where is the hymen located in the female body
Hymen The hymen is a membrane that surrounds or partially covers the external vaginal opening. It forms part of the vulva, or external genitalia, and is similar in structure to the vagina.[1][2] The hymen does not seem to have a specific physiological function or purpose.[3] In children, although a common appearance of the hymen is crescent-shaped, many shapes are possible. Normal variations of the hymen range from thin and stretchy to thick and somewhat rigid; or it may also be completely absent.[1]
