What Is It?
A vasectomy is a minor surgical procedure that is done to make a man sterile (unable to father children). The procedure is usually done by a urologist, a specialist who deals with the male reproductive system.
A vasectomy cuts or blocks the vas deferens, the tube that carries sperm away from the testicle to be added to semen. There are two vas deferens, one for each testicle on each side. Once the vas deferens are cut or blocked, sperm cannot pass from the place where there are manufactured, the testicle, to the reservoir where semen and prostatic secretions (secretions from the prostate gland) are stored.
