The scrotal area is shaved and cleaned with an antiseptic solution.
An incision or puncture is made into the scrotum (the sac containing the testicles).
The vas deferens tubes, one from each testicle, are tied in two places with permanent sutures. The tubes are severed between the ties by:
Cauterization (burning or searing of the tubes)
Cutting
Blocking with clips or clamps
If an incision is made, it is then closed with stitches.
