In 90% of the cases, MtF transgenderism is just a paraphilia. They are crossdressers, transvestites, and autogynephiles. In many cases, the transgenderism simply goes away. If it vanishes regularly like that, then there cannot be anything wrong with their brains and of course it’s just a mental disorder. In the several areas in which male and female brains differ, autogynephilic transgender people’s brains look exactly like male brains. However, in four or five areas that are the same in both males and females, autogynephiles’ brains are different from both sexes. These brain changes may be the source of the mental disorder.
There is an incel on an incel board who identified as transgender in adolescence and went on hormones. He lost 3-4 inches in height and there is something wrong with his face as a result of the hormones. He now describes his transgenderism as a delusion, which it was of course.
Of course it’s a delusion if a man insists he is really a woman. How could it not be a delusion?
10% of transgender people are the real transsexuals. These are all gay men. These are biological transsexuals with a very early onset, sometimes as early as age two. Their brains are different. There are several parts of the brain that are quite different in men and women. In these brain areas early onset transsexuals have brains that are in between male brains and female brains. That is, their brains are female-shifted.
Now that does not mean that they have women’s brains in men’s bodies, but their brains are somewhat feminized. And yes, it does seem to be related to hormonal aberrations in the womb. This transgenderism is more valid because it involves actual changes in brain structures. Nevertheless, if these men insist that they are really women, that is a delusion in my opinion because it’s just not true.
I know little about FtM transsexuals except that 99% of them are lesbians. I am not aware of any good work on FtM transgender people’s brains.
There is a new phenomenon called Rapid Onset Gender Dysphoria which is hitting teenage girls in an epidemic form. It spreads like anorexia as a social contagion in emotionally susceptible teenage girls. This is simply a mental illness like Anorexia and in fact, it may be closely related to Anorexia because it resembles Anorexia in many ways and it also involves distorted body image.
