The vaginal mucosa is the local anatomical component of the vagina, mainly located at the outermost part of the vagina, and has many folds that are clinically elastic and allow the delivery of the fetus through the vagina. The vagina is the channel for sexual intercourse, menstruation and delivery of the fetus. Therefore, if the vaginal mucosa becomes inflamed, it may become congested, edematous and painful, resulting in increased and yellowish vaginal discharge or abnormal discharge. In addition, the vaginal mucosa will become thinner and the walls of the vagina will be flattened after menopause due to the decrease of estrogen.
