In sum, gender identity, whether consistent or inconsistent with other sex characteristics, may be understood to be "much less a matter of choice and much more a matter of biology" (Coolidge et al., 2000).
The scientific evidence supports the paradigm that transsexualism is strongly associated with the neurodevelopment of the brain (Zhou et al., 1995; Kruijver et al., 2000).
It is clear that the condition cannot necessarily be overcome by "consistent psychological socialisation as male or female (tried and tested, behavioral therapy does not help)
from very early childhood" ... It is understood that during the fetal period the brain is potentially subject to the organising properties of sex hormones (Kruijver et al., 2000; 2001; 2002; 2003).
In the case of transsexualism, these effects appear to be atypical, resulting in sex-reversal in the structure of the BSTc, and possibly other, as yet unidentified, loci (Kruijver, 2004).
The etiological pathways leading to this inconsistent development almost certainly vary from individual to individual, so no single route is likely to be identified.
Different genetic, hormonal and environmental factors, acting separately or in combination with each other, are likely to be involved in influencing the development of the psychological identification as male or female.
Psychosocial factors and cultural mores are likely to impact on outcomes (Connolly, 2003)
intersex conditions, maternal stress levels, deficient enzymes and whether the mother was exposed during the pregnancy to endocrine disrupting chemicals are also things to take account for.
http://www.who.int/genomics/gender/en/index1.html In most gender dysphoric children, gender dysphoria will cease when they reach puberty, whereas adolescents with a GID will likely pursue their wish for sex reassignment into adulthood (Cohen-Kettenis and Pfäfflin 2003; Wallien and Cohen-Kettenis 2008; Zucker and Bradley 1995). Likewise, in children under age 12 with co-occurring ASD the gender dysphoria alleviated and in adolescents between age 12 and 18 their GID persisted.

In any case, I do see there's no point in referencing biological markers insofar as proving and therefore validating ->-bleeped-<- somehow.
But only discerning psychological causes has been overruled.
