Science Explainer: Is being transgender a choice? The evidence says no. Identical twins show ~39% concordance for trans identity; fraternal twins near zero. Prenatal-hormone & brain studies point the same way. The Endocrine Society calls it "a durable biological element underlying gender identity" — exactly why the APA & WPATH reject conversion therapy: you can't change what wasn't chosen. Not new. Not an illness. Not a choice. https://codeberg.org/ReclaimAllies/reclaim-allies/src/branch/main/science/2026-07-17-explainer-is-being-transgender-a-choice.md #Trans #Transgender #FactCheck #Science
