High Success Rate

Our Success Rates Are Among The Highest

Our Success Rates At The Vasectomy Reversal Center Of America Are Among The Highest Outcomes Nationally.

Dr. David Fenig and Dr. Melissa Mendez are able to provide this high degree of success for their patients even in the most complex cases including re-dos and the more delicate microsurgery called epididymovasostomy. The number of years from vasectomy to vasectomy reversal is not an issue and our microsurgeons have had success performing vasectomy reversals on patients whose vasectomies were performed 40 years ago and even longer.

Outcomes are as important as the number of reversals the microsurgeon performs and their personal success rates reflect their expertise.

How Success And Results Are Really Determined

Here’s a bit of important background that will help you understand how we arrive at a true success rate.

Since the time of the vasectomy, you presumably have been making sperm (assuming there has been no use of testosterone, steroids, radiation, or chemotherapy), which then hit a wall where the vasectomy was done.

Several different things can then happen to the sperm. They can die and get reabsorbed by the body. They can leak out the end of the vas deferens and form a small cyst or spermatocele. Or, they can back up into the epididymis and cause a blockage there. It is important to ascertain that a blockage has not formed in the epididymis, and this is more common the farther out you are from your vasectomy. By examining the fluid from the testicle side of the vas deferens, the microsurgeon can determine if a secondary blockage is likely.

There are two microsurgery procedures that can be performed when doing a vasectomy reversal – the vasovasostomy and the epididymovasostomy – and the success rates for each procedure differs.

Three Factors That Determine Outcomes

  1. 95% Success Rate: If the fluid from the vas is clear and free-flowing and sperm are present in this fluid, the microsurgeon will perform a vasovasostomy. The success rate for this procedure is close to 95 percent, with an associated pregnancy rate of 75 percent.
  2. If the fluid is similar in quality, clear and free-flowing, but no sperm are present, the microsurgeon will still perform a vasovasostomy, but the success decreases to approximately 80 percent.
  3. If the fluid is poor quality, meaning there is no fluid or it is thick and pasty, a blockage in the epididymis has occurred and the microsurgeon will perform an epididymovasostomy, with an average success rate of about 60 percent.

The success rates at the Vasectomy Reversal Center of America are over 90 percent*, which reflects that most patients are able to have vasovasostomies; however, it is important to choose a microsurgeon who can perform an epididymovasostomy in the event this is necessary.
