The whole 'sex verses gender' debate is coming into play here a bit. Sex is strictly biological, and yes, Nadia was certainly born male, in terms of her sex. And some may say that this can never be fully altered.

But 'gender' is far more complicated, it's a social and psychological aspect of someone's personality. Nadia was born male but believed she had a female mind, to the extent in which she felt the need to physically change her body to align her body to her mind. And a mix of surgery and hormones makes her physically appear to be a woman. We know she wasn't born a woman. But she is not a man.

Hope that explains the issue, at least at a superficial level. :S
