@benkesslen (@techreview) is the latest journalist to jump on the bandwagon of misinformation surrounding pediatric gender medicine.

🧵

technologyreview.com/2022/08/18/105…
Considering how easy it is to fact-check these articles into the ground, you have to wonder how much editorial oversight is being exercised here.

Kesslen claims that ROGD is a fiction and that @LisaLittman1 2018 paper in PLOS One is responsible for a spread of misinformation.
First, Littman has always recognized the limitations of her study. Her goal was to describe what appeared at the time to be a newly emerging clinical cohort of transition-seekers. She called for more research to corroborate the ROGD hypothesis.
PLOS One's decision to temporarily take down Littman's paper was driven by pressure from activists. The real story here is not that the paper was taken down, but that it was republished after a second round of peer review (and not, as Kesslen writes, with a "large correction")!
Since 2018, three types of evidence have made Littman's findings more credible. (1) Data from gender clinics around the world, most notably the U.K., showed that the underlying demographic characteristics of ROGD were very much behind the huge surge in referrals. (Cass Review)
(2) Clinicians working in this specific field noted in peer-reviewed articles that Littman's descriptions align with what they were seeing in their day-to-day work and called for more research on ROGD.

Even the Dutch experts who developed pediatric transition have said the same.

publications.aap.org/pediatrics/art…

Thomas Steensma has said that other countries are "blindly adopting" the Dutch approach (2021)--"blindly," b/c it was not developed for the predominant presentation (ROGD).
(3) A study by Littman in 2021 on detransitioners revealed that some had come to their trans identity through social influences.

How to account for the upsurge in the number of teens showing up for transition, the flip in sex and age ratios since the Dutch studies of the 1990's, increasing regret/detransition, and the high degree of psych co-morbidities? Social contagion is the most plausible hypothesis.
There's a difference between saying "we've proven ROGD" and saying "ROGD is very likely, and given the risks of medicalizing we should refrain from doing so pending further research." Few are saying the former, and so Kesslen is essentially setting up a straw man.
Second, Kesslen's own citations are deeply misleading.

Kesslen, e.g., cites this collection of studies. But some of the studies explicitly warned that no conclusions about causal links could be drawn from their findings.

whatweknow.inequality.cornell.edu/topics/lgbt-eq…
More importantly, I looked at 15 at random, and not one was actually about minors. Further, virtually all were done before 2016, when ROGD emerged as a clinical category of concern.

Seems like a problem for an article on CONTEMPORARY PEDIATRIC gender medicine, no?
Another example: Kesslen cites a study by Kristina Olson from this year showing that 94% children who were "affirmed" in the gender identity persisted in that identity five years later.
But as I've explained, the best and maybe only way to square Olson's findings with all past research on persistence/desistence rates in children is by assuming that social transition is iatrogenic. Olson's paper is evidence AGAINST "affirming" care.

city-journal.org/new-study-cast…
In short, Kesslen cherry-picks studies that (he thinks) help his case and ignores those that weaken it.

Third, Kesslen never once mentions developments in Sweden, Finland, and the U.K., where health authorities have drastically scaled down "affirming" care.
Health authorities in these countries have observed sharp changes in the composition of patient cohorts and expressed worries about ROGD. By now, there is simply no excuse for any journalist writing on this issue to ignore these developments.
Finally, Kesslen resorts to lazy appeals to authority, telling us about how most major US medical organizations support affirming care. He ignores the mounting evidence that these groups have been captured by activists and led astray.

WPATH's entire model of care is premised on a single body of low-n, sample-biased Dutch studies that are of very low quality and have never been replicated.

The Endocrine Society's 2017 guidelines were rated, by itself, as resting on "low" or "very low" quality of evidence.
A subsequent peer review of these guidelines gave WPATH a score of 0/6 and ES 1/6.

🚨While attention has been focused on medical groups backing off from gender surgeries in minors and a $2M detransitioner lawsuit, an important exchange has taken place in Stat News Opinion First between authors and critics of the HHS report on pediatric gender dysphoria.

👇
Last week, a group of self-described “pediatric bioethicists” and advocates for pediatric medical transition (PMT), including Yale Medicine’s Meredithe McNamara, criticized the HHS report, writing that “analysis of its poor ethical reasoning remains urgently needed.” Image
Today, a group of HHS report authors responded, explaining why the report’s reasoning is consistent with widely accepted principles of medical ethics and pointing to serious flaws in the McNamara group’s article. Image

BREAKING: American Society of Plastic Surgeons issues new position statement opposing "gender-affirming" surgeries in adolescents under the age of 19.

ASPS also acknowledges risks of endocrine interventions, poor guidelines, and inappropriate use of "autonomy" principle. Image

Thousands of U.S. parents have consented to having surgeons remove their daughters' breasts after being assured that their daughters were at serious risk of suicide otherwise.

Now, the incoming president of WPATH says mastectomy "in and of itself" doesn't prevent suicide.
This is the result of our data analysis of U.S. insurance claims. A bare minimum of 5,200 teen girls had their breasts amputated as part of a "gender-affirming" procedure between 2017 and 2023.

The true number is likely quite a bit higher. Image

1/ As @abigailandwords correctly notes in @NRO, the @APApsychiatric agreed to participate in the peer-review process and condemned the report for overlooking 16 studies, but the APA itself overlooked the HHS report's evidence review, which included 12 of those studies. In fact, several of them (e.g., Tordoff, Chen, de Vries) were discussed in detail in the main report. Of the remaining 4 studies, 3 were on adults rather than youth, and 1 was published after the HHS Review came out (though the final version does account for it).

2/ Here is a summary of the allegedly overlooked studies cited by @APApsychiatric and where they appear in the HHS Review. It can easily be found in the Supplement, which was published on Wednesday. Image

3/ The APA had no response to our analysis of studies like Chen (2023) and Tordoff (2022), or to the umbrella review, which is mentioned throughout the report.

The APA did not engage with, and possibly did not even see, the most critical part of the HHS Review.

🚨With a puberty blocker trial looming in the UK, here is why the HHS Review concludes: "administering [pediatric medical transition] to adolescents, even in a research context, is in tension with well-established ethical norms for human subjects research." 1/5

Big news 🚨

District court vacates Biden-era rule declaring that “sex” in Section 1557 of the ACA includes “gender identity.”

This rule and its antecedents in the Obama years mandated that healthcare providers offer “gender-affirming care.” 1/ Image
2/ The court disagreed with the Biden HHS that the Supreme Court’s reasoning in Bostock v. Clayton Country (2020) requires interpreting Title IX (imported into 1557) to mean that sex = gender identity.

Even if that were true, the court adds, Bostock doesn’t compel gender Rx.
3/ The court finds that the Biden HHS exceeded its authority when interpreting Section 1557 as it did.

Interpreting sex as “gender identity” is a legislative act, and thus something only Congress may do.
