Gonorrhoea is caused by bacteria that can infect the mucous membrane (lining) of the vagina, penis, anus and eyes. Women often have no obvious symptoms of gonorrhoea. Men usually suffer from a 'drip' - discharge from the penis. Oral sex can cause an infection in the throat. Even if you have had no symptoms, the infection can have complications such as an inflammation in a man’s testicles or a woman’s fallopian tubes. If the inflammation in the fallopian tubes is left untreated, the woman may later have an ectopic pregnancy or become infertile.
