In virgin rupture tears of hymen due to sudden tretching occurs in posterior half of membrane usually at the sides i.e. posterolaterally in 4 or 8O clock or 5 or 7O clock position, or in the midline of hymen 6O clock position. With first intercourse tears usually occur in posterior midline because the hymen lies suspended across a potential space here, whereas anteriorly periurethral tissues buttress the hymen. More than 2 tears are unusual, Semilunar hymen often ruptures on both sides. Annular hymen which nearly closes up the vaginal orifice may suffer several hymenal lacerations indicate first sexual intercourse. One deep V shaped clefttear at 6 0 clock or a number of clefts usually in posterior haft hymen membrane indicate passage of any object through hyme orifice which is larger its original opening.
