How is it possible?

How is it possible that some ladyboys or shemales in the porn industry look so damn much like women? I mean everything - body shape, voice, everything except the obvious. I have seen some shemales that put most women to shame - big round ass, wide hips and tiny waist. I don't get it. I know there are hormones that change things, but come on, can the hormone therapy really change body structure and things to that degree, or am I missing something bigtime?
One more thing. Quite often in a shemale video, the camera zooms in on the area between their balls and their asshole (kinda puffy and a line connecting the two). Is that some kind of surgery? Thanks in advance.
