Annelou de Vries and transgender people

Annelou L. C. de Vries is a Dutch psychiatrist who specializes in gender-affirming care for minors. In the 1990s, de Vries pioneered a treatment protocol that required rigid and lengthy psychiatric gatekeeping.

Because of this decades-old conservative protocol, de Vries has become a favored source among cisgender journalists who believe there should be more psychiatric gatekeeping of healthcare for trans and gender diverse youth.

Background

According to a faculty profile:

Annelou de Vries is a child and adolescent psychiatrist working at the Amsterdam UMC/ Levvel Amsterdam Academic Center of Child and Adolescent psychiatry. Her main and special interest is dedicated to transgender adolescents. Apart from her clinical work with these adolescents, Annelou de Vries leads a line of research and publishes and supervises several studies on mental health and treatment evaluation. Annelou de Vries is leading the Child Psychiatry Department of the Center of Expertise on Gender Dysphoria of the Amsterdam UMC. She is president 2023-2025 of the European Professional Association of Transgender Health (EPATH). She co-chaired the Adolescent Assessment Chapter of the World Professional Association of Transgender Health (WPATH) 8th revision of their Standards of Care (Coleman et al., 2022). Annelou de Vries is further full staff member of the department of child and adolescent psychiatry and as such participating in teaching and training of medical students, nurses, and pediatric and child & adolescent psychiatry residents. Her clinical work is further dedicated to adolescents admitted for an intensive OCD, Anxiety and Somatoform symptoms program.

Baudewijntje Kreukels, Thomas Steensma, and de Vries co-edited the 2014 book Gender Dysphoria and Disorders of Sex Development Progress in Care and Knowledge.

The cis journalist narrative

A 2022 piece in Reuters perfectly sums up how cis journalists fetishize de Vries’ overly strict Dutch protocol:

Dr Annelou de Vries, a specialist in child and adolescent psychiatry, is one of the Dutch researchers whose early work established the importance of rigorous patient assessments before starting medical treatment. She said that while she worries about the growing number of children awaiting treatment, the graver sin is to move too fast when puberty blockers and hormones may not be appropriate.

In other words, access to care that might benefit a transgender child is not worth the risk of inadvertently harming a cisgender child.

In 2025, anti-trans activist Azeen Ghorayshi expressed this cis journalist opinion to de Vries in a much less elegant way:

There is this fear that the Dutch approach has been this rigorous… There’s a process for evaluation, assessment is central, and the American affirmative approach and how it has played out in our fractured healthcare system, has somehow endangered everything. That it broke, maybe, something you started.
