SRY Test – Genetic Examination for Female Athletes
SRY Test – Genetic Examination for Female Athletes
A genetic test intended for female athletes to determine the absence of the SRY gene, which triggers testosterone production and the development of male sexual characteristics. This gene is normally located only on the Y chromosome, and therefore should not be present in women. However, in rare cases, it may appear — for example, through the transfer of part of the Y chromosome — and may influence hormonal balance, athletic performance, or reproductive health.
DETAILED INFORMATION
Starting September 1, 2025, World Athletics will require all registered female athletes to undergo the SRY test to ensure fair and consistent conditions in women’s categories.
The examination helps to:
-
Exclude genetic variations in female athletes,
-
Clarify hormonal imbalances or atypical development of sexual characteristics,
-
Meet the new requirements of sports institutions.
Gene / specification: SRY gene (presence / absence)
Sample type: blood or buccal swab (oral swab) – a simple and painless procedure.
The test is suitable for female athletes who wish to confirm their genetic profile, as well as for physicians conducting additional hormonal or sports screening.
If needed, we recommend a genetic consultation to explain the results and their significance.
You will receive the result within 10 working days.

Analysis
Our team of experienced professionals will analyse the sample using the latest methods and technologies.4
Result
After the test has been evaluated, you will receive a detailed and easy-to-understand laboratory report, or a consultation with a clinical geneticist will be recommended.Frequently Asked Questions
The SRY test is a genetic examination designed for female athletes to determine whether the SRY gene is present. This gene triggers testosterone production and the development of male sexual characteristics. The test helps detect genetic variations and explain hormonal imbalances.
From September 1, 2025, World Athletics requires all registered female athletes to undergo the SRY test to ensure fair and consistent conditions in women’s categories.
The test is carried out from a blood sample or a buccal swab (cheek swab). It is simple, non-invasive, and painless.
The test is intended for female athletes who want to confirm their genetic makeup, as well as for medical professionals conducting hormonal or sports-related screenings.
A positive result indicates the presence of the SRY gene, which is normally found only on the Y chromosome. In women, this may influence hormone levels, sexual development, and athletic performance.
