Transgender women tend to have brain structures that resemble cisgender women, rather than cisgender men. Two sexually dimorphic (differing between men and women) areas of the brain are often compared between men and women. The bed nucleus of the stria terminalus (BSTc) and sexually dimorphic nucleus of transgender women are more similar to those of cisgender woman than to those of cisgender men, suggesting that the general brain structure of these women is in keeping with their gender identi...
In 1995 and 2000, two independent teams of researchers decided to examine a region of the brain called the bed nucleus of the stria terminalis (BSTc) in trans- and cisgender men and women (Figure 2). The BSTc functions in anxiety, but is, on average, twice as large and twice as densely populated with cells in men compared to women. This sexual dimorphism is pretty robust, and though scientists don’t know why it exists, it appears to be a good marker of a “male” vs. “female” brain.

Thus, these two studies sought to examine the brains of transgender individuals to figure out if their brains better resembled their assigned or chosen sex.

Interestingly, both teams discovered that male-to-female transgender women had a BSTc more closely resembling that of cisgender women than men in both size and cell density, and that female-to-male transgender men had BSTcs resembling cisgender men.
These findings have since been confirmed and corroborated in other studies and other regions of the brain, including a region of the brain called the sexually dimorphic nucleus (Figure 2) that is believed to affect sexual behavior in animals.
Several studies confirmed previous findings, showing once more that transgender people appear to be born with brains more similar to gender with which they identify, rather than the one to which they were assigned.

RESULTS:
In controls, males have significantly higher FA values than females in the medial and posterior parts of the right superior longitudinal fasciculus (SLF), the forceps minor, and the corticospinal tract. Compared to control females, FtM showed higher FA values in posterior part of the right SLF, the forceps minor and corticospinal tract. Compared to control males, FtM showed only lower FA values in the corticospinal

CONCLUSIONS:
Our results show that the white matter microstructure pattern in untreated FtM transsexuals is closer to the pattern of subjects who share their gender identity (males) than those who share their biological sex (females). Our results provide evidence for an inherent difference in the brain structure of FtM transsexuals.

Brain development is heavily influenced by the prenatal environment – what hormones the fetus is exposed to in its mother’s uterus. Some scientists believe that female-to-male transgender men, for instance, may have been exposed to inadequate levels of estrogen during development (Figure 3). This phenomenon could have two causes: 1) not enough estrogen in the fetus’s immediate environment, or 2) enough estrogen in the environment, but poor sensitivity in the fetus. Think of it like a cell phone tower controlling remote calls – the tower may not be producing enough signal (scenario 1), or the receiving phone may be unable to process the message (scenario 2). In either case, the call doesn’t make it through.

Figure 3: Possible scenarios underlying insufficient feminization. During normal feminization, sufficient estrogen is present in the fetal environment. The estrogen is recognized by fetal cells and triggers the development of a female fetus. In Scenario 1, very little estrogen is present in the fetal environment. Even though the fetal cells are capable of sensing estrogen, very little enters the fetal environment and the fetus is insufficiently feminized. In Scenario 2, there is enough estrogen in the fetal environment, but fetal cells are effectively “deaf” to the estrogen and the fetus is insufficiently feminized.

The amount of estrogen in the fetal environment is a little tough to measure – but there appears to be some evidence for transgender individuals having poor hormonal sensitivity in the womb. A team of researchers found that the receptor for estrogen (that is, the cell phone receiving the signal) seems to be a little worse at receiving signal in female-to-male transgender men – think a 2001 flip phone trying to process photos from Instagram. Thus, the signal doesn’t come through as clearly, and the externally “female” fetus ends up more masculinized.

The psychological studies that have attempted to unravel the causes of transsexuality, on the other hand, have largely failed to gain traction in modern times. For many years, psychologists characterized transgender identity as a psychological disorder. Some, for instance, believed it was a coping mechanism to “rectify” latent feelings of homosexuality, or the result of environmental trauma or “poor” parenting. No studies have been able to demonstrate this, however, and these “findings” are considered outdated and have been highly criticized for their discriminatory implications. Other psychologists have attempted to differentiate groups of transsexuals based on factors such as IQ and ethnicity; similarly, these theories have been overwhelmingly rejected due to poor study design and issues with ethics.

