I don't think they've revealed whether Imane Khelif has a female reproductive system. A recent past Olympic athlete with the same syndrome, Caster Semenya, does not have full female reproductive organs. However, both of them externally present as female with XY chromosomes. Semenya had been required to take testosterone blockers to reduce her testosterone, puzzlingly, to a level less than required for actual transwomen.
I'm not in favor of transwomen competing against natural biological women. However, I'm not concerned about people with this syndrome competing against biological women. This is, to me, not dissimilar from the 7.6 foot basketball player Yao Ming, and ultimately will have no more effect on the sport. These are two clearly outlier cases that don't have any real impact on the discussion of transwomen competing against biological women. The existence of the platypus does not change the definition of a duck.
