A vasectomy is a surgery that makes a man sterile. The operation takes 30 to 45 minutes. Your doctor will make one or two very small incisions in your scrotum. Then, through these small openings, your doctor will remove part of each sperm tube. The ends of the tubes that stay in your scrotum will be closed up.

Because the doctor cuts and removes part of the tube that carries sperm from the testicles to the semen, man has no sperm in his semen after vasectomy and can't make a woman pregnant.

This operation is used as a means of contraception in many parts of the world. Generally, the success rate of vasectomy is very high, well over 99%. Like any operation this procedure will not guarantee that you will not get a women pregnant. Abstinence is the only 100% way to avoid this. After vasectomy precautions should be taken against pregnancy until a test shows that sperm is out from his semen. Generally, this test is performed after the patient has had 10-20 post-vasectomy ejaculations

A good thing is vasectomy does not affect production or release of testosterone, the male hormone responsible for a man's sex drive, or other masculine traits, like beard, deep voice, etc. The operation also has no effect on sexuality. Erections, climaxes, and the amount of ejaculate remain the same. No woman can differentiate in bed a man with vasectomy, unless the man himself decides to tell her.

Vasectomies will not protect you from STDs such as Aids, Gonorrhea, syphilis or any other sexually transmitted disease. Safe sex is always important when youre not in a long-term monogamous relationship.

The worst thing comes from the main advantage of vasectomy: it is irreversible. The incapacity to eliminate sperm is permanent. Some men want the vasectomy reversed so they can father a child. But surgery to reconnect the tubes doesn't always work. You shouldn't have a vasectomy until you're sure you won't want to have children in the future. Therefore, the decision to have vasectomy surgery is a very important choice for a man. You must live with the consequences for the rest of your life.
