Imane Khelif filed an appeal against World Boxing at the Court of Arbitration for Sport (Cas).
The world federation banned her from competing without a genetic test at upcoming events.
World Boxing ruled that all women competing at the World Championships in Liverpool, from September 4 to 14, must undergo sex testing.
Khelif submitted her appeal on August 5 and demanded permission to compete without a test.
She also requested suspension of the testing rule until a verdict, but Cas rejected this on Monday.
Cas announced a hearing but did not provide a date for the final judgment.
World Boxing justified the testing requirement as protection for athletes and a guarantee of fair competition between genders.
The federation demanded that all female athletes over 18 complete a one-time PCR or equivalent genetic test.
Controversy sparked after Olympic Games
The debate began at the Paris Olympics over Khelif and Lin Yu-ting from Taiwan.
Both boxers were excluded from the 2023 World Championships by Iba after unspecified sex tests.
Iba argued they held unfair advantages compared to other women and failed to meet participation rules.
The IOC condemned the decision as arbitrary and allowed both athletes to compete in Paris.
The IOC explained that passport gender determines eligibility for competition.
Khelif and Lin both won gold in Paris, igniting a global discussion.
IOC turns to World Boxing for future events
The IOC recognized World Boxing in February as an official partner for the sport’s future.
After suspending Iba, the IOC organized Olympic boxing tournaments in Tokyo and Paris itself.
For Los Angeles 2028, the IOC will hand responsibility for Olympic boxing to World Boxing.
