Later longitudinal studies and retrospective studies post genderaffirming treatment of participants diagnosed with any of the gender dysphoria diagnoses have confirmed the results, finding subjective improvement, less gender dysphoria, no or few regrets, and less psychopathological symptoms (Colizzi, et al,, 2013;Colizzi, et al, 2014;De Cuypere et al, 2006;de Vries et al, 2014;Heylens et al, 2014b;Johansson, Sundbom, Höjerback, & Bodlund, 2010;Manieri et al, 2014;Pimenoff & Pfäfflin, 2011;Ruppin & Pfafflin, 2015;Udeze, Abdelmawla, Khoosal, & Terry, 2008).
