Under local anesthesia, a small incision is made on each side of the scrotal skin . The two ends of the vas deferens are found and freed from the surrounding scar tissue.  I do a microsurgical repair of the vas deferens using a Zeiss OPMI-MDM operating microscope utilizing 10-0 nylon suture (much finer than a human hair).  The repair requires 10-12 stitches.  The goal is to create direct and careful alignment of the lumen of the two ends of the vas and a watertight closure.   A sample of fluid from the testicular end of the vas deferens is placed on a glass slide and examined under a laboratory microscope. Since the testicle continues to produce sperm after a vasectomy, the fluid from the vas deferens could contain sperm. There are 3 possible situations that may be encountered when examining the fluid sample. The first and best situation is that the fluid will contain whole sperm.

The second possible scenario, and more common, is that the fluid is thin and contains only sperm parts or no whole sperm. The third is that the fluid is thick, pasty and contains no sperm. This last phenomenon usually means that there is an obstruction called an epididymal blowout. This means that the vas is obstructed at two levels; at the vasectomy site and by rupture of the tube in the epididymis. In addition to the vasovasostomy, a vasoepididymostomy must be performed. The surgeon cannot make this determination by age of vasectomy but only by examination of the semen. Both sites require repair for a successful outcome, and these procedures can be accomplished at the same time. The technique for VE (vasoepididymostomy) is a microscopic invagination of the epididymal tube into the lumen of the vas deferens using 10-0 nylon sutures.  There is not an additional cost if both repairs must be done. 
"For you created my inmost being;
you knit me together in my mother's womb.
I praise you because I am fearfully and wonderfully made."
