What is Nongonococcal Urethritis?

Urethritis is an infection of the male urethra, or the tube that carries urine from the bladder to the outside of the body. Nongonococcal means it is not caused by gonorrhea. To find out if you have nongonococcal urethritis (NGU), you must be examined by a doctor or nurse and have lab tests done.

NGU is most commonly caused by a bacterial infection, but it may also be caused by a virus. One of the causes, chlamydia, can lead to complications in men and women. See BC HealthFile #08l Chlamydia for more information.

How is it spread?

NGU is spread by having unprotected sex - not using a condom - with someone who is infected with a bacteria or a virus capable of causing NGU, such as chlamydia.

What are the symptoms?

Symptoms in men may include a slight burning feeling when urinating, an itching inside the penis, or a clear to creamy white fluid from the urethra.

Some men with NGU show no symptoms, or mild symptoms that may be unnoticeable. Usually, the symptoms are seen or experienced more in the morning.

What are the complications?

If not treated, chlamydia can cause pain and swelling in one or both testicles and can result in infertility. As well, the bacteria or virus that cause NGU can cause complications in women. Therefore, female partners of men diagnosed with NGU also require treatment.

What is the treatment?

The treatment for NGU is antibiotic pills. The instructions for taking the pills must be followed carefully, and must be taken until all the pills are finished. People you have had sex with, male or female, must also be tested and treated.

Important: Do not have sex until after you and your partner(s) have finished the treatment.

Should I be tested for other sexually transmitted diseases (STDs)?

If you have different sexual partners, or if your partner has different partners, you should also be tested for other STDs including gonorrhea, chlamydia, syphilis and HIV (the virus linked to AIDS). You should also consider getting vaccine shots to prevent hepatitis B infection.

Please remember: The more sexual partners you have, the higher your risk of getting a STD.

Birth control pills

Birth control pills may not work very well when you are taking some antibiotic medicines. Keep taking your birth control pills while taking any medication, and also use a second form of birth control, such as a condom, until your next period after completing the antibiotics.
