Dutch developments
For decades, the Netherlands was the global face of gender-affirmative youth care. The Dutch Protocol developed in Amsterdam was internationally regarded as the gold standard. Today, both that protocol and the broader Dutch policy are under heavy scientific and social pressure - although the public debate here still clearly lags behind that in the UK and Scandinavia.
Transgender Act 2024 - self-identification
As of 1 July 2024, the revised Transgender Act is in force. Changing the registered sex has since been possible on the basis of a personal declaration, without an expert statement and without judicial intervention. Critics - including women's rights organisations, lawyers and part of the medical sector - pointed to the consequences for sex-based provisions: women's shelters, sport, prisons, statistics and medical care. The cabinet and the House of Representatives largely set these objections aside. See also the information from the Dutch government.
Explosive growth in referrals
The number of referrals to Dutch gender clinics has increased tenfold since around 2010, with a striking shift: where it used to involve predominantly adult men with early-onset dysphoria, it now mainly involves adolescent girls without any history of gender variance. This pattern, described in the international literature as rapid-onset gender dysphoria (Littman, 2018), is so far in the Netherlands mainly explained as "better visibility", but internationally fits a broader picture of social and media-driven factors.
Amsterdam UMC and the Dutch Protocol
Amsterdam UMC (formerly VUmc) developed the so-called Dutch Protocol from the 1990s onwards: puberty blockers from Tanner stage 2, followed by cross-sex hormones from around age 16 and surgery from around age 18. Internationally this was long presented as evidence-based. The original Dutch studies (De Vries, Steensma) turn out, on re-examination, to have serious methodological limitations: small groups, no control group, heavy attrition, narrow selection criteria, and a death in the original cohort that was not clearly reported in publications. The claim that puberty blockers are "reversible and give time to think" is no longer internationally endorsed; nearly all treated children go on to cross-sex hormones.
International criticism reaches the Netherlands
Since the Cass Review (UK, 2024), the international criticism of the Dutch Protocol has also reached Dutch professional journals. The NTVG published an article on the international criticism of the Dutch Protocol; see the NTVG article. A group of Dutch doctors and scientists publicly argues for a reconsideration of the guidelines and for an independent investigation into Dutch youth gender care, modelled on the Cass Review.
Waiting times and the care system
Waiting times at Amsterdam UMC and other centres rose to several years. Instead of using that waiting time for careful differential diagnostics, the capacity pressure led to a shortening of the pathway and to the rise of private providers operating on affirmative grounds. As a result, the Dutch landscape shifted at precisely the moment when other countries were building in more caution.
Parliamentary attention
In the House of Representatives, there has been increased criticism of the scientific underpinning of youth gender care since 2023. Various parties have submitted written questions about the implications of the Cass Review, the position of puberty blockers, detransition care and the consequences of self-identification. Motions for an independent evaluation of Dutch care policy have been tabled; so far a Dutch equivalent of the Cass Review has not materialised.
Media and public debate
Dutch media long followed almost exclusively the gender-affirmative frame. Since 2023-2024, critical contributions have also appeared in NRC, EW, De Telegraaf and professional journals, including reports on detransition, ROGD in girls and the consequences of self-identification for women's services. At the same time, the debate remains polarising and substantive criticism is still often dismissed as transphobic - which stands in the way of a serious weighing of risks and evidence.
