To want to know it the IAAF are going to introduce upper levels of endogenous testosterone for male athletes?

Totally horrified by the ruling on Caster Semenya which essentially robs her off her career and penalises her for the strength and power that is her birthright as a human being.

The justification for this is that her testosterone levels put her beyond an acceptable upper limit to qualify to compete as a woman (while of course she remains prohibited from competing as a man).

So I want to know at what level of testosterone naturally present male athletes will be ruled out of the human race? Or is it only women who can be too strong,too fast, too good to be allowed to compete in their category?

Yes, as they were saying on the radio, how is it different to a tall basketball player or a swimmer with extra large feet? It's a natural difference which gives a sporting advantage.

Unless if they have just one competition that is open to everyone, then there has to be criteria for the split. Mental gender seems an odd choice for a split in a physical competition. Prescence of a Y chromosome is better. Though in a perfect world it would be determined entirely on physical ability with people going into whatever tier they are physically in, irrespective of anything else.

But that is trickier than just going by chromosome.

Yes Datun, that's how I feel. Also, it must have been very obvious to everyone involved in Semenya's career that they had gone through male puberty when they shaved 7 seconds off their previous time. That just doesn't happen to women.

Great post, Fuzzy.

You are far nicer than I am, Datun. I just feel duped. I feel like my support back in the day was deliberately coerced. As a female 800m runner (nowhere near as fast as CS, but competitive on the county circuit) I was chuffed to have a strong female role model. I like my women to eschew stereotypes . What really smarts is that it turns out the naysayers were right all along, thus enabling more racist misogynistic targeting of black women, not just in sport, but elsewhere.

A mistake was made, no one should have tried to hide it. They have continued to hide the mistake resulting in more XY DSD people entering XX competitions.

The existence of XX competitions is due to the advantage conferred by male puberty and testosterone on XY people.

Perfect.

Paper which discusses the clear difference in testosterone levels between males and females, including where disorders place people outside the normal ranges.

Even the most extreme outliers with marked PCOS (5.5nmol) do not come close to the levels of testosterone shown by CS who has been told to reduce levels to 5nmol and previously to 10nmol so the actual naturally occurring levels are above 10nmol.

For clarification, the normal range for healthy women extends to 2nmol.
