When a vasectomy is performed, the vas deferens, the tubes that carry sperm from the testicles to the urethra, are cut, tied, or blocked [1]. After this procedure, the testes continue to produce sperm, but the sperm cannot reach the semen or be ejaculated out of the body. According to Johns Hopkins Medicine, the sperm that are produced after a vasectomy die and are absorbed by the body. The ends of the vas deferens that have been cut are sealed off, and the sperm cannot leak into the surrounding cavity. The absorption of the sperm by the body is a natural process that happens over time, and it does not pose any harm to the body. Therefore, there is no need to worry about the presence of excess sperm in the body after a vasectomy.

To add to the OP reply, mine were cut, tied, and cauterized. And I was still able to get a reversal. But plan on another vasectomy, now…
