For most women, especially those of childbearing age and younger, estrogen levels in the body are relatively high. Under the stimulation of high estrogen levels, the cervical glands will secrete a large amount of mucus, which is usually called leukorrhea. Leukorrhea is usually normal, no odor, no vulvar scratching, no vulvovaginal pain, the nature of the secretion is white and transparent, and if it dries out it will become powdery, and this situation is normal. Women’s leukorrhea will change with the menstrual cycle. During ovulation, estrogen levels are very high, and under the action of high estrogen levels, the cervical glands secrete a large amount of mucus, which is stretched out and becomes powdery when rubbed. If a woman’s secretion has a strange odor, vulvar itching, etc., she needs to go to the hospital in time for examination and clear diagnosis.
