Research into trans medicine has been manipulated

IN APRIL HILARY CASS, a British paediatrician, published her review of gender-identity services for children and young people, commissioned by NHS England. It cast doubt on the evidence base for youth gender medicine.

WPATH said that its own guidelines were sturdier, in part because they were “based on far more systematic reviews”.
