Persistence of Trichomonas vaginalis serostatus in men over time.

Purpose: Previous epidemiologic studies have observed positive associations between Trichomonas vaginalis (Tv) serostatus and both prostate cancer (PCa) risk and mortality. However, only a few small older studies have examined Tv antibody persistence over time, all of which were composed mainly of female patients. Therefore, we examined Tv antibody persistence over time, as well as intra-individual variability, among middle- to older-aged men in the Southern Community Cohort Study (SCCS).
