Vasovasostomy and Vasoepididymostomy (Vasectomy Reversal)


Each year over 500,000 men in the United States undergo a vasectomy and each year 6% of those men undergo a vasectomy reversal.  Reversals are done in an outpatient setting using a surgical microscope.  A general anesthetic is required to assist with the fine dissection and anastomosis of the lumens of the previously occluded vas deferens.  An incision is made on each side of the scrotum to reveal the site of the previous vasectomy.  The occluded segment is removed and the two fresh ends are joined using stitches as thin or thinner than a human hair. 

There are two types of reversal procedures:

  • Vasovasostomy (V-V): The two ends of the vas deferens are sutured to each other directly.  This procedure has a success rate of >90%.
  • Vasoepididymostomy (E-V): The abdominal side of the vas deferens is connected to the epididymis (the small, coiled gland that connects the vas deferens to the testicle).  This requires a more complex technique and is performed when there is extensive blockage on the testicular side of the vas deferens or if secondary obstructions within the epididymis are present following the vasectomy.  This procedure has a success rate of approximately 60-70%.
