Last month, the Court of Arbitration for Sport (CAS) released a verdict that has become one of the most hotly debated rulings in sport history. At the centre of this decision is one woman: the South African mid-distance phenom Caster Semenya. Semenya has a condition called 46XY DSD, which results in her body producing higher than average levels of testosterone. The science and emotions behind this case are complex, and have divided the world of athletics in a way that is unprecedented.

In this episode, 3 guests offer their unique perspectives on this complex topic. Amby Burfoot is the former Editor-in-Chief at Runner’s World Magazine. In Part 1, we chatted with Burfoot about his reasons for agreeing with testosterone limits.

Today in Part 2, we talk with former track and field Olympian and professor Dr. Bruce Kidd. We also speak with Dr. Payoshni Mitra, who was instrumental in overturning the hyperandrogenism ruling in the 2015 Dutee Chand case. Dr. Kidd and Dr. Mitra share their reasons for disagreeing with the CAS ruling, and their hopes for the future. (To skip ahead to Part 2, go to 33:05)

    I’m not usually one to comment on words that are no longer politically correct as usually they come from an older person where they aren’t intentionally being offensive, but I was shocked to hear someone under the age of thirty use the phrase ‘he took some scalps’ in the most recent edition of the Shakeout podcast. In today’s Canada of indigenous reconciliation that is not a phrase needed to describe a runner. That’s not the kind of community I expect from runners or a podcost endorsed by Canadian Running.

  • Elsa says:

    Very dishonest to consistently present Semenya and Chand under the same category.
    Also unfortunate you use “T” instead of testosterone. Let’s use the proper words.
    Furthermore disingenuous, “hyperandrogenism” is NOT another word for intersex. It is a specific condition of females (no Y chromosome or testes) with elevated testosterone.
    The new IAAF regulations would have had zero impact on Chand, because the new regulations only apply to persons with a Y chromosome, thereby with testes. 46XY DSD persons have NORMAL male testosterone levels, with reduced testosterone processing capacity.
    THE BEST guideline for determining SEX is biological SEX, Y chromosome/testes. Everything else beyond that is splitting hairs.
    46XY DSD athletes outperform females (XX) by 6 to 1. 46SY DSD athletes were also the focus of the doping programmes in the Eastern Block, because coaches knew full well the competitive advantage for persons with LONG TERM high testosterone levels. So when some speakers claim it is a “brand new” discussion, that is false. we’ve known this for half a century. The only difference today is we’re more concerned with political correctness, rather than long known facts.
    Let’s redo this conversation with actual facts.

  • Elsa says:

    If female athletes were aware that the 46XY DSD practically prohibited XX athletes from medalling, there would be generalised outrage. Sadly, the facts are constantly being hidden, and women are duped. Same old Same old.

  • Elsa says:

    Bruce is wrong about convergence. This convergence was a thing way back when females were starting at elite sport. In the past decade or two, the convergence has mostly ceased. The difference of 10-12% in sporting performance is a complete correlation to the 10-15% difference in male and female body (sex not “gender”) sexual dimorphism.
    Bruce is further misrepresenting the “fear” factor. Females (XX) are NEVER a threat to the male elite athletes. This is not an issue. However, females (XX) are directly affected by XYs in their sporting field at all levels, regionals, state, national, because it’s NOT just about podium positions, but about qualifying opportunities, funding opportunities, scholarship opportunities.
    ALL athletes wishing to compete in the FEMALE category should undergo mandatory genetic testing. No exceptions.
    Furthermore, intersex conditions are not “more common” in the “Global South”. The difference is in proper medical expertise at time of birth, where sex verification at birth is erroneous. DSD athletes in Western countries suffered from this failure of medicine to properly assess sex. This situation has mostly been fixed in the West, and we can provide better sex assessment support in poorer countries.

  • Elsa says:

    Semenya just won with 2000m, while still specialising at the 800m, further demonstrating the entirely different category Semenya is competing in.

  • Elsa says:

    Not recognising biological sex (as opposed to superficial perceived “gender”) is discriminatory to females.
    Let’s get rid of testosterone testing entirely. Let’s bring back chromosome testing alone. That is all that matters.
