The gist
New Zealandโs Ministry of Health was warned it could be breaking the law by publicising the off-label use of hormone suppression drugs to interrupt the puberty of transgender-identifying children.
The governmentโs own regulator, Medsafe, raised this risk last September when ministry officials were discussing a more cautious website reference to puberty blockers.
The ministryโs website previously had claimed these drugs were โa safe and fully reversible medicineโ for children with gender distress. Known as GnRH analogues, these hormone suppression drugs have various approved uses; trans puberty blocking is not one of them.
โIf the ministry advocated that certain medicines be used off-label, this could come in for criticism as a potential breach of the [Medicines Act 1981],โ Medsafeโs manager of compliance, Derek Fitzgerald, said in an email exchange with ministry officers obtained under the Official Information Act by Simon Tegg of the group Fully Informed.
Section 20 of the Medicines Act prohibits the advertising of an off-labelโor unapprovedโuse of a medicine.
A legally qualified health practitioner, who looked into this issue and spoke on condition of anonymity to avoid harassment by trans activists, told GCN that in her opinion there is no question but that the ministry is in breach of the Act.
โThe [ministry] should be a trusted source of healthย advice,โ she said.
โThe fact that this particular drug, used in this way, is specificallyย prescribed to disrupt a normal and important physiologicalย process in childrenโpubertyโthat alone should attract a very high standard of scrutiny.โ
In 2022, there were 771 minors prescribed drugs to suppress natural hormones, a rise of 462 per cent since 2012, according to data from the medicine-funding body Pharmac reported this month by the NZ magazine Listener.
In the same magazine last year, emeritus professor of epidemiology Charlotte Paul wrote that she was โsurprised to discover that puberty-blocking hormones are not approved for use for [the distress of] gender dysphoria, not by Medsafe here [in New Zealand], nor by the US Food and Drug Administration, nor the European Medicines Agency.
โIt is probably because there is simply insufficient evidence available about benefits and harms. It also means that extra precautions are required.โ
Last September, when Medsafeโs Mr Fitzgerald cautioned health ministry officials about public statements on puberty blockers, he said it was โimportant to note that where potentially controversial matters are concerned, there may beย extra scrutiny of the legality of the ministryโs actions.
โYou may wish to obtain a legal opinion on the information the ministry publishes/wishes to publish on this.โ
The penalty for an individual advertising an unapproved drug use is a maximum prison term of six months or a fine up to $20,000; for a body corporate, the maximum fine is $100,000.
A spokesman for the ministry told GCN that in publishing information on puberty blockers, โthe ministry is satisfied that it has complied with the law at all times.โ
The legally qualified health practitioner who spoke to GCN noted that the ministry administered the Medicines Act and said this raised โthe problem of the ministry marking its own workโ in determining whether or not it had breached the Act.
The ministry did not answer when asked if it had acted on Medsafeโs suggestion to seek legal advice.

The detail
The NZ health ministryโs updated public statement on puberty blockers, which now appears on a Health NZ webpage, reads in partโ
โPuberty blockers are a medicine that can be used to halt the progress of potentially unwanted puberty-related physical changes. Blockers are sometimes used, with the guidance of a clinician who specialises in their use, from early puberty through to later adolescence to allow time to fully explore gender health options.โ
Before September last year, the ministryโs reference had saidโ
โPuberty blockers are a medication that can be used to halt the physical changes of an unwanted puberty. Blockers are a safe and fully reversible medicine that may be used from early puberty through to later adolescence to help ease distress and allow time to fully explore gender health options.โ
Despite the shift to more cautious wording, both references amount to the advertising of an unapproved drug use and are in breach of the Medicines Act, in the opinion of the legally qualified health practitioner.
She said this was the case notwithstanding ministry officials having decided to remove some clinical detail and the specific puberty blocker drug names, Leuprorelin and Goserelin, when drafting the new website reference. These cuts were made partly to accommodate Medsafeโs warning of a potential breach of the law.
โThe Royal New Zealand College of General Practitionersโฆ appears to support puberty blockers for gender dysphoria, saying they can help to reduce distress and allow time for young people to mature before making decisions on permanent gender-affirming optionsโโjournalist Ruth Brown, news report, Listener, 13 May 2023
โMedical director Dr Luke Bradford says a core principle of medicine is first do no harm, but โnot starting blockers where beneficial, should not be considered a neutral act, with the risk of lifelong unwanted physical changes causing distress and the potential for a negative impact on mental healthโ.โ
Evidence check
Last September, taking into account growing concern about puberty blockers in Sweden and other European countries, the NZ health ministry ordered the preparation of an โevidence briefโ on this treatment for the condition of gender dysphoria, in which a distressed young person rejects their birth sex.
The evidence briefโput together by the evidence, research and innovation branch of the ministry, potentially in consultation with outside expertsโwas reportedly due for release this month. GCN has sought confirmation of this timing from the ministry.
Hormone suppression drugs known as GnRH analogues are used internationallyโwithout regulatory approvalโto interrupt the natural puberty of children who identify as trans or non-binary.
โDoctors have wide prescribing rights. These rights are only limited by their scope of practiceโbut patients have rights too,โ the legally qualified health practitioner said.
