Why do girls have leukorrhea?

Patient's question:

No

Doctor's answer:

Analysis of the condition: Leukorrhea is a viscous white liquid secreted from the vagina of women, composed of secretions from the Bartholin's glands, cervical glands, endometrial secretions, exudates from vaginal mucosa, and shed vaginal epithelial cells. Leukorrhea contains lactic acid bacteria, lysozyme, and antibodies, which have the effect of inhibiting bacterial growth. During sexual activity, leukorrhea increases, providing lubrication for the vagina, facilitating sexual intercourse.
Generally, leukorrhea increases in amount and becomes thin and transparent during the mid-cycle of menstruation; after ovulation, it becomes thick, cloudy, and less in quantity. Before menstruation and during pregnancy, leukorrhea also increases. In non-primate mammals, it appears during the estrus period.
