Trichomonas infections in men.

Trichomonas vaginalis, a common pathogen in the female genital tract, produces a characteristic clinical picture in women. Less well recognized are the manifestations of Trichomonas infestations of the male genital tract, which include urethritis and chronic prostatitis. Multiple-glass urinalysis and selective use of Trichomonas cultures may improve recognition of this organism in the family practice setting.
