What happens to the sperm that are produced after vasectomy?
The testicles continue to produce the same things after vasectomy as before, namely testosterone and sperm. The testosterone is released into the bloodstream just as before vasectomy. Sperm, however, come to the cut end of the vas and have no place to go. After a short time, sperm are broken down into their component parts (proteins, lipids, DNA…) and recycled for use elsewhere in the body.
