Patient's question:
NoDoctor's answer:
Born with it, the hymen is located 2~3 centimeters from the vaginal opening. The hymen is a circular, hollow membrane that covers the female vaginal opening, with a thickness of about 1-2 mm. It provides some protection for the vagina, preventing some unclean secretions and bacteria from entering. It is particularly important for unmarried girls. Wish you health.
