Okay, I had to check out the terminology that the Olympics use and it appears that these athletes are subjects of Swyer Syndrome:
Swyer syndrome is a condition that affects sex development. Explore symptoms, inheritance, genetics of this condition.

They often develop vaginas and even a working uterus, but they have no ovaries. Instead their testes are in roughly that location.
'People with Swyer syndrome have female external genitalia and some female internal reproductive structures. These individuals usually have a uterus and fallopian tubes, but their gonads (ovaries or testes) are not functional. Instead, the gonads are small and underdeveloped and contain little gonadal tissue. These structures are called streak gonads. The streak gonadal tissue is at risk of developing cancer that is often hard-to-detect, so it is usually removed surgically. Swyer syndrome is also called 46,XY complete gonadal dysgenesis; the medical term “dysgenesis” means "abnormal development." '
So demands that these athletes strip to be called "woman" would not change anything. They would still look just like other women, at least down below. I do not think that these individuals had their internal testes removed and that is likely the source of their high testosterone levels.
The question is "what is fair"?
