Gonorrhoea is a sexually transmitted infection (STI) caused by the bacteria Neisseria gonorrhoeae. It is highly contagious and can be spread by sexual contact. If you have a Gonorrhoea infection, there is an increased risk of catching other STIs.
Gonorrhoea usually causes no symptoms at all at first. Eventually, it can cause Pelvic Inflammatory Disease (PID) and infertility in women, and inflammation of the testicles and prostate in men. In advanced cases, it can also affect the joints and heart valves in both men and women.
