The normal vaginal secretion of white secretion is leucorrhea, and the white secretion from the female labia may be physiological or pathological. Physiological white discharge is normal leukorrhea. There are many secretory glands in the female reproductive tract, which continuously secrete mucus under the action of ovarian estrogen and progesterone, and the color of the mucus is white, which can become yellowish after oxidation, clinically known as leukorrhea. The leukorrhea is discharged through the vagina by gravity. The labia are located at the lowest part of the female reproductive tract and the leukorrhea eventually collects in the labial area. The amount of physiological leucorrhea secretion is not a lot, there is no redness or discomfort, there is no need for any treatment, you just need to wash your vulva with water frequently, change your underwear often and keep it clean. Pathological leucorrhea is mainly considered to be mycosis vaginalis. In mycosis vaginalis, there will be a large amount of white, tofu-like secretions in the vagina, which can gather in the labia, but the amount is particularly large, making the patient’s entire labia have a large area of white, mostly with local redness, swelling, itching and discomfort of the vulva, which needs to be treated with medication.
