The cribriform hymen is seen –
The hymen is a thin fold of connective tissue, covered by mucous membranes, about 1 mm in overall thickness, situated at the vaginal orifice. 
They are of different types. Cribriform is one of them, characterized by many small holes. 
As a result of sexual intercourse, the hymen is usually torn from posteriorly, with unilateral or bilateral tears extending to the point of its attachment to the vaginal wall. So the presence of hymen most probably indicates virginity.
