Infections caused by protozoa of the Trichomonadidae family, especially Trichomonas vaginalis and Tritrichomonas foetus, constitute important sexually transmitted diseases in humans and cattle, respectively. In both cases, proliferation of the parasites in the urogenital cavity of the female induces epithelial lesions, infertility, and even abortion (for a review, see reference 10). In the case of human trichomoniasis, infection of the male urinary tract is well established (10, 11). However, the frequency with which trichomonal infection is responsible for various clinical syndromes such as urethritis, prostatitis, balanitis, and epididymitis remains controversial (11, 21). Parasites have been found in the urethras of about 70% of men who had contact with heavily infected women within the preceding 48 h. However, this percentage significantly decreases after a few weeks, indicating that the male urinary tract inhibits parasite proliferation (21).
