Rojo, I've been a fan of how this site has covered the Semenya issue for some time but your latest article is a bit embarrassing. It's like you forgot everything we've learned over the last 5 years. Karyotype is NOT the sole predictor of phenotypic sex - if it was we wouldn't have this issue. It's easy to karyotype people. (I've said this 500 times on LRC by now) Ross Tucker said it best yesterday: "Why? Because being “male” is a natural genetic advantage! It may be the greatest of them all! If you have the Y chromosome, and the testes, and the testosterone, and you can use the testosterone, then you have a huge advantage compared to a woman who has all the same other attributes, but not those." and "A 46XY DSD is not necessarily biologically male – this, indeed, is a point of debate in this issue. They DO lie on a spectrum, and since I’m interested in performance, you can pin that performance advantage of having a condition causing a 46 XY DSD on a spectrum of 0% to say, 12% (the full male advantage). But at this point, knowing where to drop that pin is the problem." You REALLY should read his take if you haven't. It covers a lot of scientific issues that LRC seems to now willingly ignore. The chromosome issue is a moot point. There have been XY humans competing and living as women for a loooong time and no one cared. You need to produce the T and respond to the T to have masculine benefits. Here is Tucker's article again:https://sportsscientists.com/2019/05/on-dsds-the-theory-of-testosterone-performance-the-cas-ruling-on-caster-semenya/

She is not XX. She is XY. The reporting on this has been so bad by the linkes of the BBC, New York Times, Washington Post, etc that I have written a column clearing up 3 common misconceptions about Semenya.
