What happens to sperm after a vasectomy?
A. A vasectomy creates a blockage or “dead end” in the scrotal portion of the vas. The sperm get to the point of blockage and can go no further. They age and then die. The sperm degenerate and the body breaks the sperm down into component protein molecules as it does for dead cells elsewhere in the body. These protein molecules are then reabsorbed in the bloodstream and are eliminated.
