Ok, it's the presence of the SRY gene. That doesn't really change what I said. Gender is determined at the DNA level, not by hormones or sex changes. I'm not aware of the specifics of the contestant's genetics, but most sex-changes are done to perfectly normal XY, and XX-chromosomed people. I mean the SRY gene doesn't turn a penis inside-out. The olympics bans anyone with the SRY gene from participating in female events, as that's the general scientific definition of gender.
