This article presents framework guidelines for the care of adolescent transgender (T) and non-binary (NB) individuals experiencing gender dysphoria (GD) and/or gender incongruence (GI). Developed by a multidisciplinary expert panel, these guidelines aim to address the complex medical, psychological, and social needs of this diverse population. The document emphasises the importance of individualised, affirmative care that respects the autonomy, identity, and rights of adolescents. It outlines best practices for psychiatric, psychological, and sexological assessment
criteria and protocols for gender-affirming hormonal interventions (GAHI) and puberty suppression
and ethical considerations for medical decision-making. The guidelines advocate for comprehensive support systems, including family involvement and multidisciplinary team collaboration, while addressing co-occurring mental health conditions and neurodiversity. The article also highlights global perspectives on gender-affirming care, comparing practices and policies across countries to provide a contextualised approach that aligns with international standards while addressing local legal and healthcare frameworks. The proposed care model is designed to enhance the mental and physical well-being of adolescents, reduce stigma, and improve their overall quality of life. This work serves as a vital resource for healthcare professionals, policymakers, and advocates seeking to advance equitable, effective, and compassionate care for gender-diverse youths.
