Trichomoniasis is caused by a microscopic parasite. Trichomonasis is transmitted through sexual intercourse. Trichomoniasis can be prevented by condom use or choosing not to have sex.

Most men with trichomoniasis do not experience symptoms. However, some men may experience irritation inside the penis, mild discharge, or a slight burning after urinating or ejaculating. Some women may experience discharge that is green, yellow or grey, a bad smell, itching in the genital area, pain during sex, or burning when urinating. Trichomoniasis is diagnosed by taking a sample of vaginal or penile discharge and looking at it under a microscope.
