Vasectomy is the partial or total removal of the vas deferens of man, which are the tubes that carry sperm out of the testes. What it does is clog the channel sperm, and therefore prevent sperm out of the testes. So it is an effective method for birth control, since women can not become pregnant, but is not recommended in the short term, because for a while there remain stored sperm. This is a simple outpatient surgery, in most cases, in which local anesthesia is used. Recovery takes less than a week. After vasectomy, the man can still have orgasms and ejaculate semen.
