Is this a claim worth discussing here, in your view?
(I'm going to go ahead and do so, but interested to hear your answer nevertheless.)
Assuming the IOC (and her family in various interviews) didn't lie about the circumstances of her birth, she was assigned female at birth.
Assuming the IOC issued
correction was not misinformation, they admitted that Khelif "not a transgender case" while disclaiming the original unscripted claim that Khelif was "not a DSD case."
While you are correct that her medical records have not been made public (unless we count
Le Correspondant as a credible source) the DSD hypothesis seems much stronger than the hypothesis that she undertook a course of gender affirmation contrary to her birth sex while growing up in a nation overwhelmingly dominated by Sunni Islam.
