Why in news?

The International Olympic Committee (IOC) has introduced a new policy restricting participation in women’s events to “biological females,” effectively excluding transgender and some intersex athletes.

The decision, aimed at ensuring fairness and safety in competition, will take effect from the 2028 Olympics. It follows pressure from the U.S., including an executive order by President Donald Trump.

The move has intensified ongoing debates around inclusion, fairness, and eligibility in women’s sports, especially after controversies like the 2024 Olympics boxing case.

Understanding the Distinction Between Sex and Gender

• The IOC, after consulting experts across multiple fields, emphasised that eligibility for the women’s category should be based on biological sex, highlighting the need to clearly distinguish between “sex” and “gender”.
• What is Biological Sex?
  • Sex refers to biological differences such as reproductive organs and chromosomes.
  • Humans typically have XX chromosomes (female) or XY chromosomes (male), though variations exist.
  • Some individuals, such as those with Disorders of Sex Development (DSDs), may not fit neatly into this binary, as seen in cases like athlete Caster Semenya.
    • Intersex individuals possess physical or genetic traits that do not align strictly with typical binary definitions of male or female.
    • As an example of a DSD, individuals with Swyer syndrome may have female reproductive organs despite carrying XY (typically male) chromosomes.
    • The text cites the high-profile case of Olympic athlete Caster Semenya, who has a DSD.
    • Her situation has sparked legal battles over sports regulations that require athletes with high natural testosterone to medically suppress those levels to compete in women's categories.
• What is Gender?
• Gender is a social and personal identity — how individuals perceive themselves, such as male, female, or non-binary.
• It may not always align with biological sex. For instance, a transgender woman may be biologically male but identifies as female.
• Key Difference
  • While sex is biological, determined by physical and genetic traits, gender is psychological and social, based on identity.
  • This distinction lies at the heart of ongoing debates in sports eligibility policies.

Why Gender Eligibility is Controversial in Women’s Sports?

• The debate over gender eligibility in women’s sports stems from the fact that modern sports are divided based on biological sex, as men generally possess physiological advantages over women.
• Role of Testosterone in Athletic Performance
  • Testosterone, influenced by the SRY gene on the Y chromosome, is linked to greater muscle mass, strength, bone density, and haemoglobin levels.
  • Studies suggest this hormone largely explains performance differences between male and female athletes, with an estimated 10–20% advantage in certain sports.
  • While evidence supports testosterone’s impact, it is not fully conclusive.
  • Critics argue that natural variations, such as higher testosterone in some women or genetic advantages like height or limb structure, complicate the fairness argument.
• Core of the Debate
  • The central issue is whether athletes with higher natural testosterone levels—such as those with DSDs or transgender women—have an unfair advantage.
  • Some advocate restricting their participation to ensure fairness in women’s sports.
  • The IOC maintains that allowing transgender and certain DSD athletes in women’s categories may compromise fairness, safety, and competitive integrity, especially in sports dependent on strength, power, and endurance.

Global Shift in Sports Eligibility Rules

• The IOC’s new policy marks a significant departure from its 2021 approach, where international federations were allowed to frame their own rules based on fairness, inclusion, and scientific evidence.
• Now, the IOC has indicated that its stricter criteria should be widely adopted across global sports bodies, potentially standardising exclusionary rules.
• Existing and Emerging Regulations
  • Many international federations had already imposed restrictions based on testosterone levels.
  • For instance, World Athletics requires DSD athletes to maintain low testosterone levels, while sports bodies like FINA, cycling, and rugby have implemented varying bans on transgender women.
    • Some have also introduced genetic testing, such as the SRY gene test, to determine eligibility.
  • The issue has evolved into a broader conflict between fairness (ensuring a level playing field for biological women) and inclusion (allowing participation regardless of gender identity).
  • Critics argue that blanket bans may ignore differences across sports and individual cases.
• Challenges of Alternative Solutions
  • Proposals like creating an “open category” for transgender athletes face practical challenges due to the limited number of elite-level participants, making implementation difficult.
• Social and Political Implications
  • The policy is likely to deepen global debates around gender identity and sports.
  • Advocacy groups warn it could discourage participation at grassroots levels, making transgender individuals feel excluded, and further polarising discussions on gender and inclusion in society.
