There are many inconsistencies in the statements that Semenya has made. And through pics such as this, and the topless bathing one.
And that when a pubescent child who was designated female never started menstruating, but developed as if going through male puberty. Did they express concern at this in their biography? And if not? Why not?
The region was known to have a cluster of male people with this DSD from what I have read. I doubt it was unknown by the community. So, I believe there is enough inconsistency to cast doubt on Semenya’s words.
And it does shine significant light on their disparagement of the female athletes they beat.
