First Do No Harm (Day Conference)

First Do No Harm

Critical perspectives on sex & gender in healthcare

Join us at 30 Euston Square, London, for the first conference of its kind in the UK. 

Learn from experts across disciplines – a unique line-up and a day of professional networking

First Do No Harm brings together clinicians, researchers, parents, and therapists to discuss current controversies in the care of children and young people with gender-related distress, safeguarding as it relates to sex and gender, sex-based language in healthcare, and addressing the impacts of gender medicine on same-sex attracted youth.

The current discourse on sex and gender in healthcare is fraught with conflict and political disagreement, and the stakes are high. We bring you a program of speakers with a wealth of knowledge and experience who will bring more light and less heat to these challenging debates.

First Do No Harm will be live streamed.

Keynote speaker  Professor Riittakerttu Kaltiala

Professor Kaltiala is Chief Psychiatrist at the Department of Adolescent Psychiatry, Tampere University Hospital in Finland. As head of a national paediatric gender clinic in Finland, Prof Kaltiala was the first leader in this field to champion a change in policy away from the medicalisation of children and young people with gender dysphoria. Her story is inspirational, and her research continues to bring new knowledge and understanding to this field.


Prof. Kaltiala is an inspiring example of a doctor applying an ethical and evidence based approach to her work and advocating successfully for vulnerable groups. She will talk about her journey from being a leading practitioner of gender transitioning of minors to someone who became profoundly concerned about potential harm, especially to the growing cohort of adolescent girls with complex issues. She advocated for evidence based guidelines ,and a subsequent systematic review of the evidence led to a change in Finnish national policy. Prof. Kaltiala will talk about mental health problems among adolescents presenting with gender dysphoria and implications for treatment.