She pointed out that โMedsafe,ย the Medical Council of NZ, and the Health and Disabilityย Commissioner all advise that a higher standard of consent is required when the doctor is prescribingย an off-label medicine.โ
Approved uses for GnRH analogues include central precocious (or premature) puberty, prostate cancer and endometriosis.
Gender clinicians and activists suggest that the longer history of premature puberty suppression should reassure sceptics of trans puberty blocking, but this analogy has been rejected as misleading by Englandโs Cass review of gender dysphoria care.
Suppressing the natural puberty of children who identify as trans or non-binary arouses strong disagreement within medicine; treatment is sometimes begun as young as 8-10 years of age. Known side-effects include low bone density, while the effect on the developing adolescent brain is unknown.
โIn New Zealand, the Medical Council issues guidelines for unapproved medicines, or those unapproved for particular uses. Unapproved medicines must be subject to monitoring, to prior discussion with a senior colleague, and the patient must be given extra information about risks and benefitsโincluding that the medicine was being prescribed for an unapproved indication. None of this (apart from monitoring height and bone density) is mentioned in the New Zealand guidelines for gender-affirming healthcare [issued in 2018 by the Professional Association for Transgender Health Aotearoa]โโProfessor Charlotte Paul, Listener, 3 September 2022
Gender insiders
Last Septemberโs email exchange involving ministry officials also shows that New Zealandโs Professional Association for Transgender Health Aotearoa (PATHA) wanted a โgender-affirmingโ clinician to be involved in reworking the ministryโs public reference to puberty blockers. It appears that the drafting was too far advanced for this intervention.
Like its international counterpart WPATH, PATHA is a hybrid professional/trans activist lobby; the gender-affirming treatment approach promoted by PATHA is controversial.
PATHAโs 2018 treatment guidelines claim that, โPuberty blockers are considered to be fully reversible and allow the adolescent time prior to making a decision on starting hormone therapy.โ
From 2020 until the September 2022 change in wording, the ministryโs webpage linked to this PATHA document. It was not clear who had requested the link, according to an email exchange within the ministry last August.
โThe Ministry of Health has not gone through any formal process to review or endorse the PATHA guidelines,โ a spokesperson said recently.
โ โ[Trans hormone suppression] was sold as a kind of pause button, allowing you to put puberty on hold while you can think about whether you are really in the wrong body. Thatโs the theory.โ Patrik Vankrunkelsven, director of the Belgian Center for Evidence-Based Medicine, strongly questions that so-called โreversibilityโ โโnews report, VRT
โ โWe now see that 98 per cent go through with the transition [after starting on blockers]. Claiming that it is reversible, or a pause button, is just not right. Puberty inhibitors are a trap that kids get stuck in, denying them the chance to change their mindโ.โ
Systematic
Apart from the evidence brief to be published on the ministryโs website, deputy chief science advisor Dr Sayali Pendharkar suggested in the August-September 2022 email exchange that, โWe should undertake a formal systematic review and meta-analysis on evidence-to-date on puberty blockers similar to UK, Sweden, Finland.โ
(This discussion of NZโs own systematic review was put off, however, with the officials concentrating on the immediate task of updating the website reference to blockers and commissioning the medium-term evidence brief.)
In an email last September, Dr Pendharkar also advised a โconversation with PATHA to update their guidelines (dated 2018) particularly in light of the NICE review.โ
The 2020 review by the UK National Institute for Health and Care Excellence (NICE) contributed to the review of dysphoria care led by paediatrician Dr Hilary Cass.
In its search of the medical literature for evidence on puberty blockers, NICE found 525 references, but after screening for quality, only nine studies were eligible for review. Even with these studies, the results were rated as โvery low certaintyโ.
A systematic review is the gold standard for assessing the quality of evidence while minimising bias, and would carry more weight than an evidence brief.
Swedenโs review led to a new, more cautious policy on gender medicine in 2022, as well as a paper published last month in the journal Acta Paediatrica, with corresponding author Professor Mikael Landรฉn of the Karolinska Institute and University of Gothenburg.
โAgainst the background of almost non-existent long-term data, we conclude that GnRHa [puberty blocker] treatment in children with gender dysphoria should be considered experimental treatment rather than standard procedure,โ Professor Landรฉn said in a media statement.
โThis is to say that treatment should only be administered in the context of a clinical trial under informed consent.โ
Note: GCN sought comment from PATHA
Melbourneโs Royal Childrenโs Hospital Gender Services websiteโs version of the reversibility of puberty blockers:
Puberty blockers suppress the development of secondary sex characteristics and are used for adolescents in the early stages of pubertal development. As they are reversible in their effects, should an adolescent wish to stop taking them at any time, their biological puberty will resume.
Compared with the new-found caution from the NZ Ministry of Health:
The governmentโs own regulator, Medsafe, raised this risk last September when ministry officials were discussing a more cautious website reference to puberty blockers. The ministryโs website previously had claimed these drugs were โa safe and fully reversible medicineโ for children with gender distress. Known as GnRH analogues, these hormone suppression drugs have various approved uses; trans puberty blocking is not one of them.
