The appearance of leukorrhea in little girls is usually between the ages of 10 and 15. The essence of leukorrhea in women is the vaginal secretion of women, which is mainly composed of secretions from the vaginal mucosa, vaginal glands, and cervical glands. When a woman enters puberty, and the ovaries begin to show significant estrogen secretion, vaginal secretions, also known as leukorrhea, will appear. Because the age at which a woman enters puberty is usually after the age of 10, the appearance of leukorrhea in women is usually after the age of 10. Leukorrhea itself is mucous membrane secretion and glandular secretion, in women who have not entered puberty, there is also a small amount of secretion, only when the body of estrogen is very low, it is difficult to specifically observe. So as long as the little girl does not have vaginal itching, odor, a small amount of leukorrhea is normal.
