I think it was referenced many pages ago, but I finished "Tested," the very informative podcast from NPR and CBC about athletes with DSDs. It first details early efforts and motivations to do sex testing, such as the surprisingly short-lived (about two years) "nude parades." There also appears to be a documentary on the topic called "Category: Woman."
I'd say it's worth everyone's time. I was kind of curious what other people thought of it so I looked at some reviews. Most were very positive, though one said it "offered no solutions other than to reinforce a narrative of oppressor and oppressed." I'm honestly not sure what you would do to solve that at this time. The CAS decision (which includes an audio clip) basically declared "yes, this is discrimination but it's necessary discrimination to protect the female category" and it appears that the stance of World Athletics and CAS is that if you want to compete you can chemically mutilate your body or else, tough ship. I'm not sure how you fight that other than perhaps to try and get an injunction against the organizers of a meet and World Athletics on the grounds of unlawful discrimination, and even then I think CAS largely exists as a sort of binding arbitration that prevents things exactly like that from happening (i.e., global organizations being dragged into domestic courts) and to do that would be the sort of "government interference" that organizations like that tend to frown upon.
The podcast touches on this, though not as much as they probably could, but I think they could have gone more into the fact that racism and sexism have a pretty significant role in these debates. As I mentioned a while ago, a significant number of the women caught up in these issues are from sub-Saharan Africa, including all three medalists from the women's 800 (South Africa, Burundi, Kenya) in Rio. Shifting gears a little, which American female athlete's gender is most frequently called into question? Brittney Griner. Not every DSD athlete is going to look and talk like Caster Semenya. I kind of get the feeling that a lot fewer people would care about "protecting women's sports" from athletes from the global south and who look like Semenya than they would care about "protecting women's sports" from someone who is from a major country and looks like Keely Hodgkinson, no matter what her chromosomes look like. And considering how much of women's athletics and how many administrators of women's athletics deliberately target the male gaze, I kind of wonder how much some of these athletes (including the boxers) are guilty of being fast, non-white, poor and conventionally unattractive.
