It explained, in an amazing way, how it could be that birth gender did not always win out, and also how a "man" built like a brick house could feel very femme inside, how someone born male could be female in every other way, why some are gay and some are not, ect., ect., ect. It was fascinating, and backed up through scientific research. It cetrtainly made sense, and in a very easy way to SEE, not just theorize.
The tiniest, microscopic change in the size of these glands could cause a big gender identity shift, explaining how people could change in their feelings about themselves over time, or resist society's definition of "male OR female" only labels. And, of course, the clues given by the brain from these glands are filtered through social influences, personal will, lifetimes choices, experiences, and personality.
Just as one identical twin can develop Alzheimers while the other doesn't, these glands, and their minute differences, could also account for one transgendered twin while the other is not.
I have to find that Documentary. It's driving me nuts.
