At this time, the vaginal mucosa is thin, the wrinkled wall is few, and the acidity is low, so the resistance is poor. The hymen has the protective effect of preventing bacteria from invading the vagina. After puberty, with the development of the ovary, the estrogen in the body increases, the vaginal resistance is strengthened, and the hymen gradually loses its function.

Second: hymen is a hollow membrane covering the outer mouth of the female vagina, about 1-2 mm thick. The positive and negative sides of the membrane are moist mucous membranes.
