It seems a bit circular logicky to me - reminds me of this comedian here, he was saying he went to the doctor and said, "I've got an itchy anus." The doctor goes, "Ah, that would be pruritus ani." Comedian guy goes home and looks it up, it's basically just latin for itchy anus...
I mean giving a male who fantasizes about being female a complicated name that just means "male who fantasizes about being female" isn't all that helpful for anything really.
