Urethritis is not a specific sexually transmitted infection (STI). It is a symptom that is often caused by STIs, such as chlamydia, gonorrhoea, or mycoplasma genitalium (MGen). Sometimes, no specific cause of urethritis can be found.
Urethritis can also be called non-specific urethritis (NSU) or non-gonococcal urethritis (NGU).
