Taiwan’s Lin Yu Ting and Algeria’s Imane Khelif both failed gender tests, including testosterone tests. Each boxer came back as XY chromosome. Human females have two X chromosomes.

The boxers were disqualified from the Women’s World Boxing Championships in New Delhi last year.

“Based on DNA tests, we identified a number of athletes who tried to trick their colleagues into posing as women,” the president of the International Boxing Association, Umar Kremlev, told Russia’s Tass news agency last year. “According to the results of the tests, it was proved that they have XY chromosomes. Such athletes were excluded from competition.”

But the Olympic committee is allowing them to fight women in their weight class during the Paris Olympics.

Both boxers beat the best women in their countries to qualify for the Olympics in Paris.

Khelif and Lin have always competed as women. Neither man has claimed to be transgender or intersex.

Following his disqualification last year, Khelif told Algeria’s Ennahar TV that some countries “did not want Algeria to win a gold medal.”

“This is a conspiracy and a big conspiracy, and we will not be silent about it,” Khelif said.

Critics condemned the Olympic committee for allowing Khelif and Lin to fight in this week’s competition.

However, none of the female boxers seem to be complaining.

Khelif is scheduled to fight Italy’s Angela Carini on Thursday, and Lin is scheduled to go to-to-toe with Uzbekistan’s Sitora Turdibekova on Friday.
