Best for adult men who are certain they want to prevent future pregnancies, vasectomy is a permanent and very effective method of birth control. During a brief outpatient procedure, your doctor cuts the tube that carries sperm out of the testicles. When some time has elapsed after the vasectomy, an ejaculation contains no sperm, and the man cannot impregnate a woman.
Sperm form in the testicles and are stored in an area called the epididymis. From there, they travel through tubes called the vas deferentia and mix with other body fluids to form semen. When each vas deferens is cut or blocked, this process is interrupted. The testicles still produce sperm, but it cannot travel through the penis during ejaculation and is simply reabsorbed by the body.
The procedure is usually done in an outpatient clinic or doctor’s office. It is done under local anesthesia and can take as little as ten minutes. A small incision is made, and the two vas deferens tubes are either clipped shut or cut and the ends sealed. The surgery can also be done without a scalpel, using a special tool that eliminates the need for an incision.
After a vasectomy, some sperm still remain stored in the body and can be ejaculated. Therefore, it is important to continuing using other birth control for a time, until your doctor does a follow-up test and verifies that your semen contains no sperm. Until you have a zero sperm count, you could still cause your partner to become pregnant.
Vasectomy is a very low-risk procedure. The most common complication is mild discomfort and swelling of the scrotum, but this can be minimized by resting, applying cold packs, and wearing a support. Many men do not even need medication for pain afterward.
Vasectomy has a 99.85 percent success rate, which is very good. In addition, the few failures that do occur are usually because the couple does not use another birth control method during the first few months when sperm may still be present in the man’s semen. This is why it is important to have follow-up testing to verify that you have a zero sperm count.
No. Vasectomy does not change your ability to have and enjoy sex, because it does not affect your body’s production of testosterone, the male hormone that primarily controls these functions. In fact, some couples find their sex lives improved because they no longer have to be concerned with an unwanted pregnancy.
