Trichomonas vaginalis is one of the most common causes of vaginitis (inflammation of the vagina) in women. Symptoms are more common in women than in men.

In the U.S., an estimated 3.7 million people have the infection, but only about 30% develop any symptoms. Trichomonas testing detects the parasite in samples from the vagina or penis to diagnose an infection.Īccording to the Centers for Disease Control and Prevention (CDC), trichomoniasis, which is caused by the infection, is one of the most common, curable sexually transmitted diseases (STDs).

It causes vaginal infections in women and, in men, infections of the urethra, the tube that carries urine from the bladder to outside the body, and inflammation of the prostate (prostatitis). Trichomonas vaginalis is a single cell (protozoan) parasite that cannot be seen by the naked eye (microscopic).
