A vasectomy is an outpatient procedure that takes about 30 minutes. The patient is usually awake, though receives a local anesthetic. We also offer nitrous oxide (N2O), which empowers you to safely control your comfort during in-office procedures, such as a vasectomy. Often referr to as “laughing gas,” N2O will not completely sedate you, but you will be in a state of relaxation.
During a vasectomy, the urologist cuts the two tubes (vas deferens) that sperm travel through on their journey from the testes, which make sperm, to the penis. The ends are sutured, clipped, and/or sealed by heat (cauterized). Two or three stitches close the incision. In some cases, a no-scalpel technique is used.
The sperm, with nowhere to go, are absorbed by the body.
The prostate and seminal vesicle glands (which produce components of semen) continue to make fluids, so the semen looks the same. Also, hormone levels are unaffected, so hair distribution, voice pitch, and sexual drive and sensations are unchanged.
Note, however, that a vasectomy does not prevent sexually transmitted diseases.
