Vasectomy Proceedure

This animation shows a vasectomy procedure. A vasectomy is a procedure to cause permanently sterility in a man by preventing the transport of sperm out of the testes. A small incision is made in the scrotum and each vas deferens is tied off and cut apart preventing sperm from being released within the ejaculate. The small skin incision is stitched closed and the surgery does not affect a man's sexual function.
