Trichomoniasis Overview

Trichomoniasis is a sexually transmitted infection (or sexually-transmitted disease, STD) caused by a protozoan (a microscopic parasite), usually found in the vagina and urethral tissues. Although this condition is most often treated in women, trichomoniasis infection in men can also occur (and often has no symptoms).

Trichomoniasis Causes

Trichomoniasis causes a frothy vaginal discharge that may be yellow-green or gray, itching and irritation of the genitals, burning with urination (sometimes confused with a urinary tract infection), discomfort during intercourse, and a foul smell. Because trichomoniasis is a sexually-transmitted disease, symptoms may appear within 4-20 days after exposure. Men rarely have symptoms, but if they do, they may have a thin, whitish discharge from the penis and painful or difficult urination.
