Transgender Women Could Be Banned from Female Olympic Events After New IOC Review
The International Olympic Committee (IOC) is reportedly preparing to ban transgender women and athletes with differences in sex development (DSD) from all female Olympic events starting next year.
The potential policy shift follows growing scientific and public debate over fairness in women’s sports and the eligibility of transgender and intersex athletes.
According to The Times, IOC members were recently shown research highlighting biological advantages retained by athletes assigned male at birth, even after undergoing testosterone suppression therapy.
The IOC launched a comprehensive scientific review last year after the Paris 2024 Olympic Games became mired in controversy surrounding boxing gold medalist Imane Khelif of Algeria and Chinese Taipei’s Lin Yu-ting.
Both athletes faced scrutiny and accusations regarding their eligibility to compete in women’s categories, sparking widespread debate about fairness and inclusion in elite sports.
Dr. Jane Thornton, the IOC’s medical and scientific director and a former Olympic rower for Canada, presented findings that reportedly influenced the organization’s latest position.
The data, according to insiders, indicates that certain physiological traits associated with male puberty—such as bone density, muscle mass, and cardiovascular capacity—can persist despite hormonal treatment, providing ongoing competitive advantages.
Until now, the IOC allowed transgender women to compete if their testosterone levels were kept below a certain threshold as approved by individual sporting federations.
However, the new stance could establish a universal ban across all female Olympic categories, removing the responsibility from federations and setting a global precedent for inclusion policies in sport.
New IOC president Kirsty Coventry, a former Olympic swimmer from Zimbabwe, has taken a strong position on protecting the integrity of female categories.
Since assuming office in June, Coventry has assembled a task force of scientists and international sports federations to reassess eligibility rules, aiming to strike a balance between fairness and inclusion.
Coventry confirmed that the IOC’s focus is on ensuring fair competition for biological women, particularly after mounting pressure from female athletes and sporting bodies.
“There was overwhelming support that we should protect the female category,” Coventry said earlier this year. “We are the ones who should bring together the experts and federations to ensure that we find consensus.”
She emphasized that while the IOC respects gender diversity, the primary responsibility of the Olympic movement is to maintain a level playing field. “It was fully agreed by members that, as the IOC, we must make the effort to emphasize protection of the female category,” she stated.
The new policy is expected to take effect ahead of the 2026 Winter Olympics in Milan-Cortina, marking a significant change in Olympic governance and athlete eligibility.
The possible ban has already drawn mixed reactions from the sporting community. Advocates for inclusion argue that such policies risk discriminating against transgender and intersex athletes, while others insist that biological differences cannot be ignored in competitive sports.
The controversy echoes past cases, including that of New Zealand weightlifter Laurel Hubbard, who made history at the Tokyo 2020 Olympics as the first openly transgender athlete to compete.
Although Hubbard did not win a medal, her participation reignited discussions over fairness, inclusion, and athlete safety.
Meanwhile, athletes with DSD—such as Imane Khelif, who maintains that she was born and raised as a woman—have faced intense public scrutiny. DSD conditions involve atypical development of chromosomal, gonadal, or anatomical sex characteristics, leading to complex classification challenges in sports.
World Athletics, under the leadership of Sebastian Coe, has already taken a hardline stance, banning transgender women who have experienced male puberty from competing in female categories.
If the IOC adopts a similar position, it would align Olympic competition with existing policies in athletics and swimming.
Despite the potential for sweeping reform, Coventry has clarified that the IOC will not apply the new rules retroactively. Past results, including those from Tokyo and Paris, will remain unchanged.
“We are not going to be doing anything retrospectively,” Coventry confirmed. “We are going to be looking forward — learning from the past and moving that forward into the future.”
The IOC has yet to release an official statement confirming the ban, stating only that the working group’s discussions are ongoing. However, with growing pressure from athletes, federations, and member nations, the final decision is expected before the start of the Milan-Cortina 2026 Games.
As the world’s most prestigious sporting body, the IOC faces an increasingly delicate balancing act between inclusivity and competitive integrity. The forthcoming decision could reshape the future of women’s sport — not only at the Olympics but across global athletics.
For now, the IOC’s evolving stance signals that the era of testosterone-based eligibility criteria may be coming to an end, as sports governing bodies move toward clearer, science-based definitions of fairness and equality in female competition.
