The vagina is pink under normal circumstances. In women of childbearing age, due to the high level of estrogen, there are more folds in the vagina and the surface of the vaginal wall is not smooth to the touch, there are many folds and the vagina stretches very well. After menopause, the vaginal mucosa becomes thinner and the vaginal folds disappear due to the decrease in estrogen levels. It is recommended that women should pay special attention to the local hygiene of the vulva in daily life, wash the vulva every day and pay attention to the hygiene of sexual life for women of childbearing age or menopausal age.
