A new article in @IACAPAP’s bulletin offers a summary of SEGM’s Berlin Conference 2025: “The conference provided a rare forum for researchers and clinicians to grapple with the unanswered questions that sit at the heart of pediatric gender medicine.” Link⬇️/1

Activists’ suppression of research on ‘gender-affirming’ care needs to stop

The Government of Queensland has decided to prolong restrictions on the use of PB and CSH after considering the conclusions of an Independent Review led by Professor Ruth Vine. The restrictions will remain in place until the outcomes of the PATHWAYS trial are known in 2031. /1

🔥 Exceptionally clear and compelling discussion, led by @DrJBhattacharya, with the authors of the HHS review of medical treatment for pediatric gender dysphoria. TLDR: the evidence base for benefits of drugs & surgery is weak, while harms (e.g., infertility) are clear. Methods

In this thoughtful article in @kevinmd, Dr. @will_malone (cofounder of SEGM) examines how ideology in gender medicine has led to efforts to shut down evidence, debate, and even medical education. He makes a strong case for protecting scientific inquiry and clinical humility. /1

"We wrote the HHS review on treatment for minors with gender dysphoria. We hope our critics actually read our report."

This @Newsweek editorial, written by two Biden admin ex-HHS officials, is an example of what philosopher Dan Williams calls "highbrow misinformation." It relies on a litany of misleading or incorrect stats to back up its claim that the recent HHS report on pediatric gender

Dr. Mikael Landén from Sweden's Karolinska explains why short-term research into hormone treatments of gender-dysphoric youth is unreliable. Instead, new research should focus on "natural history": we must find out if gender dysphoria in this new group remits spontaneously. 1/2

NEW: I’ve taken a deep dive into the new puberty blockers trial, exploring how we got here, what it will and won’t answers, with a sprinkling of new revelations too. With contributions from Hilary Cass, trial team members (past & present) and MPs https://t.co/0uMRuSyLyS

Gender clinics often use the "suicide narrative" to pressure parents into gender transition for their kids. A new paper on youth treated at Mercy Children’s gender clinic claims hormones reduced suicide. Our analysis reveals serious methodological flaws. https://t.co/7xHSWAFFPU

🚨SEGM’s Digest highlights new publications poised to influence the debate in youth gender medicine. We begin with a recent study which claims that hormones reduce youth suicidality. Our conclusion: like other studies making similar claims, this study's finding is unreliable./1

A must-listen/read interview between @DouthatNYT and Chase Strangio in the NYT today. While the tone toward critics of youth gender transition is more collegial, Strangio still misstates the evidence, claiming hormones are proven to significantly reduce distress & suicidality. /1

Do puberty blockers work like a harmless “pause button” when it comes to the developing brain? In SEGM’s medical education course, University College London neuropsychologist Dr. Sallie Baxendale evaluates the evidence. 1/2

When I first found out who was on the Trump administration's HHS review on youth gender medicine I was gobsmacked by the sanity and competence of the group. Really dodged a bullet, not that it will matter -- the usual suspects will continue lying about the evidence base.

🚨🚨 Breaking News: co-executive Director @Jamiewhistle just spoke before the WSU Board of Regents about the ongoing suspension of @SEGM CME Courses. WSU’s own review team spent nine months vetting and approving these trainings.

🧵As the number of detransitioners has visibly grown, so has the need to develop clinical services to support them. Last week, NHS England announced that it is seeking input from healthcare professionals (not limited to UK) with experience in detransition care & research gaps. /1

🚨A new study about sex concludes that size matters. The size of gametes, that is. “Male” organisms' biological function is to produce small gametes (sperm), and “female” organisms's function is to produce large gametes (ova). There are only 2 sexes, concludes @SwipeWright./1

As the article below details, activist demands have led to a suspension of 7 continuing medical education courses in youth gender medicine. Based on SEGM's 2023 conference lectures, the courses feature European clinicians discussing Europe's shift away from youth transitions./1

🚨BREAKING: My Commentary in Archives of Sexual Behavior—“Why There Are Exactly Two Sexes”—has been published! In it, I explain why biological sex is binary in all anisogamous species, defined strictly by the type of gamete (sperm or ova) an organism’s reproductive system has
