About Us

We are a growing group of international professionals with expertise in a range of clinical and academic disciplines who share a deep concern over the lack of quality evidence behind the increasing use of frequently irreversible hormonal and surgical interventions as the first line of treatment for young people with gender-dysphoria.

Gender-dysphoric and questioning individuals deserve respect, compassion, and high-quality medical care. Join us in our mission to promote evidence-based care for gender dysphoric children, adolescents, and young adults that prioritizes long-term outcomes, and is free from undue political, ideological, religious or financial influences.
