Epstein: On Twitter, a lot of people were sharing a picture of Michael Phelps’ arms, with people saying, “He’s got long arms, and that’s natural. So why would we regulate Caster Semenya for high levels of testosterone?” Well, on the Paula Radcliffe side, the problem with that argument is that we don’t divide sports by arm length. We do divide it by sex. If you’re going to have a female classification, it has to mean something. The reason we have the female classification is because there’s tremendous value in having women’s sports. If we only had one competitive classification for all comers, then the best women wouldn’t be able to compete with the best man. The question is, how do you define who is allowed entry into that female classification? Again, we don’t divide sports by arm length or height. But testosterone is not height. A man in the low level of the typical male testosterone range still has testosterone several hundred percent higher than a woman at the top of the typical female range. I think the Paula Radcliffe side is saying, We need the women’s classification to mean something. Testosterone is a reasonable surrogate marker for differences of biological sex.
