California Doctor Sued Over Alleged Negligence in Youth Gender Transition Case

A detransitioned UCLA student claims she was rushed into irreversible medical procedures starting at age 12 without adequate mental health evaluation or informed consent.

Clementine Breen, a 20-year-old detransitioned woman, has filed a lawsuit against Dr. Johanna Olson-Kennedy and others for medical negligence during her youth gender transition.
The lawsuit alleges Breen was prescribed puberty blockers at 12, testosterone at 13, and underwent a double mastectomy at 14, without sufficient mental health evaluation or informed consent.
Breen's history of sexual abuse and mental health struggles was reportedly overlooked, with claims her parents were pressured into agreeing to the treatments under misleading information.
Dr. Olson-Kennedy has faced criticism for withholding findings from a taxpayer-funded study, which reportedly showed no mental health benefits from puberty blockers, citing concerns about the data being misused.
The case is part of a growing wave of legal challenges against medical professionals over youth gender transitions, as scrutiny of such practices intensifies in the U.S. and abroad.
