|[C17: from Greek: membrane]|
hymen hy·men (hī'mən)
A membranous fold of tissue that partly or completely occludes the external vaginal orifice.
The Greek god of the wedding feast.
Note: An apparently intact hymen is valued in some cultures as proof of virginity in a bride; this “proof,” however, is not accurate. The hymen may appear incomplete in a virgin, and it may appear intact in a woman who has engaged in sexual intercourse.
