The Cass affair

Key messages:

• The Cass Review led to the UK banning puberty blockers for transgender adolescents, after taking over from the standardised NHS review protocol.
• The Review repeatedly distorted its own scientific sources.
• The Review’s outcome was predetermined, with the same rationales for replacing the NHS protocol later recycled into rationales for restriction.
• The Review concealed its use of material from an anti-LGBT hate group.
