The Cass Review: Towards an Evidence-Based Approach to Transgender Care for Youth

The Cass Review has highlighted significant shortcomings in the evidence for gender affirming treatments for transgender youth, calling for a more holistic approach. The US continues to rely on the gender affirming model despite criticisms of the supporting evidence, while the UK has seen changes following the release of the review. The review also raises concerns about the role of medical associations in guiding care without strong evidence.

Gender identity is a complex and multifaceted aspect of human existence. For some individuals, their gender identity may not align with the sex assigned to them at birth. This can lead to a range of challenges and difficulties, particularly for young people navigating their identity during puberty. In recent years, the treatment of transgender youth has become a highly debated topic, with differing opinions on the most appropriate approach. The Cass Review, led by Professor Christopher Cass, has shed light on the current state of evidence supporting the use of puberty blockers and hormones for transgender youth. In this article, we will explore the key findings of the Cass Review and its implications for the care of transgender youth.

The review, conducted over a period of four years, concluded that the evidence on the use of puberty blockers and hormones in transgender youth is lacking, and called for a more holistic approach to care. This is in stark contrast to the current medical guidelines, which heavily endorse the gender affirming model of care. The gender affirming model, which involves prescribing puberty blockers followed by hormones and surgeries, has been criticized for prioritizing medical intervention over psychological support. The Cass Review notes that this approach may explain the apparent consensus on this method of care, despite the lack of strong evidence to support it.

One of the major critiques of the gender affirming model is the lack of long-term studies on its effects on the physical and mental health of transgender youth. The Cass Review highlighted the need for more rigorous, long-term studies to truly understand the impact of these treatments. Until then, the review recommends a more cautious approach to medical interventions, particularly in light of concerns about potential irreversible effects on the body and brain development of young people.

The American Academy of Pediatrics (AAP) and Endocrine Society have stood by their guidelines despite the criticisms of the supporting evidence. This poses a problem for parents of transgender youth, who may have limited information about alternative approaches to care. This lack of information, along with a highly medicalized culture, may contribute to the dominance of the gender affirming model in the US. However, the Cass Review has had significant impact in the UK, with the prescription of puberty blockers outside of research protocols ceasing after its release.

The Cass Review also raises important questions about the role of medical associations in guiding the care of transgender youth. The review notes that the guidelines from these associations are largely based on the recommendations of the World Professional Association for Transgender Health and Endocrine Society, which themselves are lacking in scientific rigor. This has led to a situation where the recommendations of these associations are not based on strong evidence, but rather on expert opinion, potentially putting the well-being of transgender youth at risk.

In conclusion, the Cass Review highlights significant shortcomings in the evidence supporting the use of puberty blockers and hormones for transgender youth. The call for a more holistic approach to care raises important questions about the dominance of the gender affirming model and the role of medical associations in guiding care. As awareness of the review's findings grows, it is vital that we continue to critically evaluate the evidence and strive for a truly evidence-based approach to transgender care for youth.
