The folds in the vagina of women of childbearing age are mainly due to the relatively high secretion of estrogen in the body, which leads to the appearance of many folds in the vagina, which are clinically well stretched in order to deliver the fetus from the vagina, a normal physiological phenomenon that does not require clinical intervention. Because of the special anatomy of the vagina, it is recommended to keep the vulva clean in daily life, especially during sex and menstruation, because the folds of the vagina can easily hide bacteria, which can multiply when the resistance is low and cause local inflammation of the vagina, so it is very important for women to keep local cleanliness and pay attention to personal hygiene.
