The following list of links is to demonstrate that there is a very large body of evidence pointing to brain differences beginning in utero as the fundamental cause of most instances of transexuality. Part of the resistance to the brain-sex theory comes directly from Dr. Anne Lawrence who critiqued two early studies in this area (clear back in 2002) but who has a personal vested interest in arguing a different basis as she has based her entire career on that different basis. This list is not even close to comprehensive.

Think Like A Man: Testosterone Treatment Allows Transgender Men To Think And Talk Like A Man
(Note that the above article title is problematic in that it implies trans men are not men so only talk “like” men. But the hormonal research is interesting.)
Homosexuality may be caused by chemical modifications to DNA This is important because it ties back again to hormonal in utero differences driving white matter brain structure differences.
The brains of men and women aren’t really that different, study finds – This study actually reinforces the neurobiological understanding of being transgender. I explain this here, in New Brain Study Reinforces Neurobiological Explanation of Being Transgender
Removing transgender identity from the classification of mental disorders: a Mexican field study for ICD-11 (Note that this study shows that transgender mental health issues are not because we are transgender, but because people are cruel and inhumane to transgender people generally, resulting in widespread social rejection.)
Sexual differentiation of the human brain in relation to gender identity and sexual orientation. “Although the crucial question, namely how such complex functions as sexual orientation and identity are processed in the brain remains unanswered, emerging data point at a key role of specific neuronal circuits involving the hypothalamus.”
Is There Something Unique about the Transgender Brain? Imaging studies and other research suggest that there is a biological basis for transgender identity
Miscellaneous and Useful Documents For Trans Individuals
For convenience, the DSM-5 clearly states, gender dysphoria is not a mental disorder.
The following link helps expose why the autogynephelia diagnosis is pure garbage, which means Bailey, Blanchard, etc., are basically full of nonsense. (Because women get aroused thinking of themselves as women too.)
