Little girl leukorrhea may be caused by the following reasons: 1, may be because of gynecological inflammation, such as common cervicitis, endometritis, pelvic inflammatory disease, vaginitis, ovarian inflammation or tubal inflammation, etc., when the little girl suffers from these gynecological inflammation, the inflammation can lead to endometrial or vaginal secretion function abnormality, because the leukorrhea is produced by the endometrium, the vagina, or the ovaries and other corresponding organs together. If these organs have gynecological inflammation, it will lead to increased leukorrhea. 2, may be due to endocrine dysfunction, because the female endocrine system has a complex function, especially the endocrine system secretion of estrogen, sex hormones, progesterone and follicle-stimulating hormone, etc., these hormones can play a regulatory role in the formation of leukorrhea, if these hormone levels are abnormal, it will also appear leukorrhea increased.
