It has been suggested that high zinc concentrations found in men may prevent Trichomonas vaginalis from being established in the male reproductive tract. In this investigation T vaginalis was readily killed at concentrations of zinc that occur in the prostatic fluid of healthy men (minimum trichomonacidal concentration (MTC) of 6.4 mmol/l). T vaginalis was also shown to be killed by human prost...
