There are really none that I know of. Some women have a stronger hymen than others, so, this is not always a good indication. You might just have to tell the truth and take it from there.
I myself do not know of anyway that a dr can prove that a man has not had sex, have you had sex before this? I also beleive that if a girls hymen is intact she is a virgin, but then agin i could be wrong luck jo
