Note that we don't know what kind of test the IBA used to disqualify the two Olympic boxers. You say "karyotype test" because the sports journalist above reported "male karyotype" as the "interpretation" of the test result, without specifying the test (probably because the sports journalist doesn't realise "chromosome test" is vague and imprecise). That doesn't tell us what kind of test was carried out and there is no official information, because it would be illegal to share it. It seems the IBA was planning to share the results but the two athletes' teams sent legal letters to the IBA reminding it of non-disclosure agreements:

The purpose of the press conference was to double down on the IBA’s claim that the IOC, led by Kremlev’s bete noire, Thomas Bach, is a danger to women’s boxing, among other things.

It had been believed making public the chromosome tests of the boxers would place serious pressure on the Olympic organisers’ position that the fighters were eligible having been registered as women at birth and holding passports as such. But that morning legal letters came in from the Algerian and Taiwanese organising committees warning them not to breach non-disclosure agreements.

So all we have to go by is, frankly, dodgy tactics by the IBA that seems more interested in kicking up a storm to discredit the IOC, than to protect women's sports. I suggest caution in accepting anything the IBA says.
