Some time ago I saw a documentary about a boy who,when he was a baby,somehow suffered major damage to his you-know-what..I think it was the result of an operation gone wrong.The doctors then decided that,given the circumstances,it was best to turn him into a girl and raise him as a girl.Long story short,the guy,interviewed for the documentary,said that he know all along that he didn't want to do girl things and that there was something very wrong with the way he was treated...and that was *before* he understood anything about what happened.IOW,being a boy...or a girl...is innate,at birth,to all kids and only the most disordered individuals attempt to buck that important fact of nature.
In the 1960s, university researchers conducted studies about gender orientation, and these studies were essentially duplicated by the US government in the 1980s.
About halfway through mammalian gestation, a male fetus will secrete a small amount of testosterone, which travels to its brain and tells it, that it is a “male” brain. If the testosterone does not arrive, by default the brain is a “female” brain.
The researchers interfered with this process, creating animals that were physically male but psychologically female, and visa versa. They also tried limiting the hormone to just one brain hemisphere, and came up with animals that would exhibit traits of both genders in mating.
However, they noted even back then, while this was enough to determine animal sexuality, it did not do the same for humans. That is, feminine boys were still mostly sexually attracted to girls, with only the typical number homosexual.
The researchers noted with some concern that female hormone can block testosterone, and plant estrogen was and is being widely used to increase crop yields. Since it is chemically similar to animal estrogen, they worried that it might result in far more feminine male children over time.
Androgynous, though still mostly heterosexual.
Eventually it turned out that females who consumed either male or female hormones prior to pregnancy could influence their offspring’s gender, but it had far less effect on the halfway through gestation brain “genderization”.
