There is no evidence for rapid-onset gender dysphoria (ROGD). It is the equivalent of phrenology, a load of garbage used to attack and deny the existence of Transgender youth, to justify torturing them and driving them to suicide by denying health care.
You can be sure that TERF trash and other anti-Trans bigots will quote unqualified quacks and deny that the University of Western Ontario is a credible source of research. The original paper can be read here.
A first-of-its-kind study by Schulich Medicine & Dentistry researchers dispels a controversial gender dysphoria theory that activists and experts have called inaccurate and harmful to transgender people.
Greta Bauer, Ph.D., and her team at Trans Youth CAN! found no evidence in a recent study to support the idea of rapid onset gender dysphoria (ROGD)—a proposed condition often used as an argument against providing gender-affirming medical care to young people.
“It’s impacting policy, and there is no research on any actual adolescents that supports this hypothesis,” said Bauer, professor in the department of epidemiology and biostatistics at Schulich Medicine & Dentistry and the CIHR Sex and Gender Science Chair.

In 2018, researchers in the U.S. claimed ROGD was a unique pathway in which youth going through puberty experienced sudden gender dysphoria influenced by social and peer contagion along with other factors including poor mental health or parent-child conflict.
Bauer said that paper has “taken on a life of its own” in the three years since its publication, purporting that youths’ gender identity could be influenced by their queer peers and fuelling the notion that young people might identify as trans or non-binary as part of a temporary phase.
“The ROGD hypothesis perpetuates the fear that says, ‘you shouldn’t let your kids hang out with trans people.’ It’s harmful,” Bauer said. “Socially, that’s a really horrible message and ostracizing for youth who are trans or non-binary.”
The only thing that exposure to Transgender people did to Transgender kids was tell them they’re not wrong, that it’s not a “fad”, “transtrending” or akin to “contagious suicide”.
Transitioning saves lives. That’s why bigots oppose it, they want Transgender and Non-Binary people to die.
