=== Non-gonococcal urethritis (NGU) ===
* '''Caused by organisms other than Neisseria gonorrhoeae'''
** '''Chlamydia trachomatis accounts for 15-40% of cases of NGU, with less common causes including Mycoplasma genitalium, Trichomonas vaginalis, adenoviruses, and herpes simplex virus type 1 (HSV-1)'''
* '''Chlamydia'''
** '''Gram-negative'''
** Incubation period: 3-14 days (same as gonorrhea)
* '''Mycoplasma genitalium'''
** Mycoplasmas lack a cell wall and cannot be Gram stained.
** Can become intracellular, which can establish a chronic infection and aid in avoidance of both immune response and antibiotics
** Risk factors in men are young age, sexual intercourse in the past month, and a sex partner with a recent history of STI diagnosis or treatment
* '''Ureaplasma'''
** The evidence for Ureaplasma as a causative agent in NGU is conflicting
* '''Trichomonas vaginalis'''
** Flagellated parasite that exclusively infects the urinary tract
** Common vaginal pathogen but also can cause urethritis in men
