International Olympic Committee: Only ‘biological women’ allowed to compete in women’s category
The International Olympic Committee (IOC) established a new policy restricting participation in the women's category to only "biological women." The policy, effective from the 2028 Los Angeles Olympic Games, excludes "biological men" who self-identify as women from competing in the women's category. IOC member Kirsty Coventry asserted the decision is based on scientific evidence showing performance advantages derived from male chromosomes in strength, power, or endurance sports. Eligibility testing will involve checking for the SRY gene via saliva or blood sample, with a negative result confirming eligibility for the female category for life, unless the result is believed to be erroneous. The IOC stated that allowing biological males to compete would be unfair and, in some sports, unsafe.

The International Olympic Committee (IOC) announced a new policy on March 26, 2026, restricting the women's category to biological women only, excluding biological males who self-identify as women.1 2 3
This policy takes effect for the 2028 Los Angeles Olympics and is not retroactive.1 2
IOC member Kirsty Coventry, a two-time Olympic swimming champion, emphasized the policy's basis in science, prioritizing fairness and safety in competition.1 2 3
She highlighted that male chromosomes confer advantages in strength, power, and endurance sports, where small margins decide outcomes.1 2
Athletes will undergo a one-time SRY gene test via saliva, cheek swab, or blood to detect male sexual development.1 2 3
Negative results grant permanent eligibility for the women's category, barring errors; positive results bar participation except in rare cases.1 2
Exceptions apply to athletes with Complete Androgen Insensitivity Syndrome (CAIS) or certain DSD conditions without testosterone benefits.1 2
Those testing positive, including XY transgender or androgen-sensitive XY-DSD athletes, may compete in male, mixed, or non-sex-classified events.1 2 3
The policy stems from a 2024-2026 IOC review, including a September 2025 working group of global experts in science, medicine, ethics, and law.1 2
Over 1,100 athlete surveys, interviews, and Athletes’ Commission discussions showed strong consensus on protecting the women's category.1 2
Guided by goals of equality, Olympic value, and inspiring female athletes, the policy aligns with some national federations' prior restrictions.1 2 3
It recentralizes rules amid fragmented approaches in sports like athletics and swimming.3
Scientific evidence is contested, with experts like Eric Vilain noting uncertainty on retained advantages post-testosterone suppression.3
Legal challenges, privacy issues in countries like France, and ethical concerns for young athletes (as young as 11) are anticipated.3
Assess Catholic doctrine on gender identity and athletic participation
Catholic teaching firmly roots human identity in the biological reality of sexual difference, as God created humanity "male and female" (Gen 1:27), with body and soul forming an inseparable unity. The Catechism of the Catholic Church states: "By creating the human being man and woman, God gives personal dignity equally to the one and the other. Each of them, man and woman, should acknowledge and accept his sexual identity." This sexual identity is not a social construct or personal choice but a gift inherent to the person's embodied nature, where the body "shares in the dignity of 'the image of God'" and manifests the soul's interiority.
The Church critiques "gender theory" or "gender ideology" as an ideological denial of this natural order. It "denies the difference and reciprocity in nature of a man and a woman and envisages a society without sexual differences, thereby eliminating the anthropological basis of the family." This ideology promotes "a personal identity and emotional intimacy radically separated from the biological difference between male and female," reducing identity to individual choice that can change over time. Popes Francis and Benedict XVI have warned of its roots in constructionist theories from the 1960s-1970s, which claim gender is independent of biological sex, justifying diverse sexual attitudes and redefining family. The Canadian Conference of Catholic Bishops echoes this, questioning whether denying sexual difference resolves relational issues or aligns with "the beauty of God’s creative design" evident in our bodies.
Recent magisterial teaching in Dignitas Infinita (2024) addresses sex-change interventions directly: "any sex-change intervention, as a rule, risks threatening the unique dignity the person has received from the moment of conception." Exceptions are limited to resolving genuine genital abnormalities (Disorders of Sex Development, or DSD), not ideological transitions. Gender dysphoria—distress from perceived incongruence between gender identity and biological sex—is distinguished from DSD or homosexuality; its etiology involves multifactorial biological, psychological, and social elements, but interventions mutilating the body are unethical. Scholarly analyses trace this ideology's logic to severing sex from gender, enabling "self-identification" or biotechnological reversal, contrary to the Church's anthropology.
The Catholic Church views sport as a path for integral human development, fostering the unity of body, soul, and spirit while promoting values like sacrifice, justice, loyalty, friendship, and solidarity. Documents from the Dicastery for Laity, Family and Life emphasize: "The Church understands the human person as a unit of body, soul and spirit, and seek[s] to avoid any kind of reductionism in sport that debases human dignity." Sport educates the whole person, echoing St. John Bosco's oratories and papal traditions from Leo XIII to John Paul II, where it serves fraternity, peace, and evangelization.
Pope Leo XIV's 2026 Letter on the Winter Olympics warns against modern distortions: "Contemporary challenges are intensified by the impact of transhumanism and artificial intelligence on the world of sport. Technologies applied to performance risk introducing an artificial separation between body and mind, transforming the athlete into an optimized, controlled product, enhanced beyond natural limits." When technology "claims to redefine [the person], sport loses its human and symbolic dimension." Sport must remain incarnational, relational, and educational, not a "laboratory for disembodied experimentation." Challenges like "debasement of the body" (e.g., doping) demand the Church's guidance to humanize sport.
Applying these doctrines, Catholic teaching implies that athletic participation must respect biological sexual identity to preserve human dignity and sport's integrity. Gender ideology's separation of "gender" from sex parallels the transhumanist risks Leo XIV critiques: both artificially redefine the body, undermining the "sexed condition" that endows personal meaning and relational capacity. Allowing biological males identifying as female (or vice versa) to compete in the opposite sex's category risks debasing the body, creating unfairness, and eroding sexual complementarity essential to anthropology.
Sport's purpose—integral growth and fair competition—requires categories based on biological sex, as the body is not malleable for ideological ends. Transition-related interventions threaten dignity by rejecting creation's order, akin to biotechnological enhancements that "disconnect sport from individuals and concrete relationships." While pastoral accompaniment is urged for those experiencing dysphoria—listening to cries for identity, freedom, and belonging—the response is Christocentric, not affirmational of self-identification. Nihilism and lack of meaning fuel transgender identification; sport, as a "school of humanity," should counter this by affirming embodied reality.
No source explicitly mandates policies, but principles prioritize: (1) biological sex for fair, dignifying competition; (2) inclusion via non-competitive or adaptive categories; (3) accompaniment addressing root wounds without endorsing mutilation. Dignitas Infinita's recency and magisterial authority reinforce this over earlier scholarly works.
In summary, Catholic doctrine rejects gender ideology's fluid identity, affirming fixed biological sex as dignity's foundation. Sport humanizes when honoring body-soul unity; transgender participation contravening biology risks ideological colonization, echoing transhumanism's dangers. The Church calls for compassionate truth, protecting creation's design amid cultural pressures.
