"Gender dysphoria" relies on a notion of "gendered essences".
It's a political term created by sexologists that destigmatizes predatory male fetishes by labeling them a pitiable medical condition.
I have come to believe this is not an accident, but was done deliberately.
"Gender dysphoria" is a sex-neutral term which incorporates a variety of conditions - including body dysmorphia among girls - to provide cover for male fetishism.
A belief in "gender dysphoria" does endorse the notion of "gendered essences," and more specifically that a woman can be reduced to a feeling in a man's head, though limited to special, subjective circumstances which can't be measured.
Body dysmorphic disorders do exist, but they are overwhelmingly diagnosed in young women and girls.
In the same vein, paraphilias are overwhelmingly a male phenomenon.
When I see the term "gender dysphoria" I can't help but think of how John Money used the term "gender" to refer to sexual positions, advising that children be shown pornography to help them develop their gender identity.
