Truthfully how does a vasectomy feel?and what after affects are there?

vasectomy is done under local anesthesia, a pain less surgery done throe out the world like a minor surgery,we are tying the tubes only for the sucess of the sperm not being present. we are only causing blockage by the Tye which has both cyto depressive effect because of pressure building and absorption of dead protein which may cause an allergy to tissue and normal tissu is affected.buy the time such a reaction to takes place, most of us would have retired from family life.
