"Conflicting results contributed to the difficulty of identifying specific brain features which consistently differ between cisgender and transgender or between heterosexual and homosexual groups"

"before hormonal treatment, in transgenders the most important brain parameters..tend to be congruent with the gender assigned at birth—after hormone treatment they partly adjust to the characteristics of the desired gender"
"Complex human behaviors..cannot be entirely explained by phenomena occurring only in a single brain region. Therefore, the idea that brain sexual differences cause behavioral sexual differences, rather than being an assumption, still constitutes a hypothesis to verify."
"the structural, functional, and metabolic variations found in homosexual transgenders..may be related to their sexual orientation rather than to their gender identity. A recent study identified brain regions where both sexual orientation and gender identity seemingly interact"
"future studies should: (4) report sexual orientation of individuals that comprise the sample size in studies on gender identity;
(6) differentiate with respect to early- or late-onset transgenderism to reach a better understanding of the biological features underlying them."
(6) differentiate with respect to early- or late-onset transgenderism to reach a better understanding of the biological features underlying them."
"Future reviews in the topic should extend the inclusion criteria to distinguish between pre- vs. post-pubertal and pre- vs. post-hormonal treatment" Amen to that.
