We performed a scoping review of current clinical guidance for the care of TGD individuals to identify what was said about autism.

Out of the identified 31 clinical guidance documents, only eleven specifically mentioned the intersection between autism and TGD. Key concepts among the available recommendations included advocating for a multidisciplinary approach; emphasising the intersectionality of autism and gender-diverse experiences during assessments; and-importantly-recognising that autism, in itself, does not serve as an exclusion criterion for receiving gender-related care.

In previous studies, IPE has prevented weight gain in middle-aged adults over 6 months, compared with the inulin control.
