Extragenital Screening in Men Who Have Sex With Men Diagnoses More Chlamydia and Gonorrhea Cases Than Urine Testing Alone.

Data were evaluated to determine the benefit of extragenital screening among men who have sex with men in detecting chlamydia/gonorrhea infections. More than seventy percent of chlamydia infections and >80% of gonorrhea infections would have been missed with urine testing alone in the course of a year. Extragenital testing is critical for identifying sexually transmitted diseases among men who have sex with men.
