NSU stands for Non-Specific Urethritis and is a bacterial infection. Only men get this, and it’s an infection of the urethra (where your pee comes from). 

How you get it:  

  • Many cases are thought to be caused by Chlamydia, but sometimes the cause is unknown. 

Symptoms:  

  • Often there are none, but there might be a discharge from the penis or a burning sensation when you pee. 

Treatment:  

  • Antibiotics  

If it’s not treated: 

  • NSU might be a sign of Chlamydia or Gonorrhoea, so the long term effects could be the same as for those.
