The white discharge on both sides of the labia majora is mainly divided into two cases: the first case, physiological leucorrhoea, after female sexual maturity under the effect of ovarian hormone levels, the female reproductive tract secretion glands will continue to secrete leucorrhoea, which mainly plays the role of lubricating the vagina. The leucorrhea is in a state of constant circulation, with new leucorrhea being produced and also flowing out from the old leucorrhea through the vagina. The leucorrhea that is discharged tends to accumulate between the labia majora and labia minora, so this area tends to appear white, but the leucorrhea is not particularly abundant and the patient has no discomfort. In the second case, pathological leucorrhea, women with vaginal inflammation, especially mycotic vaginal inflammation, can have a large amount of white, thick, curd-like or bean curd-like leucorrhea, and the leucorrhea on both sides of the labia majora can be particularly abundant and sticky.
