Coming back to this now as I've finished the book fully and done a lot more reading about it to educate myself further. I think intersex is the only way she can be described accurately and me labelling her a female was incorrect, but equally, you labelling her a man is also incorrect. She has XY chromosomes so I concede she is biologically male in that sense but she has female external genitalia so I dispute that she is a man. Can you also point me to where it's proven that it was Casters sperm that was used in the insemination process as I didn't see that in the book and she says early on that she cannot contribute to new life and she cannot produce sperm?
I wouldn't go that far as my earlier comment was due to me not being fully educated on the subject (rather than being deliberately misleading) and I concede that my comment wasn't correct.
She was born with internal testes and a vagina externally. I'd say that points to her being intersex so I don't see why the internal testes are more of a defining factor.
One thing that is telling is that despite the perceived advantages of her increased testosterone she only ever ran a 1:54 800m. Keely Hodgkinson has now matched that and the Czech runner with the World Record ran a 1:53. Hardly points to an insurmountable advantage. The actual men generally run 1:40-1:44 at World Class Level so 10-14 seconds than Semenya was able to.
This feels like a science lesson!
The first bolded section is a bit of a contradiction. In mammals, sex is determined by chromosomes & gametes - meaning XY & sperm = male, XX & ova = female. The fact Semenya has testes which produce sperm makes 'her' male/man. 46 XY 5-ARD (5-alpha-reductase deficiency) is a DSD which only affects males - in the same way prostate cancer only affects males. She recently stated in an interview that 'her testicles don't make her any less of a woman'.
The testes are THE ONLY defining factor, they're what make and distribute the male levels of testosterone, the same way as ovaries create the female levels of oestrogen.
As for the advantages, that basically means that Caster Semenya is an average male runner - not a world class female runner. What you're saying is all men should beat all women - it's simply not the case. The same goes for Imane Khelif, he is an average male boxer - the 9 losses he's suffered are because he's an average male boxer, but still has insurmountable advantages over biological females.
I feel for Semenya & Khelif - they didn't ask to be born with these conditions, but the biological fact remains that they're the wrong sex for the category they compete in. 0.00025% of the world's population are diagnosed with 46 XY 5-ARD, yet 3 of them won gold/silver/bronze in the 800m in Rio, does this not prove the massive advantage they hold over biological women?
Anyway, I don't want to ruin this thread with another debate so Ewa Swodoba eh!
