The hymen protects the female vagina, and a broken hymen can lose a natural protective barrier. For women who have not yet reached sexual maturity, their ovaries are not fully developed, their estrogen is low, and their vaginal resistance is weak. The hymen protects the vagina from the invasion of external bacteria and pathogens, and prevents gynecological inflammation. After puberty, the female reproductive organs gradually develop and the vagina becomes resistant to bacterial invasion, and the hymen gradually becomes weaker and loses this role. If a hymen ruptures due to first time sex or strenuous exercise, it is normal and does not need to be treated, as long as the woman pays attention to vulva cleanliness and maintains good personal hygiene, there is usually no inflammatory infection. If there is bleeding after the hymen rupture, it is treated according to the amount of vaginal bleeding. If the amount of vaginal bleeding is not too much, you can continue to observe it closely and it will usually stop on its own without any special treatment, paying attention to perineal cleanliness and hygiene to avoid infection. If the amount of vaginal bleeding is relatively high, persists or shows signs of gradual aggravation, or if there is damage to the vaginal wall, adhesions or other related conditions, you should promptly go to the hospital for relevant examinations and, if necessary, to stop the bleeding or even to repair it surgically with sutures.
