The fimbriated hymen has a dentatedor fringe-like margin. The cribriform hymen presents a number of small certain cases of malformation, the hymen is absent. In other cases it closedentirely (imperforate hymen). The hymen is usually ruptured at the first sexual intercourse. In somecases rupture of the hymen amounts to nothing more than stretching, withslight abrasion. In other cases there is distinct tearing, with considerable painand some bleeding. In rare cases there may be persistent and even serious bleed-ing. In some cases the hymen is so rigid or tender as to prevent coitus. Long FLA~ Fig. 477.

Childbirth destroys the hymen as an intact ring. Usually after parturitionthere are only irregular tags of tissue left, the result of tearing and sloughingabout the vaginal entrance.
