From the Research
The success rate for a reverse vasectomy, or vasectomy reversal, is approximately 88% in terms of patency rate, as reported in the most recent and highest quality study 1. The success rate of vasectomy reversal can vary depending on several factors, including the time elapsed since the original vasectomy, the surgeon's experience and technique, the patient's age, and whether there were complications from the original vasectomy.
- The time elapsed since the original vasectomy is a significant factor, with higher success rates when the reversal is performed within 10 years of the vasectomy, as noted in 1.
- Other factors influencing success include the patient's age and whether there were complications from the original vasectomy, as discussed in 2 and 3. The procedure involves reconnecting the vas deferens tubes that were cut during the vasectomy, allowing sperm to once again be present in the ejaculate.
- Success is measured in two ways: patency rate (return of sperm to the ejaculate) and pregnancy rate (the couple's ability to conceive naturally), with patency rates typically being higher than pregnancy rates, as other fertility factors may come into play, as reported in 1 and 4. Recovery takes about two weeks, and it may take several months to a year before sperm counts reach levels adequate for conception.
- For men with very long intervals since vasectomy, a more complex procedure called vasoepididymostomy might be required, which has lower success rates, as noted in 2 and 3. It is essential to consider the most recent and highest quality study when evaluating the success rate of vasectomy reversal, as it provides the most accurate and up-to-date information, as seen in 1.
