After a vasectomy where does the sperm go?

The production in the testicles is decreased. The sperm in the tube going out and then to the area of the obstructed vasectomy site decomposes and breaks down over time. When I have done vasectomy reversals in patients years after a vasectomy, the most common finding is sperm parts of heads and tails at various stages of the decomposition process.

The sperm is still being produced by the testicles but unable to be in the ejaculate because of the blockage of the vas. The sperm will live, die and be broken down and the small metabolic pieces are carried away in the blood stream to be excreted in the urine and the feces.

The sperm is essentially recycled. Sperm has a lifecycle. If it has not been ejaculated within that lifecycle it is recycled by the body. As the sperm break down the body uses the parts again. There is no significant build up.

Your body slowly consumes it via macrophage degradation.
