Look number one, whether or not she is xy has not been confirmed. It was reported by a Russian controlled organization only after she beat a Russian fighter, and they haven't actually released their results or methods.
Second, what the posted article is referring to, if she was indeed xy (which is just suspect Russian heresay at this point), is androgen insensitivity syndrome. Meaning she wouldn't be able to derive benefit from testosterone anyways. This is also different from trans individuals on a number of levels. Though Russia of course sees it as beneficial both for smearing anyone that beats their own athletes, as well as stoking popular lgbt hatred in their own country.
The only story here is Russia co opting international sports organizations for their own purposes once again, just like when they had state organized doping of their athletes that went all the way to the top involving the flipping FSB. Now they are also using it to try and spread fear and hate of trans individuals, even though it wouldn't be trans in this case it would be intersex if what they said is true, and we have no actual confirmations that she is intersex anyway. I'll believe it when an organization not controlled by Russia shows it (and even if they were correct it's very likely she wouldn't be deriving any advantages from it).
They've made similar unsubstantiated claims against another boxer. They still haven't released any specifics of their testing, and they only made these claims after they claimed world championship titles in each case. What a coincidence.
I doubt either of them is actually xy. This Russian boxing organization was banned by the international community for good reason.
Welp we'll find out how low the supreme court wants to go I suppose
