> Using 1-sigma in your example is a straw man. Normal female range is 15 to 70 ng/dL, normal male range is 300-1200
My error; I was speaking from pure hypotheticals without knowledge of how the numbers break down. The regulations from IAAF (and the research from the IAAF) indicates "About seven in every 1,000 elite female athletes have high testosterone levels." (https://www.sciencedaily.com/releases/2019/02/190212160030.h...)
Still, their stance seems odd... That a person with naturally-occurring testosterone should be required to take suppressing hormones. If the goal is to see "natural" talent apart from doping, how does forcing athletes to take hormone suppressants satisfy that goal? It seems to pretty self-evidently be reverse-doping.
It's also unclear to me why the IAAF would consider higher levels of testosterone to be an advantage in need of intervention but not, say, being born at and training in a higher altitude, which we know increases lung capacity https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4175264/. We don't force athletes training in Santa Fe to train at lower altitudes for six months before an Olympics. Why treat testosterone levels differently?
It suggests that the issue is something else, not what was raised. It reads as an accusation that the hormone issue is just an excuse for an other agenda. If that wasn't your intention I belive you, but it can be easily misread.

I think the goal is both finding what humans are capable of, but also rewarding human achievement. If a world record can only be broken or a race can only be won by someone in the top 0.1% of testosterone levels then 99% of people have no reason to even try to compete.
Training at a high altitude is still within the reach of natural human ability, while taking hormones isn't. Although I would support the idea that everyone can take as much testosterone as you need to get to 1200 ng/ml (or some other reasonable threshold) but not more.
