To determine prevalence of lymphogranuloma venereum among men who have sex with men in Germany, we conducted a multicenter study during 2009-2010 and found high rates of rectal and pharyngeal infection in men positive for the causative agent, Chlamydia trachomatis. Many infections were asymptomatic. An adjusted C. trachomatis screening policy is justified in Germany.
