No, the same thing as I said before. There are 2 "female athletes" who look like men. One agency has disqualified them for gender reasons. The other one has accepted them. The genetic information is not disclosed. People don't get DQ'd for gender for no reason. It's the IOC being too lax.It boils down to health information privacy. Gender related information seems to be a touchy subject around the world. The IBA is notorious for being corrupt, if they have a legitimate case they can easily publish the report on why those athletes were disqualified, the fact that they haven't shows that they do not have a strong case vs the IOC.
Genetically speaking, there is only 1 situation in which they can be cleared and that's if all the tests have been run and there is nothing that differentiates them from normal women. I doubt this is the case or there could never have been a disqualification in the first place by any agency.
In genetics, we are all set on the path to become women when we are conceived. Androgens produced by genes active on the Y chromosome will pull males apart from the path to become female onto the path to become male. If a person is XY with a female phenotype, it means that either the production of those androgens have been stalled or that the receptors making the body react to them have been mutated. In this case, they may be inactive, resulting in a pure female phenotype or they may be partially active resulting in an ambigious phenotype when that path is pulled towards the male path but not completely there. The latter is the case with the 2 athletes in contention. There is also the case of an XX female who is obviously masculine and has very high levels of androgens. Shouldn't this person be allowed to compete as a female because she's XX? No. Because the reason she has these abnormally high levels is because she has a part of a Y chromosome inside her X chromosome! When her father's gametes underwent meiosis, during recombination, part of his Y recombined onto his X and that X was passed onto her. So she is still partially male. Because we are all by default female at conception, there is virtually no situation where a true female can come to resemble a male as that would require multiple "gain of function" mutations that mysteriously start to produce specifical hormones that are NOT in her genome to produce.
