It forms part of the vulva, or external genitalia, and is similar in structure to the vagina . The hymen does not seem to have a specific physiological function or purpose . In children, although a common appearance of the hymen is crescent - shaped, many shapes are possible .

The hymen can also stretch or tear as a result of various other behaviors; for example, it may be lacerated by disease, injury, medical examination, masturbation or physical exercise . For these reasons, the state of the hymen is not a conclusive indicator of virginity, though it continues to be considered so in certain cultures . Although the hymen does not regenerate itself after it is torn, it may be surgically restored in a procedure called hymenorrhaphy . </P>
