What is non-gonococcal urethritis (NGU)?

NGU is a sexually transmitted disease that refers to an inflammation of a man's urethra.

What causes it?

A number of organisms can cause it.

What are the complications?

NGU may recur. A recurrence may be triggered by excessive friction during sex or masturbation, or drinking too much alcohol.

If inadequately treated or not treated, serious complications may occur although they are rare. These include:

• Inflammation of the testicles
• Reduce fertility
• Reiters syndrome which causes inflammation of the eyes, joints and urethra

How can I prevent it?

Practise safer sex behaviour can reduce the risk of infection:

• Have sex with only one partner who is not infected and who is having sex only with you.
• Use condom properly.

How do I find out if I have NGU?

You need to be examined by a doctor. NGU can be diagnosed by a swab collected from the urethra, or by urine sample.

NGU can be treated with antibiotics. It is important to take all the prescribed tablets; otherwise infection may not be properly cured. Sexual partners who could have been infected should be treated at the same time. If not, you may be infected again.

Sexual intercourse should be avoided until you and your partner(s) have finished all the medication and been treated.

To ensure the infection has been cured, you have to return to your doctor or clinic for a follow-up.
