Trichomoniasis in men: old issues and new data

Sex Transm Dis. 1995 Mar-Apr;22(2):83-96.


Background and objectives: Trichomoniasis is common among sexually active women, but its importance as a cause of morbidity among sexually active men remains uncertain.

Study design: The article outlines areas of controversy and presents pertinent new data from case-control and natural history studies.

Results: Trichomonas vaginalis was documented in 11% of 447 men at risk for a sexually transmitted disease. Although 54% of infected men complained of urethral discharge, the discharge was only mild or moderately severe. Elimination of Trichomonas vaginalis was associated with resolution of urethritis.

Conclusions: Trichomonas vaginalis is an important consideration in sexually active men with urethral symptoms or inflammation but with little or no evidence of discharge on physical examination.
