The normal leucorrhea is white and thin or egg-white thick, with little volume and no fishy odor, suggesting that the leucorrhea is odorless, colorless and watery for many reasons, such as inflammation of the cervix, cervical erosion, cervical nuchal cyst, including dysbiosis of the vaginal flora, which may accompany changes in the leucorrhea. However, in order to exclude HPV infection in the cervix, it will be accompanied by tasteless, colorless and watery leucorrhea. Anti-viral medication will be required.
