Proctitis in Men Who Have Sex with Men.

Sexually transmitted infections (STIs) are diseases that are transmitted from one person to another person through acts of vaginal, anal, or oral intercourse. The increased presence of STIs among men who have sex with men (MSM) results in a higher rate of STI-related diagnoses, such as proctitis. Proctitis is a common, but often misdiagnosed condition experienced by MSM who present to primary care, urgent care, and emergency settings.
