will require a vas-to-vas on one and a bypass on the other. That means that there is still a 2/3 chance of excellent results and 1/3 of very good results, no matter how many years you are from vasectomy.

Does this mean that if I am less than 9 or 10 years it would be fine to go to a doctor that only does vas-to-vas connections? Absolutely not! If you look at the graph you will see that one in 10 men will still need bypasses on both sides. Even at just 3 to 4 years, there are times when we find deeper blockage and so have to perform VE’s. Every paper that addresses this, and every course they say the same thing- if you can’t or won’t do VE, it not fair for the patient to do the reversal. Be wary of the doctors that proudly announce that they only do vas-to-vas connections. Just as bad, be wary of the surgeons that decide what technique you will get based on the number of years instead of what is seen in the vasal fluid.
