NSU: Non-Specific Urethritis

This can be caused by sexual contact with an infected person

Written by spunout


Non-specific Urethritis (NSU) is an inflammation of the urethra, which mainly occurs in men or people with a penis. If left untreated it may cause infertility.

How is NSU transmitted?

NSU is transmitted through sexual contact with an infected person via vaginal and anal sex and skin-to-skin contact. It can also be passed on through the sharing of sex toys.

Symptoms of NSU

Like a lot of STIs, some people may present no symptoms. Others may have some symptoms, which include;

  • Burning sensation when peeing
  • Redness or swelling at the top of the penis
  • If it spreads to the testicles and prostate gland, it can cause pain or swelling
  • If left untreated it can affect male fertility

How to diagnose NSU

In order to get a diagnosis, you will need to visit your GP or your local STI clinic. They will run tests which usually include:

  • A swab of the penis
  • A urine test

How to treat NSU

NSU can be treated with antibiotics which can be prescribed by your doctor.
