American Urological Association Vasectomy Patient Information Form


If you are thinking of having a vasectomy, there are some important things you should know before the vasectomy is done.

Vasectomy is intended to be a permanent form of contraception. There are options for fertility after vasectomy, but they are not always successful and they are expensive. You should not have a vasectomy unless you and your partner are sure that you do not want to have any more children.

Vasectomy does not produce immediate sterility. It takes about 8-16 weeks before you can be sure that you are sterile by having a microscopic examination of your semen

Following vasectomy, another form of contraception must be used until sterility is confirmed by the finding of no sperm or at most rare non-moving sperm on a semen analysis. Your doctor will tell you when he or she thinks the post-vasectomy semen analysis (also known as PVSA) should be done.

Even after sterility is confirmed by exam of the semen , you must understand clearly that vasectomy is not 100% reliable in preventing pregnancy. There is no method of contraception that is 100% certain to prevent pregnancy. Pregnancy occurs in 1 of 2,000 couples even when semen exam after a vasectomy shows no sperm in the semen. The rare pregnancies that occur after vasectomy can occur at any time, even years later.

A second vasectomy is occasionally necessary when the original vasectomy does not produce sterility. The chance that you will need a second vasectomy is less than 1%.

Your doctor will inform you about how long you should not have sex after vasectomy.

Vasectomy does not cause any physical change in sexual performance, function, pleasure, sensation, interest, desire, satisfaction, penile erection, volume of semen or ejaculation.

The options for fertility after vasectomy include vasectomy reversal and sperm retrieval with in vitro

fertilization. These options are not always successful. Overall, about 50% of couples are able to have children with these techniques. Also, before the vasectomy, it is possible to freeze your sperm in a sperm bank. Freezing sperm is expensive, but it gives you a little insurance in case you decide after the vasectomy that you want more children.

The complications of vasectomy which may occur within about one to two weeks after vasectomy are bleeding and infection. Bleeding usually takes the form of blood oozing from the vasectomy incision or a painful collection of blood under the skin at the vasectomy site (called a hematoma.) Active bleeding usually stops by itself; opening the scrotal skin to control bleeding at the vasectomy incision site is rarely needed. Hematomas (collections of blood) usually get absorbed by the body; occasionally hematomas need to be surgically drained. Infections are usually treated with antibiotics. Rarely an abscess due to infection will require surgical drainage. The risk of these complications is 1-2%.

Medical journals report that about 1-2% of men develop significant chronic pain in the scrotal sac after vasectomy. This pain can last for months or years and can even be permanent. Chronic pain in the scrotum after vasectomy is usually treated with non- steroidal anti-inflammatory drugs (NSAIDS), antibiotics or injections of cortisone-like drugs or anesthetic agents. Few men have chronic pain after vasectomy that is severe enough to require additional surgery.

There are many other permanent and non-permanent alternatives to vasectomy. You should discuss other options for contraception with your doctor to decide which method is best for you.

This information sheet is intended to give you the basic information you should know before you decide to have a vasectomy. Your doctor can provide you with more detailed information if you need it.
