Information and Advice Sexually Transmitted Infections Gonorrhoea Gonorrhoea Gonorrhoea is a bacterial STI easily passed on during sex. About 50% of women and 10% of men don't experience any symptoms and are unaware they're infected. In women, gonorrhoea can cause pain or a burning sensation when urinating, a vaginal discharge (often watery, yellow or green), pain in the lower abdomen during or after sex, and bleeding during or after sex or between periods, sometimes causing heavy periods. In men, gonorrhoea can cause pain or a burning sensation when urinating, a white, yellow or green discharge from the tip of the penis, and pain or tenderness in the testicles. It's also possible to have a gonorrhoea infection in your rectum, throat or eyes. Gonorrhoea is diagnosed using a urine test or by taking a swab of the affected area. The infection is easily treated with antibiotics, but can lead to serious long-term health problems if left untreated, including infertility.
