As you can see it made no mention of athletics.

I was curious about the self referential circular definitions and enquired of a specific person what their understanding of development biology was.

Thankyou for your response, it might be better directed toward the person who apparently hasn't yet realised that such a thing as intersex categories and conditions even exist.

I responded to your comment because it was the most recent in the thread, but I agree that it would have perhaps made more sense as a reply to the other commenter.
