We must keep female sports for women and girls only
Ensuring equal opportunity and fairness is the cornerstone of all sport.
However, local, national, and international policies increasingly allow males who identify as female to compete in sports reserved for women and girls. The whole reason sex-based sports categories exist is to ensure fair competition by accounting for physiological differences, therefore enabling sports to reward genuine merit and excellence.
And yet, gender ideology is playing a significant role in the attempt to erode this biological foundation by claiming that gender identity—how one personally experiences one’s gender—may not necessarily align with one’s biological sex.
This radical ideology argues that each person should be permitted to compete on a sports team that aligns with their gender identity rather than biological sex, contributing to egregious violations of the rights of female athletes when males are allowed to invade their sports and spaces.
Gender Ideology’s Role in Undermining Women and Girls’ Sports
When laws and policies lose touch with the biological reality that men and women are inherently different, it’s women and girls who suffer the most.
Every woman and girl, from aspiring young athletes to seasoned professionals, deserves fair and safe access to spaces dedicated to female athletes. The future of women’s sports—and the opportunity for every girl to dream and compete—depends on this vital commitment to fairness.
A recent story out of San Jose State University in California illustrates the growing concerns around fairness in women’s sports. The university’s women’s volleyball team added a male player to its roster, prompting several other teams to cancel their matches against SJSU. While no official reasons for these forfeits have been given, the implications are clear.
A Matter of Fairness
Dr. Gregory Brown, an exercise science professor, has extensively explored the topic of male advantages in sports. In a white paper, he highlights that male athletes generally have a jumping advantage of approximately 15-20 percent over female athletes. Additionally, males spike the ball with greater speed, giving them a 29-34 percent edge in this area. Moreover, men generally possess greater height and muscle mass, providing clear benefits on the volleyball court.
It’s abundantly clear why female volleyball players wouldn’t want to compete against male athletes.
According to a recent UN report from August 2024, no less than 600 female athletes in 29 different sports have lost in competitions to male competitors. And we know the issue is not simply about medals. It’s about the countless opportunities, including academic and professional, a female athlete forfeits when a male displaces her. It’s also about basic safety, both on and off the playing field.
When female-only spaces such as locker rooms and restrooms are open to males, the privacy, safety, and security of women are compromised at the most basic level.
As debates over fairness and safety in women’s sports intensify, legal and policy frameworks worldwide are being scrutinised more closely. And the demand for clear, principled policies safeguarding female athletes is growing urgent. Thankfully, a bold response is emerging on the international stage.
Calling on Leaders to Ensure Fairness in Girls’ and Women’s Sports
ADF International, alongside our colleagues at Alliance Defending Freedom in the United States, is advocating for the rights of female athletes, standing up for the truth that female sports must be female-only if they are to be safe and fair.
In October, ADF International convened a panel to bring this critical conversation to the UN. Addressing government leaders and UN officials, the event brought together prominent advocates for protecting women and girls’ sports. Among the speakers were former West Virginia State University athlete Lainey Armistead, British Olympian swimmer Sharron Davies, CEO and President of Alliance Defending Freedom Kristen Waggoner, and the UN Special Rapporteur on violence against women and girls Reem Alsalem.
Armistead joined a lawsuit to defend a law in West Virginia ensuring that only women compete on women’s sports teams. That lawsuit has passed through the court system, and Alliance Defending Freedom asked the U.S. Supreme Court to hear the case. Joining Waggoner at the UN, Armistead said: “I’m here today because we’ve all seen what happens when males are allowed to compete on women’s teams.
From track to boxing to swimming, it’s demoralising and unfair—and just plain wrong.” Armistead recounted stories of women being sidelined and even injured in these situations. She highlighted that just one male athlete had already displaced nearly 300 female athletes in West Virginia.
Davies underscored that the biological differences between men and women put female athletes at a distinct disadvantage, stressing the need for safety measures in women’s sports. Waggoner, alongside the athletes, affirmed that equality and non-discrimination—especially regarding sex—are core principles of international human rights law. “When female sports aren’t protected,” Waggoner warned, “it does grave harm to women and girls.”
Waggoner concluded with a plea: “Our hope at ADF is that the international community will turn its attention to this critical issue—ensuring women and girls can pursue sporting opportunities should they desire, and protecting female athletes… Our plea to the world is to learn from the mistakes that have been made and that are now being corrected, so that your daughters, so that my daughter, can walk into a future of fairness and safety in sport.”
The International Implications
In 2021, the International Olympic Committee (IOC) revised its guidelines on transgender athletes, aiming to adopt a “more inclusive” approach to sports. However, this shift inevitably raised serious concerns about fairness and safety for female athletes.
In response, several international and national sports federations—including the World Aquatics, World Athletics, World Rugby, and the International Cycling Union—have decided to protect female-only categories. These organisations affirm that biological and physical differences remain relevant to fair competition in sports, so they’ve reinforced these categories to protect competitive balance and safety.
What the Universal Declaration of Human Rights Says
Article 1 of the Universal Declaration of Human Rights asserts that “all human beings are born free and equal in dignity and rights.” Article 3 of the Declaration on the Elimination of Violence against Women affirms that women are entitled to fully enjoy and be protected in all human rights and fundamental freedoms—whether in political, economic, social, or civil spheres. This includes specific rights such as freedom from discrimination, access to the highest attainable standards of physical and mental health, and protection from torture or any cruel, inhumane, or degrading treatment.
While the Universal Declaration does not directly mention sports, activities related to sports are widely recognised as part of the broader rights to education and cultural participation, as outlined in Articles 26 and 27. These rights affirm that everyone should be able to engage in sports and cultural activities that foster personal growth, community, and equality.
How We Can Ensure Girls’ and Women’s Sports Remains Fair
Establishing female categories has never been about division; rather, it’s about empowering women and girls and creating a fair playing field.
By raising this issue on an international stage, we’re bringing crucial attention to the challenges women and girls face as their sporting opportunities are impacted by the inclusion of males in female sports.
Conclusion: Laws Must Reflect Basic Fairness
We aim to uphold laws that recognise the fundamental biological differences between men and women. Through global alliances and strategic advocacy at both national and international levels, we believe meaningful change is within reach.
At its core, this issue is about protecting the dignity and respect female athletes deserve. We must ensure that the future of women’s sports remains a fair arena where women can compete without facing disadvantages from biological disparities or gender ideology. Protecting these principles is essential to preserving the integrity of female sports for generations to come.
This is a matter of basic human rights, and we must reaffirm, without hesitation, the imperative of safety and fairness in sports for women and girls.
