Contraception

Methods of Contraception: Contraceptive Methods for Either Sex: Sterilization

Vasectomy: After the vas deferens is cut, it is no longer connected to the testicle.

For Men: Vasectomy
The sterilization of a man, called vasectomy, is a relatively simple and safe operation which does not take more than a few minutes in the doctor's office. It involves the cutting and tying of the vasa deferentia (the thin tubes on both sides of the scrotum through which the sperm travels). As a result of the operation, the sperm cells can no longer become part of the ejaculated fluid but are absorbed by the body. This means that the man is now unable to make a woman pregnant. In every other respect, there is no change; erection, orgasm, and ejaculation occur just as before. In other words, a vasectomy does not affect a man's sexual desire or performance, although some sterilized men enjoy sexual intercourse more because they no longer have to worry about causing an unwanted pregnancy.
 Effectiveness: virtually 100 percent.
