Preparing for vasectomy reversal surgery

Reasons for vasectomy reversal

Achieving a pregnancy is obviously by far the most common reason to have a vasectomy reversal - but it is not the only one. Long-term pain following vasectomy, while uncommon, does occur (so called post-vasectomy syndrome). Vasectomy reversal has about a 70% chance or relieving or reducing such pain. However there is a chance there will be no improvement and a risk there will be worsening of pain after vasectomy reversal.


The older you are the more likelihood that you may have some additional medical problem that may influence the safety of surgery or the chance of complications.

Medical history

It is important to be aware of your general state of health prior to any surgical procedure. There are a variety of conditions that may affect the outcome of your operation. Smoking has been shown to reduce fertility by affecting sperm function. Please ensure that I am made fully aware of your past medical history at the time of your pre-operative consultation.

Pre-operative testing

The American Society of Reproductive Medicine position paper on vasectomy reversal states that provided that you are in good general health, "no specific or unique testing is required" prior to your operation.

Indeed preoperative testing for vasectomy reversal has very low sensitivity and specificity, which essentially means that the results of such tests have a high likelihood of producing misleading results. When tests such as ultrasound and sperm antibody testing are used to decide who should and who should not have a vasectomy reversal then this will do harm. Put another way, these tests are much more likely to exclude men from surgery who would ultimately have successful operation than to identify those who will not have success.


It is technically possible to microsurgically reanastomose both vas deferens in the overwhelming majority of cases and the the only way to accurately assess those in which it is not feasible is to surgically explore the vasectomy sites. Ultrasound does not discriminate sufficiently to be useful.

Sperm antibodies

Sperm antibodies are produced after exposure of sperm to the immune system. About 60% of men develop sperm antibodies in their blood following vasectomy. The presence of sperm antibodies in the blood does not accurately predict pregnancy following reversal and so the value of testing for sperm antibodies pre-operatively is both controversial and unproven. The American Society of Reproductive Medicine recommends against performing pre-operative sperm antibody testing.
