What is a vasectomy?
A vasectomy is a procedure that a man can ask to have to
make him sterile. When a vasectomy is done, the two tubes
(vas deferens, or vas) that carry sperm from the testes to
the penis are cut and blocked. A few months after the
vasectomy, the semen (the fluid that is ejaculated during
sex) no longer contains sperm.
There is no change in a man's ability to have an erection
and sexual intercourse after the procedure. The only
difference is that there are no sperm in the semen to cause
pregnancy.
When is it used?
A vasectomy is one of the most effective and safest forms of
birth control. It is done only when a man asks for it. It
should be considered only when a man wants to be
permanently sterile. Vasectomy can sometimes be reversed,
but the reversal procedure is very costly and it is not
always successful.
An alternative is to try other forms of birth control. You
should ask your health care provider about the choices.
How do I prepare for a vasectomy?
The most important preparation is thinking carefully about
the decision to become sterile. Remember that it is
essentially a permanent decision. You should talk with
your partner about this and make absolutely certain that
you do not want to have any more children.
Follow the instructions provided by your health care
provider. Your provider may prescribe a medicine that you
can take before the procedure to help you relax. Be sure
to ask about this. Also ask your provider about the time
needed for recovery after the procedure.
What happens during the procedure?
The vasectomy is done in an outpatient clinic or in the
health care provider's office. It usually takes 15 to
20 minutes.
First, the doctor numbs each side of the scrotum with a
local anesthetic.
One way to do the procedure involves making 1 or 2 small
cuts in the skin of the scrotum. The doctor pulls each
vas through the opening and cuts the vas. A small section
of each vas may be removed. The two ends of each vas are
sealed shut in one of several ways. For example, a stitch,
cautery (burning with a hot wire or electrical current), or
a metal clip may be used. The doctor then puts each vas
back in the scrotum and may close the cuts in the scrotum
with stitches.
Another way to do a vasectomy is called a no-scalpel
vasectomy. The doctor feels for the vas under the skin of
the scrotum and holds it in place with a small clamp. Then
the doctor uses a special instrument to make a tiny puncture
in the skin and stretch the opening so the vas can be cut
and tied. This approach produces very little bleeding. The
punctures heal quickly by themselves, so no stitches are
needed.
What happens after the procedure?
You may go home after the procedure is completed. There may
be some pain in your groin for 3 or 4 days after the
operation. Some blood or yellow liquid may ooze from the
cuts on the outside. The area around the cuts may swell a
bit and turn black and blue.
The first 48 hours after the procedure are crucial to
healing. Generally, a man will feel very good the day
after the procedure, but that does not mean it is time to
go back to normal activities. Resuming normal activities
too soon is likely to cause internal bleeding and lots of
pain. Ask your provider what he or she recommends.
Your provider may advise the following ways to care for
yourself after the procedure:
- Put an ice bag or package of frozen peas on the bandage
over the scrotum after the procedure. Leave the ice on
the area for 30 minutes and then take it off for 30
minutes. Do this off and on for at least 24 hours.
- Rest at home for at least 2 days.
- Avoid all heavy lifting for at least 1 week.
- Wear a jockstrap or tight-fitting underwear to support
the scrotum (testicles) for 4 to 6 weeks.
- Take a pain reliever, such as acetaminophen or
ibuprofen, for any pain after the procedure. Your
provider may prescribe a stronger pain medicine if it is
needed.
- Go back to work as soon as you are able, usually within a
few days.
You may have sex again as soon as you feel able, usually
about a week after the procedure. For 2 to 4 months use
other birth control methods during sexual intercourse,
until your semen test is sperm-free. It takes an average
of 15 ejaculations for all the sperm to be flushed out of
the vas tubes. Ask your health care provider what other
steps you should take and when you should come back for a
checkup and semen tests.
What are the benefits of this procedure?
- Vasectomy is a very reliable method of birth control.
- There are no pills to take or devices to insert for
birth control.
What are the risks associated with this procedure?
- Local anesthesia may not numb the area quite enough and
some minor discomfort may be felt when the cuts are
made. Also, in rare cases, people have an allergic
reaction to the drug used in this type of anesthesia.
- The tissue next to the testes may become swollen.
- There may be bleeding in the scrotum.
- There is a chance that months or years after the
operation sperm may again appear in the semen and
possibly cause a woman to become pregnant. This is why
it is important to check at least 2 semen samples at
your provider's lab to ensure that no sperm are present.
Until the lab confirms that there are no sperm, you must
continue to use some other form of birth control.
- There is a risk of infection or bleeding.
- Rarely, chronic pain in one or both testicles can occur.
Unfortunately, if this complication occurs, it is
usually hard to fix.
