The pushers of sex change have an agenda—to fabricate and promote false information, such as “The transgender brain is feminized” and to ignore studies that do not support their fabricated false information.
This study from The Stockholm Brain Institute, Department of Clinical Neuroscience, Karolinska Institute, Stockholm, Sweden, says that the present data do not support the notion that brains of MtF-TR are feminized. The scientists compared the sizes of various areas of brains belonging to MtF transsexuals to brains of heterosexual men and women. The findings: 1) all the males differed in the same ways from the females (no feminization of the transsexuals) and 2) the MtF transsexuals differed from both heterosexual men and women in the area of the brain that processes body perception.
Gender dysphoria is suggested to be a consequence of sex atypical cerebral differentiation. We tested this hypothesis in a magnetic resonance study of voxel-based morphometry and structural volumetry in 48 heterosexual men (HeM) and women (HeW) and 24 gynephillic male to female transsexuals (MtF-TR). Specific interest was paid to gray matter (GM) and white matter (WM) fraction, hemispheric asymmetry, and volumes of the hippocampus, thalamus, caudate, and putamen. Like HeM, MtF-TR displayed larger GM volumes than HeW in the cerebellum and lingual gyrus and smaller GM and WM volumes in the precentral gyrus. Both male groups had smaller hippocampal volumes than HeW. As in HeM, but not HeW, the right cerebral hemisphere and thalamus volume was in MtF-TR lager than the left. None of these measures differed between HeM and MtF-TR.
MtF-TR displayed also singular features and differed from both control groups by having reduced thalamus and putamen volumes and elevated GM volumes in the right insular and inferior frontal cortex and an area covering the right angular gyrus.
The present data do not support the notion that brains of MtF-TR are feminized. The observed changes in MtF-TR bring attention to the networks inferred in processing of body perception. Source: http://www.ncbi.nlm.nih.gov/pubmed/21467211
So, perhaps transgenders like to cross dress, but it does not point to a brain issue but rather a behavioral psychosis.
