Why the NHS puberty blocker trial is appalling

Stella O’Malley from Genspect telling it like it is - that a state endorsed trial of puberty blockers for gender dysphoric children should NOT go ahead.
the NHS are not walking into this nightmare blindly - there are enough experts out there telling them what will happen happen to these children if they’re given these life changing drugs.

Statement from Streeting.

I agree that there should be investigation of those who already have them but I don't have a problem in principle with a randomised trial.

Young people with gender dysphoria are able to consent to medical treatment in the UK if they meet the Granger criteria.

Ideally it might be say therapy along versus therapy with puberty blockers randomised. Edit - the therapy in both cases starting before puberty blockers. Screened out certain other mental illnesses as is standard in trials.

That way we can see if puberty blockers do or do not help those with gender dysphoria, a real condition that causes considerable suffering.

Opposing it sounds like the kind of "wanting to erase trans" gender criticals are accused of.

What is the condition though? If it is psychological why is it begin treated physically? 'Puberty blockers' are widely used to treat other conditions, so we know about many of the side effects, but here they are being used for a different purpose, to potentially preventing a child reaching sexual maturity.

It's more akin to allowing people to have limbs amputated to relieve their body dysphoria.

This includes the PATHWAYS trial, a carefully designed, randomised controlled clinical trial of puberty suppressing hormones for gender incongruence. This trial will involve young people being treated in NHS Children and Young People’s Gender Services with a formal diagnosis of gender incongruence.

So Wes, if you believe that the trial has been carefully designed, please do explain the meaning of 'gender incongruence' and why this is a condition that requires treatment.

I mean, in theory sure ... but

The children will not be consenting here, parents/guardians will on their behalf.

I do not understand how parents/guardians can ethically consent to a process that may leave these children sterile/never reaching sexual maturity/inhibiting physical and intellectual development. Do you?

I assume the desired outcome is to get the “evidence” they need to continue to prescribe puberty blockers to anyone who asks for them. They already know the results will be positive. Imagine the pressure on those poor children to report an improved mental state. The experiment is short enough that none of the longterm consequences will be seen. Children will still be in the grasp of the trans cult by the end of the process. It’s so massively flawed. Even Wes’ X post gives the game away. He has no doubt that the result will give them the “evidence” they need. The whole thing is fake.

“We're now setting up clinical trials to build the evidence base we need to support vulnerable children properly.”

The research we have doesn't at all suggest that outcomes will be positive but by using the usual short-term assessment period it may be possible to produce a larger than usual study that nonetheless drapes itself in rainbows & glitter.

The study should never have passed the ethics committee. Lifetime follow-up is possible for every participant who remains in the UK & that follow-up & its public reporting should have been the absolute minimum requirement for this hideous project.

IMO we should have stopped the prescribing of both GnRHas & cross-sex hormones to under 18s & instead returned to the sheep model.

So 2000 people have been through puberty blocker trials under the work of the Tavistock et al and not one bit of research has been published using their data?

Don't forget the Tavi's abandoned trial that attempted & failed to reproduce the positive results in the original Dutch study. They abandoned it because it wasn't giving them the pretty metrics they assumed they should get.

No bloody wonder there's a Crisis of Replicability. 🙄

MalagaNights · 24/11/2025 15:10

What is the criteria for judging if it 'helps'?

Is it A) they feel happier and want to continue on to cross sex hormones?

Or is it they B) feel happy now to accept their body and go through natural puberty?

If there was any evidence it might increase the chances of B) that might make this acceptable.

But this experiment has already been done and 98% had outcome A). Which we know leads to sterility and loss of sexual function.

How is that helping anyone?

I just cannot see anyone being clear that the best outcome for 'gender incongruence' is accepting your healthy body and not extreme body modification.

These are being treated as if they are both equally successful as long as you are 'happy'.

@MalagaNights I am no expert but I guess the same way mental health treatment is measured.

Of course it would be great if those with gender dysphoria could just accept their sex. It's not that simple.

So far no psychological treatment has been shown to help gender dysphoria.

Except perhaps where there are concurrent conditions so that's why it's so important to treat these which the Tavistock clinic wasn't.

So that's why I suggested an initial period of psychotherapy and psychiatric assessment and exclude certain concurrent conditions.

Manteiga · 24/11/2025 15:31

JamieCannister · 24/11/2025 13:20

I agree completely.

