External sources
External websites that support the critical line of this network — international evaluations, critical scientific networks, parent and detransition platforms, gender-critical women's organisations, investigative journalism and authors. Classified by subject and, where relevant, by country. None of these sites is managed by us.
What this list is
This page lists websites of organisations, research networks, parent groups, writers and media outside our own network. Each source has its own page with a description: who is behind it, in which country the organisation works and what it publishes. The list is arranged by subject, so that you can quickly find the kind of source you are looking for.
Government bodies and evaluations
The sources with the most authority are the bodies that have assessed the evidence for gender care for young people on behalf of a government. In Finland the Council for Choices in Health Care, Palko, did so in 2020. In Sweden the health authority Socialstyrelsen changed the guideline in 2022. In England the institute NICE assessed the studies on puberty blockers and hormones, and NHS England implemented the recommendations of the Cass Review. The British equality regulator, the Equality and Human Rights Commission, plays a role in the question of how facilities that are separated by sex should be organised. These bodies have a statutory task and account publicly for the way they work.
Networks, parent groups and detransition
A second group consists of organisations of doctors, researchers and parents who critically follow the evidence base of the care. They collect studies, write commentaries and organise conferences. In addition, parent groups have emerged in many countries that argue for careful diagnostics and for involvement of the family. An early example is 4thWaveNow, started in 2015 by an American mother. Platforms such as Post Trans collect stories of people who have stopped their transition or have gone back on it, a group that for a long time hardly appeared in research.
Women's organisations and sport
Feminist organisations such as For Women Scotland and Fair Play For Women focus on rights and facilities that are based on sex. For Women Scotland brought the court case that in April 2025 led to the ruling of the UK Supreme Court on the meaning of 'woman' in the equality legislation. In sport, international federations have drawn up their own rules: World Aquatics did so in 2022 for swimming and World Athletics in 2023 for athletics. Both exclude athletes who have gone through male puberty from the female category.
Journalism, authors and publishers
The largest section contains media, investigative journalists and writers. Here the distinction between reporting and opinion matters most. A reconstruction based on documents and interviews is something different from a column, even if both appear in the same medium. Under authors and publishers you will find the writers of books that are described in our archive.
How to weigh a source
Three questions help in assessing any source, including the sources on this page. Who is behind it and who pays for the work? Does the source refer to original documents, such as studies, judgments and reports, so that you can check the claim? And does the source distinguish between what is established and what is an interpretation? Some organisations in this list have a pronounced ideological or political background. That does not make their factual information incorrect, but it is something to know when you read their conclusions.
The sites of our own network are listed under projects, and the most important reports, books and articles are in the archive. How policy has developed in each country can be read under policy by country.