And so, while the list of causes for transgender identity continues to grow, it has become quite clear that it is not a conscious choice – similar to what has been described for the “reasons” behind sexual orientation. Still, at least 63% of transgender individuals experience debilitating acts of discrimination on a regular basis, including incarceration, homelessness, and physical assault. When about 1.7% of the population is in some way affected by cases of ambiguous genitalia at birth, these findings seem staggering.

So, where do we stand on transgender issues? Science tells us that gender is certainly not binary; it may not even be a linear spectrum. Like many other facets of identity, it can operate on a broad range of levels and operate outside of many definitions. And it also appears that gender may not be as static as we assume. At the forefront of this, transgender identity is complex – it’s unlikely we’ll ever be able to attribute it to one neat, contained set of causes, and there is still much to be learned. But we know now that several of those causes are biological. These individuals are not suffering a mental illness, or capriciously “choosing” a different identity. The transgender identity is multi-dimensional – but it deserves no less recognition or respect than any other facet of humankind.

Matt get yourself a expensive hooker with big tattas, maybe some blowski, maybe two hooks.

Then report back on your findings please?

Not necessarily as we aren't really sure what BSTcs do and cannot be easily attributed to sexual orientation, hormones, or other seemingly plausible incidental causes. Finding differences in the brain is not always evidence of cause, it is just as scientifically plausible that social causes are responsible for the brain differences, unlike a computer our brain is not static. Then we have the research itself and the extremely low sample size, not necessarily a problem but it raises the possibility of the results being a fluke from a statistical standpoint and in a study such as this the sample size needs to be huge to get an accurate overall reading.
Not claiming the study is specifically bad or inherently flawed just indicating that without a much larger sample size and actually peer reviewed studies as well as a determination of the actual causes of neuro-chemical processes and distinct causative relationships we are still only guessing. We have much more work to do in order to make definitive (empirical) claims.

Our results provide evidence for an inherent difference in the brain structure of FtM transsexuals.

It appears to me that the science supporting transgendermism as natural is quite strong.
Can science also show that the tendency to molest children is also natural, so we can be more accepting of theses type humans?


It shouldn't be too hard too slide bestiality through as well then?
I do think such people definitely have something wrong with their brains making them as as fucked up as a cow hit by a train. This doesn't condone them abusing children or animals, but understanding is the first step to "fixing".
 
Transgender women tend to have brain structures that resemble cisgender women, rather than cisgender men. Two sexually dimorphic (differing between men and women) areas of the brain are often compared between men and women. The bed nucleus of the stria terminalus (BSTc) and sexually dimorphic nucleus of transgender women are more similar to those of cisgender woman than to those of cisgender men, suggesting that the general brain structure of these women is in keeping with their gender identi...
In 1995 and 2000, two independent teams of researchers decided to examine a region of the brain called the bed nucleus of the stria terminalis (BSTc) in trans- and cisgender men and women (Figure 2). The BSTc functions in anxiety, but is, on average, twice as large and twice as densely populated with cells in men compared to women. This sexual dimorphism is pretty robust, and though scientists don’t know why it exists, it appears to be a good marker of a “male” vs. “female” brain.

Thus, these two studies sought to examine the brains of transgender individuals to figure out if their brains better resembled their assigned or chosen sex.

Interestingly, both teams discovered that male-to-female transgender women had a BSTc more closely resembling that of cisgender women than men in both size and cell density, and that female-to-male transgender men had BSTcs resembling cisgender men.
These findings have since been confirmed and corroborated in other studies and other regions of the brain, including a region of the brain called the sexually dimorphic nucleus (Figure 2) that is believed to affect sexual behavior in animals.
Several studies confirmed previous findings, showing once more that transgender people appear to be born with brains more similar to gender with which they identify, rather than the one to which they were assigned.

RESULTS:
In controls, males have significantly higher FA values than females in the medial and posterior parts of the right superior longitudinal fasciculus (SLF), the forceps minor, and the corticospinal tract. Compared to control females, FtM showed higher FA values in posterior part of the right SLF, the forceps minor and corticospinal tract. Compared to control males, FtM showed only lower FA values in the corticospinal

They're not humans, more like animals that need put down
Agree...but that is where liberalism will take us.

The left can't even fathom the damage that is done to a child who has been sexually abused. Trust goes out the window and recovery is a painful process that may last a lifetime.
