- Karotype testing of Khelif (and the other disqualified boxer, Lin) showing XY chromosomes, reported by sports journalist Alan Abrahamson who's seen the lab reports and covering letter that was received by the IOC from the IBA: https://www.3wiresports.com/articles/2024/8/5/fa9lt6ypbwx5su...

- A member of Khelif's training team, Georges Cazorla, revealing in interview that Khelif has problems with chromosomes and hormones, and has been under testosterone suppression to bring levels into the female range: https://www.lepoint.fr/monde/2024-olympics-imane-khelif-was-...

- Extracts from a medical report leaked to French journalist Djaffer Ait Aoudia, which state that Khelif has a disorder of sex development, 5-alpha reductase deficiency, which exists only in males: https://lecorrespondant.net/imane-khelif-ni-ovaires-ni-uteru...

There are other oddities as well, like Khelif choosing not to pursue a case at the Court of Arbitration for Sport after being deemed ineligible to compete in IBA events. And the head of the Spanish national team, Rafael Lozano, saying that when the Algerian team visited to train, they ended up matching Khelif with a male boxer to spar, as the upper body strength and punching power was too much for the female boxers.

Worth noting also that all this is consistent with Khelif competing at the Olympics in the women's boxing category, as they only ask for identity documentation and do not verify sex, unlike weight classes which are strictly controlled.
