UCLA Student Sues Health Providers Over Alleged Negligence in Gender Transition Care

Clementine Breen, who began transitioning at 12, claims her mental health struggles and abuse history were overlooked in her treatment.

Clementine Breen, 20, has filed a lawsuit against multiple California medical providers, alleging she was rushed into gender transition treatments as a minor without adequate psychological evaluation.
The lawsuit claims Breen, who experienced sexual abuse and mental health challenges, was diagnosed with gender dysphoria at 11 and started on puberty blockers and hormones at 12, followed by a double mastectomy at 14.
Breen states her mental health declined after her transition and believes her underlying trauma and mental health issues were not properly addressed by her healthcare providers.
The defendants include prominent providers in gender-affirming care, such as Dr. Johanna Olson-Kennedy and institutions like Children’s Hospital Los Angeles and UCSF Health Community Hospitals.
The case highlights ongoing debates about medical ethics, informed consent, and the treatment of minors in gender-affirming care, amid rising lawsuits from detransitioners in the U.S. and U.K.
