My definition of that is not so much chromosomes or whatever being mixed...but rather hormones being mixed and causing masculinity in a female fetus and affecting the way she uses her brain in comparison to other girls because she was androgen washed in the uterus and during critical stages of development not just physically but also psychologically.  Someone said earlier in one thread that one of the programs pointed out the distinct differences between the areas of the brain that a boy uses compared to a girl.  The only "difference" between the development of a girl and a boy from the 11th week of pregnancy and onwards is higher androgen levels.  It also categorically stated that CAH girls play with that leaned towards boys interests than dolls and prams etc.  

So in a nut shell "Intersexed" would kind of sum up this phenomenom as far as I am concerned.  Rather like a boy being exposed to not enough androgens and too much eostrogen having his brain development and anatomical development affected to the point that he is more feminine than masculine don’t ya think?
