1. Pathological leucorrhea: such as inflammatory leucorrhea, leucorrhea caused by tumors and leucorrhea caused by foreign bodies. Leucorrhea is a mixture of vaginal mucosal exudates, cervical glands and endometrial gland secretions, vestibular gland secretions, and labia majora and labia minora sebaceous gland secretions, with the former two being the main ones. Leucorrhea contains vaginal epithelial exfoliated cells, white blood cells and lactobacilli. Leucorrhea can be divided into physiological and pathological types, and their causes and characteristics are different.

After menopause, due to the decline of ovarian function, the decrease of sex hormones in the body, the gradual atrophy of the reproductive tract, the glandular secretion and the exudation of the vaginal mucosa are greatly reduced, resulting in a decrease in leucorrhea. When women are sexually excited, a large amount of vaginal fluid is discharged to lubricate sexual intercourse. In the past, it was believed that sexual excitement was mainly caused by a sudden increase in the secretion of the greater vestibular glands, but now it is believed that a large amount of fluid mainly comes from the increased exudation of the vaginal mucosa. During sexual excitement, the blood vessels in the vaginal wall are obviously congested and dilated, and a large amount of plasma exudate is produced. Gynecological diseases often cause increased leucorrhea, which has become a symptom of the disease, and its amount and characteristics are significantly different from normal leucorrhea.
