Definition Statistics Signs and symptoms Consequences Testing Treatment Prevention Definition Trichomoniasis is caused by the protozoan Trichomonas vaginalis . It is estimated that up to one in five sexually active women will contract trichomoniasis during her lifetime. Both men and women can carry the infection, although symptomatic infection is more common in women. Because trichomoniasis is sexually transmitted, male sexual partners must also be treated, even if asymptomatic and no infection is detected. Signs and symptoms Profuse discharge, often unpleasant in odour.
Colour varies from light grey to frothy yellow-green.
Vaginal and vulval irritation. Usually inflamed cervix, vagina, and opening to the vagina. In men, there are often no symptoms, or those of urethritis. Symptoms can be aggravated by sexual intercourse. Consequences Trichomoniasis does not pose major long-term risks to the reproductive system.
