Its role as a cause of proctitis in people with high-risk sexual behaviour has not been properly defined yet but it seems to be less symptomatic than proctitis caused by Chlamydia trachomatis or Neisseria gonorrhoeae. We present a case of a man who has sex with men with proctitis associated with M. genitalium after excluding other infections known to cause STI proctitis.
