The "Vas Deferens" is the tube that carries the sperm from your nuts to wherever
That is the tube that gets cut in half and cauterized. Reversals are really common, and he is young enough that there wont be any negative effects.
The goal of a vasectomy reversal is to bypass the point of obstruction. The initial vasectomy causes blockage in the vas deferens, but additional blockage points can occur as well after the vasectomy. During the procedure, we will:
- Identify the level of blockage. To do this, we collect fluid from the vas deferens and examine it under the microscope.
- Analyze the fluid’s color, consistency and contents to determine the type of vasectomy procedure we will do.
- Perform one of two vasectomy reversal procedures:
- Vasovasotomy (VV), where we stitch together the cut ends of the vas deferens
- Vasoepididymostomy (VE), where we create a bypass around the blockage to reconnect the vas to the unblocked epididymis
- The surgery takes between three to four hours and is an outpatient procedure. You do not need to stay overnight in the hospital.
Our male fertility experts successfully perform vasectomy reversal procedures, returning fertility to men who wish to become biological fathers.
