Female vaginal folds are a physiological phenomenon. Female vaginal folds are related to hormone secretion, reproductive age women estrogen secretion is relatively strong, the vaginal wall will appear a lot of irregularly arranged folds, mainly due to the female biochemical layer of cell division hyperplasia produced by the mucosal tissues, with a certain degree of extensibility, can make the vagina rich in elasticity and stretch, so as to carry on the contraction or diastole. Generally, women’s vaginal folds are thread-like, and some women’s vaginal folds are localized raised granulation folds, mainly due to the different ability of women’s biochemical layer cells to divide and proliferate, the biochemical layer cells are inextricably intertwined and produce different degrees of inclination of the concavity and convexity. Therefore, the folds on the inner wall of the female vagina are a normal physiological structure and do not need to worry too much. If any discomfort occurs, it is recommended to go to the hospital in time for regular treatment.
