Trichomonas vaginale (TV) is the third most common cause of vaginal infection, after Thrush and Bacterial Vaginosis. It is caused by a tiny parasite and is usually acquired through sexual intercourse. About 50% of women notice no symptoms and it is found during examination, often while investigating for another infection. Typical symptoms that women complain of are a thick, yellow discharge, smell and soreness. Treating TV is important because it can increase the risk of getting another sexually transmitted infection and occasionally causes complications in pregnancy.


TV can be easily seen under the microscope and although difficult to culture, new DNA tests make it easy to identify.


Treatment consists of specific antibiotics and it important that your sexual partners are treated too to prevent reinfection.
