Sallie Baxendale is a respected neuropsychologist. She has published books and

studies over many years about brain function, brain structure and brain

development. In this video clip, she reports on her work which has analyzed the

research studies which have looked at the impact on brain development of

puberty blockers. Sallie highlights:

the complexities involved in brain research

there is cause to have major concerns about the use of puberty blockers given

the potential for harms

Baxendale states that the fact that puberty blockers have been used as a

treatment for gender questioning children for a number of years without having

good research about the outcomes, constitutes a medical scandal.
