A vasectomy in five colors…Blue/ the normal path of sperm from the production in the testicle, out the epididymis and into the vas deferens…Black/ the “grain of rice” opening on the scrotal skin over the vas defernes…Red/ the area of the transected vas and the segment removed…Green/ the lumen of the vas which is fulgurated or cauterized on either side of the transected vas…Yellow/the absorbable suture used to both occlude the vas and to seal off small vessels that may cause a delayed hematoma. No wonder that the chances of “growing back together” is less than one in two thousand! And why the dreaded complication of a egg sized knot “hematoma” is seldom seen after a vasectomy performed by Dr. McHugh.
