PARIS -French female boxers have been barred from competing in the inaugural World Boxing Championships in Liverpool after failing to meet a deadline for a genetic sex test that the French Boxing Federation (FFBoxe) said was incompatible with French law.

World Boxing, which issued a list of competitors for Thursday's opening rounds with no French entrants included, did not immediately respond to a request for comment on the matter.

FFBoxe said it was informed on July 21 that all female athletes needed to provide results of a "femininity test" during registration for the competition, which started on Thursday.

French law prohibits the federation from conducting the tests domestically or abroad without a medical prescription, FFBoxe said, prompting it to turn to a laboratory in Leeds upon World Boxing's recommendation. Despite assurances that results would be delivered within 24 hours, they were delayed:

"With, as a consequence, the exclusion of our athletes as well as other female boxers from foreign delegations who also found themselves trapped," FFBoxe said in a Thursday statement.

"This is a profound injustice," it said. "Our athletes are being punished for a bureaucratic failure and a policy that was communicated far too late."

World Boxing, which will oversee boxing at the 2028 Los Angeles Olympics, introduced mandatory genetic testing in May for female athletes over 18 to confirm eligibility for competition. Its president, Boris van der Vorst, reiterated on Wednesday that it had introduced the tests to ensure safety and fairness.

An FFBoxe spokesperson told Reuters on Thursday it had still not received the test results from the laboratory, which he did not name, and was looking into the possibility of an appeal.

French boxer Maelys Richol said on Instagram a whole year of work had been wasted due to poor management. "It is extremely hard to take. We are frustrated, angry, and deeply disappointed."

The controversy reignited debates surrounding gender verification in sports.
