Vasectomy specialists in Corona. There are a number of male contraception methods out there, but none as effective as the vasectomy procedure. During a vasectomy, the tubes that carry sperm out of the testes are blocked or tied off, leaving the man sterile. While the procedure is nearly 100 percent effective and should be considered permanent, it can be reversed in most cases. Whether you are just seeking information or looking to have a vasectomy or vasectomy reversal, there are qualified urologists in Corona who can help.
