How can trans* individuals be advised and therapeutically supported in a respectful and competent manner before, during, and after their transition within the healthcare system? Due to the diversity of gender identities, expressions, and experiences of those seeking treatment, therapists encounter a wide range of needs that they can only meet impartially. This book addresses these challenges by presenting the psychosocial and medical foundations. Readers will not only gain an overview of current care standards and options but will also highlight the perspectives of various trans* lifestyles, enabling a dialogue on equal footing.
