Transgender swimmer Ana Caldas banned by World Aquatics, stripped of recent results after refusing sex test
World Aquatics has issued a five-year ban on transgender swimmer Ana Caldas and nullified her results from June 2022–October 2024 after she refused a requested sex-verification test, reviving global debate over eligibility, privacy and enforcement in women’s sport.
- Sanction: Five-year ban through October 2030 and annulment of results from June 2022 to October 2024.
- Reason: Caldas declined a requested chromosomal/sex-verification test and was found to have breached integrity and gender-eligibility rules.
- Trigger: Complaints followed her wins at a U.S. Masters meet in San Antonio, prompting investigation.
- Contested issues: The case highlights tensions between fair-play policies, athlete privacy and how local meets align with international rules.
Background and how the case unfolded
The ban followed complaints after Caldas won five gold medals at a U.S. Masters Swimming meet in San Antonio, Texas, in May 2024, racing in the women’s 45–49 age group, according to AOL News and Fox News. The Independent Council on Women’s Sports (ICONS) filed an official complaint alleging Caldas’ participation compromised fair play.
World Aquatics enforces a 2022 gender-eligibility framework that allows transgender women to compete in women’s events only if they transitioned before age 12 or before reaching Tanner Stage 2 of puberty. After complaints, the Aquatics Integrity Unit requested Caldas undergo a sex verification test (described publicly as a chromosomal analysis) to confirm eligibility under that policy, per reporting by the Star Observer and other outlets.
Why Caldas refused the test
Ana Caldas declined to submit to the requested gender verification. She described the exam as “invasive” and “costly”, saying it was not required by U.S. Masters Swimming or any U.S. state for recreational competition and that insurance would not cover a test deemed not medically necessary. Caldas framed her refusal as an effort to protect private medical information.
“But a five-year suspension is the price I have to pay to protect my most intimate medical information. I’m happy to pay that price – for myself and for all the women who don’t want to undergo invasive testing.”

World Aquatics’ rationale and penalties
World Aquatics and its Aquatics Integrity Unit cited violations of their integrity code and gender-eligibility rules, saying Caldas failed to comply with a direction to provide required information and that her participation breached rules designed to ensure fairness in female categories. The unit imposed a five-year competition ban through October 2030 and stripped Caldas of all competitive results between June 2022 and October 2024, erasing official placements and medals from that period, as reported by AOL News and Fox News.
Reactions from competitors and the public
Reactions were sharply divided. Some competitors said they felt cheated or uninformed about racing against a transgender athlete. Louisiana swimmer Wendy Enderle, who raced against Caldas, said she felt “betrayed” after learning of Caldas’ sex assigned at birth, according to media coverage.
At the same time, civil liberties and LGBTQ advocates criticized the requirement for chromosomal or other invasive tests, arguing such mandates can violate privacy and bodily autonomy. Caldas’ statement framed the dispute as a conflict between governing-body rules and medical privacy (Star Observer).
Broader context: policy, precedent and controversy
The Caldas case is part of an ongoing global debate about transgender women in sport and how to balance inclusion, fairness and privacy. World Aquatics’ 2022 policy is one of several stricter rules adopted by international bodies seeking clear eligibility criteria for female categories. High-profile prior disputes — such as the controversy involving college swimmer Lia Thomas — prompted legal and policy challenges and wide public debate (CBS News; ESPN).
Attempts to overturn World Aquatics’ eligibility rules have so far been unsuccessful in major legal forums, reinforcing federations’ authority to set competition standards while leaving unresolved questions about enforcement and medical privacy (Athlete Ally).
What this means for gender verification testing and transgender women in sport
The decision spotlights tensions over gender verification tests. Advocates for strict verification argue tests protect fairness in women’s sport by confirming eligibility under specific transition timelines. Opponents say such tests can be invasive, medically unnecessary and discriminatory, especially for recreational or masters-level athletes who typically race outside elite international pathways.
The Caldas ruling may prompt national and local organizers to reassess how they screen entrants: whether to align with World Aquatics’ rules or maintain less intrusive standards for community events. It also increases the likelihood of more complaints and investigations where strict eligibility criteria are in place.
Implications for the Inland Empire
Economic and sports programs
Local masters and recreational swim meets in the Inland Empire may face pressure to clarify eligibility. Clubs and community centers hosting meets might need to update entry forms and protocols, which could increase administrative burdens or prompt legal consultation. Swim businesses, coaches and meet organizers may see shifts in participation if transgender athletes avoid events with stricter checks.
Political and policy consequences
Local policymakers — including city recreation departments and county officials — may be asked to weigh in on community sports rules. Debates could include anti-discrimination policies, the limits of local authority over recreational programming, and how to balance inclusion with fairness concerns. School districts and public aquatics programs may review policies to align with state law and local values, especially given California’s protections for transgender students and athletes.
Social and community effects
The case may heighten tensions among parents, athletes and coaches. Conversations about privacy, safety and fairness could become more prominent at poolside meetings. Local LGBTQ groups might mobilize to protect athlete privacy, while other community groups could call for clearer eligibility rules — potentially generating forums, school board debates or new municipal guidance.
Practical applications for local organizers
- Review and update entry requirements, data-privacy practices and appeal procedures to avoid ad hoc responses to complaints.
- Create clear communication plans so competitors understand rules and what, if any, medical information will be required.
- Consider legal guidance on how state anti-discrimination laws intersect with sport-governing bodies’ eligibility rules.
- Provide training for coaches and volunteer officials on handling sensitive questions about gender identity while protecting privacy.
