I watched a National Geographic 'Explorer' program the other night with this title. The subject concerned 'gender variant' individuals. The program was tasteful, had individuals who apparently has 'intersexed' surgery at birth-the show said that 5 or so are done daily nationwide. who knows. A Dr. Tiger DeVore is a therapist who treats those 'inter sexed' individuals.
It was stated that at least 1% of the overall population is transgendered, but maybe this is a low estimate. I agree.
discussions about differences in the hypothalmus in TG males who had post mortem brain studies-same as in genetic females. DNA studies indicate less efficient testosterone , less masculine brains. very interesting.
The show mentioned that gender differences are not aberrant, but natural-part of the "Evolution Rainbow" as an author explained about her book about the animal world.
It was stated that Transgendered are driven by mind, not anatomy. good description of a complex topic.
