Non-gonococcal urethritis (NGU) is an inflammation of the male urethra (the tube that carries urine from the bladder out of the body) with or without urethral discharge. NGU can be caused by a variety of bacteria, including chlamydia. Less common causes are viruses. It is not caused by gonorrhea.

Most bacteria and/or viruses that cause NGU can be transmitted during oral, vaginal and anal sexual contact

Many people do not experience symptoms. If symptoms occur, they can be:

  • Discharge from the penis
  • Itching, irritation and redness around the tip of the penis
  • Burning with urination
  • NGU is treated and cured with antibiotics.
  • It is important to abstain from any sexual contact during treatment and for 7 days after treatment.
  • Encourage your partner(s) to be tested before any sexual activity.

If untreated, the bacteria causing NGU may lead to epididymitis (an infection of the tubes that store sperm from the testes) and prostatitis (infection of the prostate).


Any infection in the genital area may increase the risk of becoming infected with HIV.

Practicing safer sex, by using latex or polyurethane condoms and/or oral dams for oral, anal or vaginal sex can reduce the risk of Sexually Transmitted Infections and blood borne infections (STBBIs).
