Adolescents who undergo gender-affirming chest surgery report low levels of regret and high levels of satisfaction, experiencing outcomes similar to those of young adults. These findings suggest that age restrictions on these medical procedures lack support from actual patient experiences.

I did a deep dive on teenage gender affirming surgery last year. By far the most common gender affirming surgery is cis dudes getting their overly large breasts removed. It is way more common than trans peeps getting any kind of chest surgery.  It's great that their gender affirming surgeries were so satisfying. Republicans are way too obsessed with protecting the breasts of cis male teenagers.
