I believe it refers to:

Conversion therapy is a practice that aims to change an individual's sexual orientation to heterosexual or gender identity to cisgender, which means identifying with the sex assigned to them at birth.

It employs various approaches, from talk therapy and medication, to aversion therapy that attempts to condition a person's behaviour by causing them discomfort through things like electric shocks when they're exposed to specific stimuli.

It is believed conversion therapy has existed for more than a century, with German psychiatrist Albert von Schrenck-Notzing being one of the first to use the practice on patients.

I don't believe this will target people with Body Dysmorphia. They are still going to be free to change their orientatins and physical genetalias.
