Nongonococcal urethritis: Nongonococcal urethritis (NGU) is a bacterial sexually transmitted disease that is characterized as an inflammation of the urethra in males. This infection is not caused by gonorrhea, but by other bacteria that could come from many sources such as the mouth or vaginal fluids. NGU can also be caused by allergies or contraceptives.
Symptoms and treatment:
Some common symptoms of nongonococcal urethritis are burning sensations during urination and a discharge from the end of the penis. It is possible for a woman to carry this infection without knowing it, and therefore she could spread it to her sexual partners. Symptoms in women usually include a discharge, itching, and burning during urination. Some women have no symptoms. Even if the symptoms of nongonococcal urethritis disappear after a couple of months, it is possible for the disease to still be present, so treatment should be sought.
