[Advances in the study of trichomoniasis in men]

Trichomoniasis is an important sexually transmitted disease that is associated with increased perinatal morbidity and increased HIV transmission. Infection with Trichomonas vaginalis also results in local urogenital tract symptoms. Standard teaching is that trichomoniasis is an important cause of vaginitis in women, but that male sexual partners experience little or no morbidity. It is worth-while to summarize critical findings in a series of articles. The prevalence of Trichomonas vaginalis in men represents an important consideration in the differential diagnosis of urethritis.
