Gonorrhea is a sexually transmitted disease caused by the bacterium Neisseria gonorrhoeae. It can also be transmitted from a mother to her baby during birth. Gonorrhea often produces no symptoms.
If symptoms do occur, in men they may include a discharge of pus from the penis and painful urination. In women, there may be a yellowish-green discharge of pus from the vagina, painful urination, and irregular vaginal bleeding.
Gonorrhea may lead to pelvic inflammatory disease in women or inflammation of the prostate or bladder in men.
Treatment with antibiotics usually clears up the infection.
