Abstract

Gender-affirming hormone therapy (GAHT) is a medical treatment used to help transgender individuals align their physical appearance with their gender identity. GAHT in transgender women (TW) has been found to lead to a reduction in brain tissue with an expansion of the ventricles. We discuss an animal model studying the effects of GAHT that suggests dehydration of brain tissue and an alteration in the relative concentration of brain metabolites. We hypothesize that estradiol, acting on astrocytes, alters cerebral blood flow, water metabolism, and metabolite concentration and argue that these changes could explain the higher risk of stroke observed in GAHT-treated TW compared to untreated cisgender men. Future studies should clarify the mechanisms underlying the brain tissue changes induced by GAHT.

期刊介绍: Journal of Neuroendocrinology provides the principal international focus for the newest ideas in classical neuroendocrinology and its expanding interface with the regulation of behavioural, cognitive, developmental, degenerative and metabolic processes. Through the rapid publication of original manuscripts and provocative review articles, it provides essential reading for basic scientists and clinicians researching in this rapidly expanding field. In determining content, the primary considerations are excellence, relevance and novelty. While Journal of Neuroendocrinology reflects the broad scientific and clinical interests of the BSN membership, the editorial team, led by Professor Julian Mercer, ensures that the journal’s ethos, authorship, content and purpose are those expected of a leading international publication.
