Transgender Athlete Policy Has Become a Political Weapon. Sport Is the Casualty.

In March 2023, World Athletics announced a policy barring transgender women who had experienced male puberty from competing in female track and field events at international level. The decision was framed by president Sebastian Coe as one about "protecting the female category" and was explicitly divergent from the IOC's 2021 framework, which had moved away from testosterone-threshold-based exclusion toward a more case-by-case approach managed by individual sports federations. The two most powerful bodies in international sport had produced incompatible governance frameworks on the same question, and neither showed any urgency about resolving the contradiction.

What followed was not a science debate, despite the volume of scientific language deployed by all parties. It was a political cascade. National federations scrambled to align with one framework or the other. Swimming's World Aquatics adopted an even more restrictive policy than World Athletics. Cycling's UCI introduced testosterone thresholds. Rugby's World Rugby had pre-empted the conversation in 2020 with a blanket ban at international level. A patchwork of incompatible policies across sixty-plus Olympic disciplines now governs the competitive eligibility of a small number of athletes whose individual circumstances vary considerably but who are collectively made to carry the symbolic weight of a much larger culture-war.

The point is not that competitive fairness is irrelevant. It is that the specific policy incoherence — different rules in different sports, different threshold numbers, different transition timelines, different categories of documentation required — is not explained by the scientific evidence, which does not support such fine-grained distinctions. It is explained by the political environments in which governing bodies operate.

The Science That Is Actually Available

The scientific literature on transgender athlete performance is considerably smaller and more uncertain than the public debate implies. The most cited studies — conducted by researchers including Emma N. Hilton, Tommy Kreher and Joanna Harper — examine physiological parameters like VO2 max, muscle mass retention and haemoglobin levels in transgender women following hormone therapy. The findings are genuinely mixed: some parameters converge toward typical female ranges within two to four years of hormone therapy; others, including height, hand-span and lung capacity, do not fully converge on typical ranges regardless of transition timeline.

What the literature almost entirely lacks is competitive performance data for transgender athletes at elite level — because the number of openly transgender women competing at elite international level in any single discipline is very small, in most sports numbering in the low single digits globally. Policy is being made on the basis of physiological inference, not observed competitive outcomes.

Anouk Aubert's work on sport and gender governance notes that this evidence gap creates a condition she describes as "precautionary exclusion": governing bodies invoke the possibility of performance advantage to justify exclusion in the absence of evidence that such advantage is actually being realised at the competitive level. The precautionary logic sounds scientifically conservative but operates as a default ban — because in conditions of uncertainty, exclusion is always available as a "safe" option, while inclusion requires affirmative justification.

Sebastian Coe and the Constituency Problem

Sebastian Coe's World Athletics operates with a particular political constraint: a significant portion of its member federations are from countries — in sub-Saharan Africa, the Gulf, South and Southeast Asia — where transgender identity is either criminalised, socially marginalised or both, and where the political cost of a permissive eligibility policy would translate into domestic political difficulty for national athletic leadership. Coe is an elected president of a voluntary federation, which means he is managing a coalition as much as he is making sport policy.

This is not to suggest that Coe's scientific concerns are entirely pretextual — his public statements have been more nuanced than the policy's critics sometimes acknowledge, and his specific concern about post-pubertal advantage in strength-dominant disciplines is not without grounding. But it is to note that the World Athletics policy lands with a convenience that serves the federation's internal political management. A restrictive policy insulates Coe from pressure from socially conservative member federations while placing the burden of challenge on individual athletes and their national bodies, who face considerably higher costs for contesting the policy than World Athletics faces for enforcing it.

The IOC's Deliberate Ambiguity

The IOC's 2021 framework — which explicitly stated that no athlete should be presumed to have an advantage solely on the basis of gender identity, and delegated eligibility decisions to individual sports federations — was not a principled commitment to inclusion. It was a principled commitment to avoiding responsibility. By pushing the decision to federations, the IOC preserved its ability to endorse whatever outcomes emerged without having been accountable for any of them.

This is consistent with the IOC's approach to a range of contested governance questions: provide a framework document that can be cited as progressive, delegate actual decision-making to bodies over which the IOC has limited practical authority, and respond to controversy by affirming the framework without intervening in its application.

The consequence for athletes is a landscape in which eligibility is sport-specific, jurisdiction-specific and — in practice — often federation-official-specific. A transgender athlete who is eligible to compete in cycling may be ineligible in athletics; eligible at national level in one country but ineligible at international level under World Athletics rules; eligible this year under a given threshold and potentially ineligible next year if the threshold is revised. This is not a coherent governance system. It is a series of political accommodations wearing a policy framework's clothes.

What Athletes Actually Experience

The athletes at the centre of this debate are, almost uniformly, not consulted in any meaningful way about the policies that govern their competitive lives. Caster Semenya's decade-long legal battle against World Athletics' testosterone regulations — which the European Court of Human Rights ultimately found in 2023 violated her right to a fair trial and freedom from discrimination — illustrated what the regulatory process looks like from the athlete's position: years of invasive testing requirements, public speculation about her body and biology, competitive exclusion from her primary event, and an eventual ECHR ruling that produced no immediate policy change.

Dave Zirin has consistently noted that the athletes most affected by these policies — transgender women, intersex women, athletes with differences of sexual development — are among the least resourced to contest them, while the political actors most energised by the debate (American Republican legislators, British culture-war commentators, conservative sports officials) bear none of the competitive or personal costs involved.

The result is a policy environment in which the formal vocabulary is always about fairness and science, and the practical operation is about which bodies get to be comfortable in a changing room, on a starting line, in an interview room where a journalist will ask about their hormones. That is a question about dignity and power, which are exactly the terms that the governing bodies' scientific framing is designed to avoid.
