Sergio (Paul Naschy) laat hier zien hoe humaan hij is; hij accepteert mensen die veranderd zijn van geslacht. De film geeft een globaal beeld over transseksuelen en travestieten in de jaren zeventig en de acceptatie ervan in die tijd.
Nee, helaas is El transexual nog niet beschikbaar op Netflix in Nederland.
