Rapid-onset gender dysphoria controversy
Rapid-onset gender dysphoria (ROGD) is a controversial, scientifically unsupported hypothesis which claims that some adolescents identify as transgender and experience gender dysphoria due to peer influence and social contagion, particularly those assigned female at birth. ROGD is not recognized as a valid mental health diagnosis by any major professional association.
