Gonorrhea is a common STD caused by the bacterium N. gonorrhoeae. The usual symptoms in men are burning with urination and penile discharge. Women are asymptomatic half the time or have vaginal discharge and pelvic pain. Infection of the genitals in females can result in pelvic inflammatory disease if left untreated, which can result in infertility. If left untreated, gonorrhea may spread locally causing epididymitis, disseminated infections can result in endocarditis, meningitis or gonococcal dermatitis-arthritis syndrome. Neonatal gonorrheal conjunctivitis can lead to corneal scarring or perforation, resulting in blindness in the neonate.
