Trichomonas is a parasite, also called Trichomonas vaginalis, that causes a series of genitourinary infections in women or men because it is usually parasitic in the vagina, labial mucosa, perineum, and ureter in men, the most common of which is causing trichomonas vaginalis. Trichomonas infection of the female genital system usually causes trichomonas vaginitis, which can lead to severe itching of the vulva and frothy or greenish-purulent leucorrhea in women. If left untreated, the infection can become epizootic and lead to a series of diseases such as pelvic inflammatory disease and adnexitis. Trichomonas infection is usually caused by unclean sex, lack of personal hygiene and use of products used by trichomonas patients. The purpose of the treatment is to heal. In men, because of the special structure of the reproductive system, most men do not have any symptoms even if they are infected with trichomonas, but it is necessary to treat both men and women together to avoid cross-infection.
