A vasectomy is a safe and effective urologic procedure that renders a man sterile or unable to father a child. This procedure is typically performed in the urologist’s office, but at times can be done as an outpatient at the hospital.

The vas deferens are the tubes that carry the sperm to the penis from the testes. During this procedure, the vas deferens are cut to keep the sperm from traveling to the penis. The testes continue to produce sperm after this procedure but the sperm have nowhere to go, so they die and are absorbed by your body. The prostate continues to make seminal fluid so you will continue to ejaculate, but there will not be any sperm in it.

Patients do not have any changes in hormone levels or male characteristics after this procedure, and erections are typically not affected.

After this procedure, it is important to know that there will still be some remaining sperm in your semen. It is important to use some other form of birth control until your semen has the absence of sperm.

You will be asked to provide two semen specimens post-vasectomy, typically four to six weeks apart to confirm the absence of sperm. This test is generally done after there have been at least 10 to 20 post-vasectomy ejaculations.