It was more that I was trying (quite possibly badly) to talk about consent, and if society is massively transphobic according to the sorts of people who are pushing for this PB trial to go ahead, then surely the people who are pushing for this PB trial to go ahead can only get informed consent after telling the potential child participants of the constant transphobia that they will face.

If the TRAs pushing this trial are not doing this, then it is yet another example of their hypocrisy and dishonesty.

Either society is not transphobic, and they need to stop with the accusations that we are, or society is transphobic and they need to ensure that PB trial participants who are at risk of a life of being on the receiving end of transphobic bullying know what they are letting themselves into.

I don't think this is quite the same argument as the argument about the law. Clearly for informed consent all "trans kids" would need to be made to fully understand that most people believe that the sex based rights of women and LGB trump the cross-sex privileges of trans people, and that the only way that they can "live as the opposite sex" is to play at dress up, and not to use opposite sex facilities.

I'm trying to think of another example. Imagine you have severely damaged legs, which just about work but leave you moving around slowly and in significant pain. If you live in a very flat, modern country with amazing laws that ensure wheelchair bound people can get wherever they want, whenever they want, then amputation is probably your best option. If you live in a mountainous country with a history of associating physical disabilities with mental disabilities, and total disrespect for both, then maybe you're better off struggling up steps in pain. It would be totally wrong to have a conversation about consent for amputations that did not bring up the way the country is not set up (physically or in terms of attitudes) for those in wheelchairs.

Good point. But what is the trans equivalent of the "flat, modern country" for which medical transition would be a no-brainer? In Transutopia you need only declare your pronouns for everyone else to instantly start seeing you as the sex you want to be - why put yourself through an unnecessary pharmaceutical and surgical ordeal? More realistically, you'll be able to fool some, while the rest will play-act at being fooled from pity or fear. That doesn't seem a healthy situation - or a happy one - regardless of the proportion of people that are genuinely fooled.

TheKeatingFive · 24/11/2025 15:12

Not only that, but they claim they do t have any data - it wasn't collected.

But we do know 98% went onto cross sex hormones.

So the 'gender incongruence' persisted. It didn't 'help'.

And we know the serious impacts on health from cross sex hormones.

So what evidence are they expecting to see that could be judged as 'helping' or 'success' on how to treat these kids?

The only possible evidence is more evidence of what not to do, which is insane, evil and should be criminal.

MistyGreenAndBlue · 24/11/2025 15:33

RoyalCorgi · 23/11/2025 19:44

I'm another one struggling to see what a successful outcome might look like. Presumably it would mean no physical ill-health effects (loss of bone strength etc), and that the child's mental wellbeing remained the same or improved. As the children are also going to be receiving therapy, that's an obvious cofounder, so I don't see how that is going to work.

I agree with a PP that it's plausible that Wes sees this as a way of confirming once and for all that puberty blockers are dangerous and that the sacrifice of 226 children is worth it - perhaps because a two-year trial will do a limited amount of harm.

I thought the standard was: "First do NO harm". Was I wrong?

ArabellaSaurus · 24/11/2025 15:37

A couple of excerpts from HoC debate last year on the subject:

https://hansard.parliament.uk/commons/2024-04-15/debates/AFE3A39A-3333-4790-AE30-776A474188C4/CassReview

'As recently as 2009, the NHS’s sole gender identity development service at the Tavistock and Portman NHS Foundation Trust received fewer than 60 referrals for children and young people, and just 15 for adolescent girls. Since then, demand has surged. By 2016, over 1,700 children and young people a year were referred—a 34-fold increase. More than half were teenage girls. In 2022, more than 5,000 children and young people were referred to gender identity clinics, and almost three quarters were female.

Dr Cass also found that there was a lack of robust data on what happened to the 9,000 children who were treated by gender identity services between 2009 and 2020. Many went on to continue their treatment at adult clinics, and the University of York had been due to research the long-term consequences of treatment they received as children, so that we can properly support them through their journey into adulthood. It was expected to provide important insights into the clinic’s work, including how many patients de-transitioned and how many were also diagnosed with a mental health condition or an autism spectrum disorder.

This Government took the unprecedented step of changing the law to make it possible for adult gender clinics to share medical data with the university. All bar one of the adult gender clinics refused to co-operate with this vital research. To quote Dr Cass, that is “unacceptable”, but I would go even further: I think it is deplorable and a dereliction of their professional duty. I am pleased to update the House that following the publication of Dr Cass’s report, I have been informed that all seven clinical leads for the adult gender services now intend to fully participate in this important work.'

