Significant methodological flaws in existing research
One study of 14 postsurgical youth (nine of whom were under 18 years) found that “all reported high aesthetic satisfaction and most self-reported low complication rates and improvement in mood.”
Another cross-sectional retrospective survey looked at 68 postsurgical transmasculine youth (72% of the eligible postsurgical population); 49% had surgery when younger than age 18, with the youngest being age 13 and the oldest age 24. At the time of the survey, only 14% of participants were more than 2 years postsurgery. The postsurgical participants were found to have reduced chest dysphoria (the outcome) compared with a convenience and nonmatched comparison sample of nonsurgical transmasculine youth.
And a 2021 qualitative study of 30 transmale youth – about half of whom had undergone chest surgery – concluded that the postsurgical cohort experienced “tremendous” benefits in chest dysphoria and a range of psychological outcomes.
On this particular study, Ms. Clayton notes that “in my opinion, they did not provide enough detail for the reader to make an informed judgment regarding this latter claim.”
She goes on to discuss genital surgery, sometimes called full gender-affirming surgery (or “bottom surgery”), and says proponents of these operations point out that the main objections to them in minors is to “surgical sterilization, and people get super worked up about that ... it is a barrier we have to overcome, and I think we are going to.”
Ms. Clayton asserts that it seems “this barrier is already being overcome, as it has been reported that in the United States, genital surgery is being undertaken on gender dysphoric minors as young as 15 years old.”
Reflecting on the available evidence, Ms. Clayton highlights the significant methodological flaws that limit the extent to which surgery can be linked to short-term improved mental health outcomes and adds that information on long-term outcomes and rates of regret is unavailable.
She also asserts that the research fails to assess “a role for psychological interventions which could be utilized, as a least-harm intervention, until maturity is reached.”
Historical examples of experimental medicine
Ms. Clayton goes on to draw parallels with experimental medicine performed on homosexuals in the 20th century, highlighting the medical and surgical interventions, which included metrazol convulsive therapy, chemical castration with estrogens, surgical castration, clitoridectomy, brain operations, and aversive electrotherapy.
She also refers to the historical practice of hormonal treatment for “tall girls” and “short boys” between the 1960s and 1980s. Hormones were given to young people who did not have any medical reason underpinning their stature but were distressed, and society considered their height to have a negative social impact.
“With the encouragement of physicians and school nurses, enthusiastic media promotion, and pharmaceutical companies’ advertising, parents sought hormonal interventions,” she writes, adding that, at the time the hormones were considered safe, but long-term adverse effects emerged, including impaired fertility and increased risk of cancers.
“This seems another part of the story of medicine acting to reinforce society’s sex stereotypes, and for some patients it came at disastrous personal cost,” writes Ms. Clayton.
The gender-affirming approach is based on endorsing the adolescent’s stated gender identity with minimal questioning and “that they should be supported to undertake social transition, medical transition, masculinizing chest surgery, and, some also argue, genital surgery,” she writes.
Objectors to this approach pinpoint the “limited and low-quality evidence base for the benefits” but also “the irreversible and long-term adverse impacts of these treatments on fertility and sexual function, as well as on bone, brain, and cardiovascular functioning.”
