What is the Cass Review?
The Cass Review is a large, government-commissioned study that looked at the medical and psychological care being given to gender-questioning children and teenagers in the United Kingdom. Detransitioners who have followed the work describe it as a “systematic review of evidence on care trans youth receive,” carried out because the number of young people identifying as trans has “quickly increased over the last decade” – dieKreatur source [citation:97166804-4247-45b3-973c-86c7ae583ffb].
Key findings highlighted by people who have read the report
- Very weak evidence for puberty-blocking drugs. The review concluded that “evidence for puberty blockers protocols are almost nonexistent.”
- Children are being rushed. The report notes that “children are kinda rushed to transition in UK,” with some youngsters receiving hormones after only two or three short appointments.
- The “vast majority stay trans” claim is not supported. The review states that “in state of current evidence it’s not true that vast majority of trans youth will remain trans.”
- Detransition is more common than previously admitted. Detransitioners point out that the Cass Review, together with two newer Canadian reviews, “practically confirm … the 1 % [detransition rate] is wrong and this phenomenon is poorly researched” – DetransIS source [citation:1c8c1d05-a647-4bcf-8d2b-984faf2d8663].
Response to activist criticism
After the report was released, trans-rights advocates raised many objections. The Cass team later published a detailed update that, according to readers, “addresses the issues raised by trans activists” and shows that “all of the arguments leveraged against the report turned out to be … false or entirely made up” – cagedbunny83 source [citation:ec3a51e2-5cfe-428d-ba06-b0b56321baa3].
In short, the Cass Review is an evidence-based examination that questions the safety, effectiveness and speed of current medical transition pathways for young people, and it has become a key reference for those seeking non-medical routes to well-being and self-understanding.
