He's talking about the 2D:4D ratio, which is more a crude estimation of anything than anything, but both males and females generally have shorter index fingers than ring fingers. The theory is merely that males have more significantly shorter index than ring fingers, and this is supposedly due to prenatal testosterone exposure.

If you want my take, if its really that hard that you're judging hip size and fingers from photos to determine their gender, and if that really matters to you, go ahead, believe there's a girl in there. Or a boy. Whatever floats your boat.
