Non-specific urethritis (NSU)
Non-specific urethritis (NSU) is used to describe inflammation or irritation in the man’s urethra (the tube that carries pee) in the penis when the exact cause isn’t known.
It is very common and is more common among people who are at risk of sexually transmitted infections (STIs) –
- those who are sexually active
- have had unprotected sex
- have new sexual partners who sexual history is unknown
You can help prevent against NSU by wearing condoms during vaginal, anal or oral sex
Non-specific urethritis (NSU) can have different symptoms and in some cases, NSU causes no symptoms.
In men, symptoms can include:
- white or cloudy discharge from the tip of the penis
- a burning sensation when you pee
- the tip of the penis feeling irritated and sore
NSUis most commonly caused by having unprotected (condom-less) sex with someone who has an infection, but it can also be caused by deodorant, soaps and vigorous masturbation.
There is also a link with NSU to chlamydia, so it is best to test for STIs if you have symptoms.
Testing for NSU involves a swab (like a cotton bud) and sample being taken from the end of the penis. You can test for NSU at:
NSU can often be caused by chlamydia so you may be offered tests for other sexually transmitted infections (STIs) too. Treatment is usually by antibiotics. It is important to complete the course and it is best to wait until you and your partner have completed your treatment before having sex.
