Doctor's Notes on Trichomoniasis

Trichomoniasis (commonly referred to as Trich) is a common sexually-transmitted disease. It is caused by an infection with the parasite known as Trichomonas vaginalis. In women it affects the vagina, vulva, urethra, or cervix. In men, trichomoniasis affects the urethra in the penis.

Trichomonas infection may not cause any symptoms or signs, but if a person has the infection, they can still spread it to other people even if they do not have symptoms themselves. When the condition does cause symptoms, the associated symptoms and signs include redness, burning, and itching of the genital areas, pain with urination (dysuria), and an abnormal vaginal or penile discharge that has been described as foul-smelling and gray, green, yellow or white in color.
