Do the presence of multiple old hymenal lacerations at 3,4,9,11 positions and an introitus opening that admits 4 fingers with ease, necessarily indicate sexual intercourse? Also, can a doctor on examination of hymenal injuries accurately date them? If sex was a month before, can doctor know exactly when sex occurred from simply looking at the old hymenal injuries? How quickly would lacerations to a 15 year old s hymen take to heal? Thanks much. TAG
