Vasectomy is minor surgery to block sperm from reaching the semen that is ejaculated from the penis. Semen still exists, but it has no sperm in it. After a vasectomy the testes still make sperm, but they are soaked up by the body. Each year, more than 500,000 men in the U.S. choose vasectomy for birth control. A vasectomy prevents pregnancy better than any other method of birth control, except abstinence. Only 1 to 2 women out of 1,000 will get pregnant in the year after their partners have had a vasectomy.

What Happens under Normal Conditions?

Both sperm and male sex hormones are made in the paired testes (testicles). The testes are in the scrotum at the base of the penis. Sperm leave the testes through a coiled tube (the “epididymis”), where they stay until they’re ready for use. Each epididymis is linked to the prostate by a long tube called the vas deferens (or “vas”). The vas runs from the lower part of the scrotum into the inguinal canal. It then goes into the pelvis and behind the bladder. This is where the vas deferens joins with the seminal vesicle and forms the ejaculatory duct. When you ejaculate, seminal fluid and seminal vesicles mix with sperm to form semen. The semen flows through the urethra and comes out the end of your penis.

Treatment

Vasectomies are often done in your urologist’s office. But they may also be done at a surgery center or in a hospital. You and your urologist may decide you need to be fully sedated (put to sleep) for the procedure. If you need to be sedated, you may have your vasectomy at a surgery center or hospital. The need for sedation is based on your anatomy, how nervous you are, or if you might need other surgery at the same time.

You’ll be asked to sign a form that gives your urologist permission to do the procedure. Some states have special laws about the type of consent and when you need to sign it.

In the procedure room, your scrotal area will be shaved and washed with an antiseptic solution. Local anesthesia will be injected to numb the area, but you’ll be aware of touch, tension, and movement. The local anesthetic should block any sharp pain. If you feel pain during the procedure, you can let your urologist know so you can get more anesthesia.

Conventional Vasectomy

For a conventional vasectomy, 1 or 2 small cuts are made in the skin of the scrotum to reach the vas deferens. The vas deferens is cut and a small piece may be removed, leaving a short gap between the 2 ends. Next, the urologist may sear the ends of the vas, and then tie the cut ends with a suture. These steps are then repeated on the other vas, either through the same cut or through a new one. The scrotal cuts may be closed with dissolvable stitches or allowed to close on their own.

No-Scalpel Vasectomy

For a no-scalpel vasectomy, the urologist feels for the vas under the skin of the scrotum and holds it in place with a small clamp. A tiny hole is made in the skin and stretched open so the vas deferens can be gently lifted out. It is then cut, tied or seared, and put back in place.

What are the Risks?

Right after surgery, there’s a small risk of bleeding into the scrotum. If you notice that your scrotum has gotten much bigger or you’re in pain, call your urologist at once. If you have a fever, or your scrotum is red or sore, you should have your urologist check for infection. There is a small risk for post-vasectomy pain syndrome. Post-vasectomy pain syndrome is a steady pain that can follow a vasectomy. It isn’t clear what causes this, but it’s most often treated with anti-swelling meds. Sometimes men will choose to have the vasectomy undone to try to stop the pain. Having the vasectomy undone doesn’t always solve the problem.

Studies show men who’ve had a vasectomy aren’t at a higher risk for heart disease, prostate cancer, testicular cancer, or other health problems.
