In the obstetrics and gynaecology departments of major hospitals, about 1 in 10 women who come for consultation because of "excessive leucorrhoea" have a physiological increase in leucorrhoea, or normal cervical mucus and normal shedding of vaginal epithelial cells.

　　Leukorrhoea is actually vaginal discharge. Normal leucorrhoea appears white paste or egg white-like, highly viscous, without fishy odour and other special smells, and the amount is also relatively small, which does not have any impact on life.

　　Under normal circumstances, the skin of the labia is rich in sebaceous glands, which can secrete sebum and moisturise the pubic skin.

　　The vestibular gland, also known as the Bartholin's gland, can secrete a colourless, clear, transparent and slightly acidic fluid, which is mainly used to maintain the moistness of the vestibular mucosa.

　　Don't think that this fluid is sterile; in fact, the fluid that the vagina drains contains a large number of microorganisms. If you look at them under a microscope, you can even find more than ten species of microorganisms, the vast majority of which are anaerobic, with Lactobacillus being equally common and Candida albicans being the most prevalent yeast. Such a variety of bacteria make up the normal vaginal flora that maintains the normal vaginal environment.

　　Cervical mucus, secreted by the cervical glands, is also an important part of the physiological leucorrhoea. It is alkaline, very similar to egg white, and has a certain viscosity like egg white.

　　It is important that the leucorrhoea smells a little acidic Women of childbearing age have glycogen in their vaginal epithelial cells. Lactobacillus will use glucose as a substrate to produce lactic acid through its own metabolism, hence the slightly sour smell of the leukorrhea. Lactobacillus and other vaginal microorganisms work together to form a complex that inhibits the overgrowth of disease-causing organisms through a complex of actions.

　　So for women, excessive vaginal douching is, in a way, undesirable. A little bit of acidity is important for women.

　　Why did the leukorrhea change colour Physiological leukorrhea changes with the ovarian cycle, so that the wind and water turn, mainly by the action of female hormones in the body and pelvic congestion.
