The appearance of white objects in the vagina refers to leukorrhea, which is a mixture of exudate from the vaginal mucous membranes, secretion from the glands of the endometrium, secretion from the glands of the cervical canal, and exfoliated epithelial cells. The formation of leukorrhea is very much related to the role of estrogen. Normal leukorrhea is milky white or colorless and transparent, tasteless or slightly fishy. If the leukorrhea is abnormal, it means that it is caused by certain gynecological diseases, such as vaginal inflammation, cervicitis, etc., which may cause leukorrhea, leukorrhea odor, etc., and also cause women to experience vulvar itching, vaginal pain and other conditions.
