From everything I read, they are most likely intersex. Outwardly has female traits, but inside is male dominant (including internal testes). Algeria would most likely have jailed them if they were trans, or pretending to be a dude.
Khelif and the other questionable boxer have participated in the Olympics before. Neither have gone undefeated against women, both were disqualified from last year's Women's World Boxing Championships. The other boxer did not appeal, so the decision was final. Khelif appealed, but later dropped the appeal, so that decision was made final as well. The fact that no final appeals went through tells me that the boxers in question know they have some wonky genetic stuff going on. The entity that banned them is Russian led and the Olympic Committee called them corrupt (lol) and is not going by their ruling. So, there is some politics going on here as well.
View attachment 9164 Reminds me of the circus surrounding Caster Semenya. Interesting how differently this is being handled though... ;-) (lol.)
Either way, they should not be competing with females.
