I found that article started off very well and then brought in differences of sex development, by way of a person who found they had XY chromosomes at 33 years old, to confuse the issue. A person who has the phenotype of being a woman, is not a relevant difference of sex development to be mentioned when it has been judged by the IBA that these two boxers have male advantage over female athletes.
For them to have that advantage, they will have gone through a virilised puberty.
Therefore it is irrelevant to bring in a case with a DSD that has not gone through a virilised puberty.
This is not a balanced article. This is an article that perpetuates the utilisation of a very rare group of medical conditions to leverage the established science of sex categorisation for sports.
It is not complex when you can easily do an initial screen using a cheek swab. And then if that shows XY chromosomes, start to do some further testing to check if the body has testes (if no, they are included in the female category), and if the body has any sensitivity to testosterone produced if testes are found (if no, they are also included in the female category).
It is simple. All male people who have any degree of male pubertal advantage should be excluded from the protected category of female sport. Regardless of their history, regardless of their identity.
Testing is available and should be done. The OIC will not because they prioritise inclusion of any male who believes they are a woman to compete as a woman (some need certain conditions to be met such as suppressed testosterone for some events). It is only because of certain new restrictions by some sports federations have that exclude male people with male pubertal advantage that there are not more cases.
