Gonorrhea

Gonorrhea is a sexually transmitted infection that is caused by the bacterium Neisseria gonorrhoeae. The usual symptoms in men are a burning sensation with urination and discharge from the penis. Women have no symptoms about half the time or have vaginal discharge and pelvic pain. In both men and women, if gonorrhea is left untreated, it may spread locally, causing inflammation of the epididymis or pelvic inflammatory disease or throughout the body, affecting joints and heart valves.
