Hymen

Hymen is a thin piece of mucous 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.

Structure

The hymen varies in size, shape, and thickness; it may be smooth or jagged. It is often crescent-shaped, but can also be round or irregular, with one or more holes or slits. The hymen can also be absent from birth.

Development

The hymen develops from the same tissue that forms the vagina and vulva, and is present from birth. The hymen does not seem to have a specific physiological function and has few, if any, nerve endings.

Cultural significance

In many cultures, the hymen is considered a token of virginity and its condition is believed to be a reflection of a woman's morality. However, the hymen can be broken in many ways, including through physical activity or the use of a tampon, and not all women are born with hymens.

Medical examinations

Medical examinations of the hymen can sometimes be used to confirm or deny sexual abuse or rape. However, the reliability of such tests is questionable, as the hymen can be broken in many ways and its condition does not necessarily reflect a woman's sexual activity or history.

Surgery

In some cases, a woman may choose to undergo a hymenorrhaphy, or hymen reconstruction surgery, to restore the hymen.
