Transgender and gender diverse (TGD) youth are currently being targeted by global anti-trans legislation that would prevent their access to gender-affirming care even by healthcare providers willing to deliver it and who understand the importance of this support. It has been suggested in some studies that transness in young people is a result of peer contagion. As such their free will, authenticity and autonomy could be brought into question when accessing gender-affirming care. It is important to explore the relevance of (...) these concepts concerning the provision of gender-affirming care to TGD youth by nurses and other healthcare professionals. Nurses should challenge the notion held by some that these young people are not capable of knowing themselves or the level of treatment they require. They can do this by practising gender-affirming care determined by aspirational ethical values of beneficence, non-maleficence, autonomy and justice. (shrink)
