Sports Eligibility and Testosterone Testing: What Athletes Need to Know in 2026
Category eligibility, prohibited medication use and medical hormone evaluation answer different questions. Start by knowing which rules apply to you.

The short answer
There is no single universal “testosterone test for athletes.” Category eligibility depends on the sport, governing body and event. Anti-doping rules govern prohibited substances and methods. Clinical testosterone testing evaluates a medical question.
A prescription, a laboratory result within a reference interval or an eligibility screen does not automatically satisfy the other requirements.
Three different questions
1. Eligibility
Can I compete in this category?
The governing body applies its eligibility policy. This may involve records, genetic screening and further assessment under its rules.
2. Anti-doping
Is my medication permitted?
The applicable prohibited list and exemption process determine whether treatment is allowed in sport.
3. Medical testing
Do I have a hormone issue?
A clinician interprets symptoms, history and laboratory results to guide diagnosis and care.
Olympic eligibility policy changed in 2026
The IOC announced its new female-category policy on March 26, 2026. Its application begins with LA28 and subsequent IOC events; it is not retroactive and does not govern grassroots or recreational sport.
The New Zealand Olympic Committee’s policy explanation describes one-time SRY-gene screening rather than a universal blood-testosterone threshold. The policy includes defined exceptions, including complete androgen insensitivity syndrome in the specified circumstances, and procedures for further assessment. Athletes should obtain the complete requirements through their federation or Olympic committee.
Announcement date and effective date are different. Do not assume that every competition held in 2026 follows the LA28 policy.
World Athletics uses SRY testing
World Athletics introduced SRY screening for female-category eligibility under rules effective September 1, 2025. The sample can be a cheek swab or blood sample. Its rulebook and event instructions govern implementation and any additional assessment.
SRY means sex-determining region Y. Screening looks for genetic material; a routine testosterone test measures circulating hormone. Taking blood for either test does not make them the same test.
A screening result should be handled through the official confidential process. It is not a complete medical diagnosis or a reason to speculate about an athlete’s health or identity.
Different sports can have different rules
World Athletics rules should not be substituted for IOC, college or boxing rules. Check the organization, event, age category and effective date.
- World Boxing: its sex-eligibility rulebook amendment requires athletes aged 18 and over at its owned or sanctioned competitions to complete a once-in-a-lifetime PCR or approved equivalent genetic test before competition. Certification and assessment follow its policy.
- NCAA: its participation policy governs college category eligibility separately from medication exceptions. Under that policy, athletes assigned male at birth cannot compete on women’s teams; athletes assigned female at birth who begin testosterone therapy also cannot compete on women’s teams. Men’s-team participation remains subject to all other eligibility requirements.
Permission from one organization does not establish permission at a different event.
Eligibility testing is not anti-doping testing
An eligibility screen addresses a competition category. Anti-doping assessment addresses prohibited substances or methods. A routine hormone panel is not a substitute for a sporting authority’s anti-doping testing and review.
The 2026 WADA Prohibited List includes testosterone among anabolic agents prohibited at all times, in and out of competition. A normal clinical testosterone result does not demonstrate that testosterone use is permitted under those rules.
Prescription testosterone and therapeutic use exemptions
A medically justified prescription does not automatically authorize testosterone use in sport. Under WADA-based rules, athletes may need an approved therapeutic use exemption (TUE) from the appropriate anti-doping organization.
A TUE requires supporting medical evidence and satisfaction of defined criteria, including treatment need and the absence of a reasonable permitted alternative. It is not guaranteed by a low laboratory value or a clinician’s recommendation.
Ask the responsible organization about application timing, recognition at your event and renewal. Retroactive applications are limited to specified circumstances. An approved TUE addresses prohibited treatment; it does not override category-eligibility rules.
Clinical testosterone testing is different again
Clinical evaluation begins with symptoms, medical history, medication use and the reason for testing. In men being evaluated for hypogonadism, the Endocrine Society guideline emphasizes compatible symptoms and consistently low testosterone, confirmed with repeat morning testing.
Results need context: sampling time, assay, units, illness and medications can affect interpretation. Additional tests depend on the clinical question. A laboratory reference interval is neither a sports eligibility threshold nor permission to use TRT in competition.
Learn more about medical testosterone testing and understanding testosterone results.
What should an athlete taking TRT do?
- Identify the governing authority. Ask which eligibility and anti-doping rules apply to your event.
- Check treatment status. Review every prescription and supplement with the appropriate sports-medicine or anti-doping team.
- Tell your treating physician that you compete. Bring the organization’s documentation requirements.
- Complete the correct process. Obtain the required TUE or medical exception and confirm its scope before relying on it.
- Keep decisions current. Check expiry dates and report treatment changes as required.
Do not change prescribed treatment to chase an internet threshold or attempt to avoid a test. Coordinate medical decisions with your clinician and the responsible sporting authority.
Why a testosterone number alone does not answer the question
The same laboratory result can be relevant to clinical care without deciding sporting eligibility. Genetic screening, treatment authorization and clinical diagnosis rely on different information.
Likewise, appearance, strength or competition results are not evidence of someone’s chromosome findings, diagnosis or doping status. Sensitive health information deserves privacy and appropriate professional interpretation.

Coverage from Paris 2024 reflects the organizations and policies involved at that time. It cannot establish the rules for a later competition. This article now focuses on current source documents and practical distinctions rather than individual athletes or retrospective speculation.
Frequently asked questions
Can NCAA athletes take testosterone?
Testosterone requires the NCAA medical-exception process. Anabolic agents require pre-approval before practice or competition while using them. Work through the school’s sports-medicine and compliance staff. Category eligibility is a separate requirement. See NCAA medical exceptions.
Is prescription TRT banned in sports?
Under WADA-based rules, testosterone is prohibited at all times unless the applicable exemption requirements are met. A prescription alone is insufficient. Other organizations have their own processes.
What is an SRY test?
It is a genetic screen for the sex-determining region Y gene. Certain sports policies use it as part of category-eligibility assessment, with their own follow-up procedures.
Is SRY testing the same as a testosterone blood test?
No. SRY screening examines genetic material; a testosterone blood test measures a hormone concentration. Both may use blood, but they answer different questions.
Do all sports use the same eligibility rules?
No. Confirm the rules for the specific governing body, competition and date. An IOC policy does not automatically determine every federation’s or college program’s requirements.
What is a TUE?
A therapeutic use exemption is authorization through the applicable anti-doping process to use specified prohibited treatment for a documented medical need. It has conditions and a validity period; it does not grant category eligibility.
Clinical hormone evaluation at NovaGenix
Dr. Timothy Mackey is Medical Director of NovaGenix in Jupiter, serving patients in Palm Beach County. A consultation can address symptoms, appropriate testing and whether treatment is medically indicated.
NovaGenix provides clinical evaluation. Governing bodies decide sporting eligibility and medication exemptions. Let the care team know about your competitive status when scheduling.
