Child sexual abuse

I have a fifteen year old daughter who came to me recently and told me my ex-husband (her step father at the time) when she was 6 or 7 years old raped her. She told me he pulled her on top of him and penetrated her with his penis. Being time has passed, is there a physical examination to still tell if she has had any type of intercourse, and how long ago? Is there any way to discover any abnormalities in her physical areas? It has been at least 8-9 years since this happened. Please reply.

If they had intercourse, the hymen is probably broken. But to be sure, ask a gynaecologist.