Victoria Atkins, April 2024

'What has emerged in the Cass review is a scandal. It is a scandal that children and young people are waiting far too long—often years—for care while their wellbeing deteriorates and their childhood slips away. It is scandalous that medical interventions have been made on the basis of shaky evidence. It is scandalous that, despite all that, some NHS providers refused to co-operate with Dr Cass’s review. Perhaps the worst scandal of all is that the toxicity of this discussion means that people have felt silenced, and it required investigative journalism to prompt the review to take place. This particularly vulnerable group of children and young people are at the wrong end of all the statistics for mental ill health, suicide and self-harm. '

'The refusal of adult gender services to share data on the long-term experience of patients is inexcusable—as the Secretary of State said, it is deplorable. The data does not belong to them; it belongs to the NHS and, crucially, to patients. I welcome their coming forward now, but how was this allowed to happen, and what accountability does she think would be appropriate?

This report must provide a watershed moment for the NHS’s gender identity services. Children’s healthcare should always be led by evidence and be in the best interests of children’s welfare. Dr Cass’s report has provided the basis on which to go forward'

Wes Streeting, April 2024

Where is all the data that was promised then?

@MalagaNights:

Are children and their parents made aware that many people will never see them as the opposite sex, will not use the language they demand to describe them, and they will have to use the facilities for their sex in SSS.

Once upon a time, back in the early days of so-called sex-reassignment surgery, a patient wasn’t allowed to progress with surgery unless they could demonstrate that they understood the above. They had to show that they knew that the surgery was strictly cosmetic, and that they likely would not be accepted as the opposite sex by the vast majority of the public, otherwise they were not deemed to be sane enough to be allowed to go through with it.

Yes transgender “health” services really need to move completely away from any ideological language. Children should be told that it’s not possible to actually change sex and that any changes are aesthetic/ superficial and that the law as it stands will not permit them to lawfully use the services of the opposite sex.

We know that the waiting list for any kind of psychological treatment means it often just doesn't exist. Nobody pretends that CAHMS isn't over subscribed.

We also know that many children just grow out of gender dysphoria.

What is the rush?

Puberty resolves 80% ofthegenderdysphoria.

If they had a drug that had those results they'd be handing it like smarties.

But because it's essentially, do nothing, watch and wait, it's dismissed. It's the hubris of the medical profession: we must fix this. Instead of: nature has a better solution if we allow it.

They could then see who persists and how to support them.

Puberty is the intervention. It should be obviously preferable to giving everyone medication 80% do not need and which has negative outcomes.

Yes — there are studies, e.g. Wallien & Cohen‑Kettenis (2008) study, which found that among 54 children followed into adolescence/early adulthood, only ~27% retained gender dysphoria or around the figure you state.

But many of those who didn’t continue to meet criteria actually turned out to identify as same-sex attracted or bisexual. That suggests that, for a number of children, the distress may relate to sexuality, social context, or confusion rather than a persistent cross-gender identity. That could be where an initial period of psychological support or therapy might help clarify things.

Also: the diagnostic criteria in those earlier studies were quite broad, and sample sizes small. There is a big difference between transient or mild gender distress in childhood and long-term, severe gender dysphoria which persists despite support or intervention.

To draw an analogy: mild depression in children usually resolves over time without psychiatric medication. But children with severe or persistent depression often do need intervention, and delaying treatment until adulthood could lead to developmental or psychological harm. The same principle applies: not all gender dysphoria is the same, and we should consider carefully who is likely to persist, and when medical intervention might help.

Research suggests that children whose dysphoria does persist tend to have stronger, more consistent feelings of mismatch, described in ways that clearly differentiate them from those whose feelings shift over time.

These are precisely the children who might benefit from more medical intervention such as puberty blockers. That's why trials make sense. Rather than applying a one size fits all go through puberty approach.

Like I mentioned, these children are Gillick competent and absolutely should be told their distress might resolve I.e. with your stats and downsides. They should be told both sides, as should their parents. They are free to withdraw at any point in trials.

How are the children going to be differentiated? What criteria are going to be used to discern the same-sex attracted, or those with trauma-history, from those who appear to have a genuine mental health issue ?

Further to that - why stop puberty? Why not wait until after puberty? What are the 'benefits' to missing puberty?
