Evidence-based objection to affirmative care

"Evidence-based gender-affirming care" is an empty creed. Systematic reviews have shown for years that the evidence base for puberty blockers, hormones, and surgery in minors is "remarkably weak." GRADE assessments remain stuck at "very low certainty." Yet, irreversible interventions on healthy teenage bodies are defended as if the evidence were conclusive—and anyone who contradicts this is branded as hateful.

The GRADE outcomes

The Cass Review (2024) had 237 studies systematically assessed via GRADE. The result: virtually all evidence for puberty blockers and cross-sex hormones in minors is "very low certainty". Concrete translation: we do not know if the treatment works, how large the effect is, or whether the harm outweighs the benefit. In adult oncology, no committee would accept such evidence for mastectomy of healthy breasts. In children, however, they do — because it is politically desirable.

Five national agencies, one conclusion

The Swedish SBU (2022), British NICE (2020), Finnish COHERE (2020), Norwegian UKOM (2023), and Danish Sundhedsstyrelsen (2023) independently reached the same conclusion. Five national government agencies — not lobby groups, not activists — conclude that the evidence is insufficient. The closure of Tavistock followed directly from this acknowledgment. At the same time, Dutch gender care continues as usual, citing WPATH — an organization that suppressed its own evidence review.

WPATH SOC-8 ignores its own review

The WPATH Standards of Care 8 (2022) lower age limits and relax criteria for hormone treatment of minors — directly contrary to the available evidence. Bizarrely, WPATH itself commissioned Johns Hopkins to conduct systematic reviews. When the outcomes proved unfavorable, they were suppressed. The WPATH Files (2024) and the Levine affidavit (Boe v Marshall, 2024) show the pattern: board members ignored research that contradicted their recommendations.

What requires evidence-based training — and what is missing here

True evidence-based medicine requires (1) systematic review, (2) GRADE assessment, (3) harm-benefit analysis, (4) patient preferences under genuine informed consent. Gender-affirmative care fails on all four. No long-term RCT. No consistent outcome instrument. No accurate representation of irreversibility — breasts gone, fertility gone, voice low forever. The 1% regret rate presented to patients is a methodological artifact. Transition does not cure — it confirms a misdiagnosis and closes the exit.

No marker, no test, no evidence

The diagnosis of "gender dysphoria" relies entirely on self-reporting — there is no biological marker , no brain scan , no genetic substrate . Irreversible interventions on that basis are no longer medicine; they are ideologically driven interventions on healthy bodies. In any other medical field, this would be called a scandal. Here, criticism is silenced and framed as transphobia.
