[Expert assessment of coital injuries from the forensic medicine viewpoint]

A 38-year-old woman was transmitted to hospital with profuse vaginal bleeding. The origin of the vaginal injuries (resulting from "normal" sexual intercourse vs. use of instruments for manipulation in the vagina) was obscure. The wound pattern is presented and the literature on the subject is reviewed with special reference to predisposing factors and genesis of coital injuries. Concerning the wound pattern, reflecting a blunt trauma, a manipulation with a (so far unknown) instrument, but also with finger or hand could not be proved with the required certainty. In the presented case the origin of the vaginal injuries from "normal" sexual intercourse as described by the accused man could not be excluded.
