Fact check: How do sports organizations verify athlete gender eligibility?

Checked on June 16, 2025

1. Summary of the results

Gender eligibility verification in sports has evolved significantly over time. Currently, the International Olympic Committee (IOC) has established a Framework that provides principles rather than universal regulations, allowing individual sports organizations to develop their own criteria [1]. The primary method used today is testosterone level testing, with most organizations setting thresholds around 5 nanomoles per liter for female athletes [2].

2. Missing context/alternative viewpoints

The original question overlooks several crucial historical and ethical aspects:

  • Historical Evolution: Gender verification has progressed from highly invasive physical examinations in the 1960s to more scientific approaches [3]. By the 1990s, earlier invasive methods were abandoned due to ethical concerns [4].
  • Current Framework Complexity: The IOC's approach now encompasses 10 principles, including:
    • Creating safe environments for all athletes
    • Maintaining fair competition
    • Preventing discrimination
    • Sport-specific competitive advantage assessment
    • Stakeholder consultation [1]

  • Ongoing Scientific Debate: There is continuing discussion in the scientific community about how to fairly determine athletic eligibility across different sex and gender variations [4].
  • 3. Potential misinformation/bias in the original statement

    The question implies a straightforward, universal process, which misrepresents the current reality:

    • Diverse Approaches: Different sports governing bodies maintain their own specific regulations [2], rather than following a single standardized process.
    • Stakeholder Interests:
      • Sports organizations benefit from clear, defensible criteria
      • Athletes' rights advocates benefit from more inclusive policies
      • The IOC has shifted responsibility to individual sports bodies while emphasizing ethical, social, cultural, and legal considerations [1]

    The verification process is far more complex than simple testing, requiring a balance between fair competition, human rights, and scientific evidence [1].
