You've failed to mention an important point: since tighter WA rules for XY DSD athletes in women's competition came into effect after the Court of Arbitration for Sports ruled on the Semenya case in mid-2019, a considerable number of athletes covered by the rules stopped competing altogether.
For example, in the wake of the Semenya decision, Athletics Kenya immediately announced it was dropping a number of runners who were already competing on the Kenyan women's national squad, or were promising hopefuls coming up the ranks, for having testosterone above the upper limit that WA then put into place (5 nmol/L). (Some of these athletes were XY DSD; others appear to have been doping).
In certain countries in sub-Saharan Africa, athletes with XY DSDs are so disproportionately represented in elite women's track and field - and in other major sports like soccer - that there's good reason to suspect that coaches and athletics organizations in those countries have intentionally searched for, scouted and trained such athletes for the express purpose of putting them into women's competition so they can use their leg up over female athletes to have a much easier chance at winning gold and glory.
In India, women's track & fieled legend PT Usha and others say there's usually a disproportionate number of XY DSD athletes in the junior ranks of girls' and women's elite track & field. But sports officials in India have long made a point of trying to identify XY DSD athletes and weed them out of girls' and women's competition before they make the big-time in women's world championships and other major adult international events. Which is why Dutee Chand sued Indian sports officials for declaring Chand ineligible for women's competition after requiring Chand to undergo medical sex testing in 2014.
By contrast, sports offficials in a number of sub-Saharan African countries seem to go out looking for XY DSD athletes they can enter into women's events and turn into stand-out sports stars by having them compete against and admist females.
Last year, for example, 11 soccer/football players on sub-Saharan national women's squads including Olympic superstar Barbra Banda were declared ineligible for the 2022 Women's Africa Cup of Nations championship reportedly for having XY DSDs and not adhering to the Confederation of Africa Football and FIFA regulations requiring that their testosterone be reduced to a certain level in order to be eligible for certain international women's competitions. One country had 4 such athletes on its first-string national women's squad.
Then there's the case of Namibian XY DSD runners Christine Mboma and Beatrice Masilingi, two same-age runners from very poor, remote areas of rural Namibia who just happened to be discovered and put on the path to greatness in women's competition at the same time by the same coach, Henk Botha. After spotting and scouting the "two turbo teens" as the Namibian press has dubbed them, Botha and other men high up in the world of Namibian sports, government, politics, business and media arranged for Mboma and Masilingi to be fast-tracked to stardom in elite international women's running and turned into widely celebrated Namibian national heroes - investing time, money and attention on the two XY DSD athletes that no female athletes in Namibia have ever received.
