Now Jiu Jitsu sparks gender row as male fighter controversially kisses his 6ft 2in female opponent before choking her out in the sport’s first mixed sexes bout

Algerian boxer Khelif, 25, who is not a transgender woman, allegedly has male ‘XY chromosomes’ which led to her disqualification from 2023 world championships.

At the time she and Lin failed unspecified gender eligibility tests administered by the now-banned International Boxing Association, with the International Olympic Committee instead taking charge of the boxing events at Paris 2024.

Some sports have limited the levels of testosterone allowed for athletes competing in women’s competition, while others ban everyone who has been through male puberty.

Differences of Sexual Disorder are a group of rare conditions involving genes, hormones and reproductive organs.

Some people with DSDs are raised as female but have XY sex chromosomes and blood testosterone levels in the male range.

The IOC said its rules of eligibility were based on those of the Tokyo Games in 2021 and could not be changed during a competition.

Tech billionaire Elon Musk and Harry Potter author JK Rowling were among the high-profile figures leading the outcry about Khelif taking part in this summer’s Games at which the Algerian fighter won gold.

Now Khelif has filed a lawsuit to French authorities alleging ‘acts of aggravated cyber harassment’ – and the potential penalties at stake have now been revealed, as well as the prospect of yet more famous names being targeted.
