Swiss detransitioner Chris Brönimann now opposes gender-affirming care for minors
Chris Brönimann, once Switzerland's most prominent trans man, has publicly detransitioned after 29 years. He now identifies as male again and has spoken out against medical gender transitions for minors. His shift in stance has sparked both support and backlash.
Brönimann first announced his detransition in autumn 2024. Before this, he had lived as Nadia for nearly three decades after undergoing gender-affirming surgery. By late summer of that year, he had briefly questioned the binary gender system but now rejects the idea of being non-binary.
He describes his original transition as 'extreme, boundary-crossing abuse' of his healthy body. His regret over the decision has led him to advocate for banning puberty blockers and hormone treatments for minors. He argues that young people should be protected from making irreversible changes during the 'turbulent years of puberty'.
Brönimann's views have drawn criticism, particularly from parts of the trans community. He has reported facing 'rejection and hatred' since sharing his position. Despite this, he continues to speak publicly, stating that 'truth is not found in the mirror, but in the soul'.
Public records up to early 2025 show no documented cases where Brönimann has directly named individuals or organisations in his criticism of gender treatments for minors.
Brönimann's detransition and outspoken stance have placed him at the center of a contentious debate. His call to restrict medical transitions for minors remains a polarizing issue. The discussion around his experience reflects wider disagreements over gender-affirming care for young people.
