In that interview she makes this statement
"We see that 1/6 of elite male track and field athletes have lower than the average female testosterone yet they perform at a higher level, so it’s not just about testosterone"
Does anyone have a source for that claim?
I found this published
"There are very limited published data on endocrine profiles in sport, most being confined to a single sport. One unexpected finding of Healy et al.  was that 16.5% of male elite athletes had testosterone concentrations less than the lower limit of the laboratory reference range for ‘normal’ men" https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5804043/
Note men not women
So is she arguing that there should be no sex categories in sports like track and field? This is actually not unreasonable and would sort out the Semenya situation (I would however draw the line at combat sports). Or is she arguing that there should be testosterone categories in sports?
