"Within human culture, the hymen has great significance for its perceived correlation to female sexual status. For many cultures, the presence of an intact hymen before marriage suggests purity and cleanliness. Outside of weddings and marriage, hymens have also had cultural relevance as the word “hysteria” is derived from womb-fury, which was associated with the hymen."

Really, if that hasn't grabbed your attention, I don't know what will.  Enjoy the fun aquatic ape reference also.
