Exerpts:

During prenatal development, the brains of most animals, including humans, develop specifically male or female characteristics. In most species, some portions of male and female brains are a different size, and often have a different number of neurons and synapses. However, scientists have known little about how this differentiation occurs. Now, a new study by researchers at the University of Maryland School of Medicine (UM SOM) has illuminated details about this process.

...............

Prof. McCarthy and Nugent also found that inhibiting Dnmts has powerful effects, even outside the usual window of development. During prenatal development there is a restricted time frame during which the brain takes on male or female characteristics. Scientists had thought that once this window closed, it could not be reopened. But the two researchers found otherwise. They succeeded in transforming the brain of a female rat after the window had closed, giving it the characteristics of a male rat brain.

Prof. McCarthy and Nugent injected Dnmt inhibitors into a specific region of the female brains, a region known as the preoptic area, or POA. In every species that's been studied, including humans, the POA plays a key role in governing male sexual behavior. The injections occurred after the first week of birth, the time when the window for brain sexual differentiation was thought to have been closed. Despite this, the preoptic area in these animals was transformed, and took on structural characteristics of a male rat. The female rats also behaved differently, displaying sexual behavior typical of male rats. In another experiment, they genetically deleted the Dnmt gene in female mice; these animals also showed male behavior patterns.

Some things to take note on.

1. There are differences between a female and male brain.
2. The "gender" of the brain can be altered by epigentics and environmental factors.
3. It can change even after taking on an identity.

Granted these are on animal models and one can not just assume is applicable on humans. With that said there is growing evidence that gender identity is not based upon one's genitals and that people's dislike for transgenders maybe based nothing more than their ignorance.

You mean to tell me that if you monkey with the chemicals in the brain, it will change how it functions?? I'm shocked...truly shocked.

Next thing you know we'll have vaginas producing sperm and penii producing eggs.

And you know they will monkey with things, because humans can't just leave well enough alone.

Well, on the serious side, DNMT appears to be also involved with disease processes like Alzheimer's and Parkinson's, so if this is where the research is leading them

Well, on the serious side, DNMT appears to be also involved with disease processes like Ataxia and Parkinson's, so if this is where the research is leading them, I'm fine with that.

Fix'd and finished.

Only if you ignore reality.
