There are physiological and pathological reasons for the sticky and pasty appearance of leukorrhea: 1. Normal leukorrhea is white and pasty in appearance, with a sticky texture and no obvious odor, which can play a role in lubricating and protecting women’s vagina. 2. The sticky and pasty appearance of leukorrhea, which is mixed with bean curd-like or milk-clot-like leukorrhea, suggests Candida albicans infection, often accompanied by itching and burning in the vagina. The appearance of the leucorrhoea is sticky and pasty, with a yellow or green color, suggesting a possible bacterial vaginosis, gonococcal cervicitis, gonococcal vaginitis and other gynecological inflammatory diseases, often accompanied by a fishy odor, which should be treated with sensitive antibacterial drugs after a clear diagnosis by laboratory tests. Sticky, pasty and with blood, suggesting possible endometrial cancer, cervical cancer and other gynecological malignant tumors, requiring systematic examination for clear diagnosis.
