World Athletics introduces gene test for female category

The test for the SRY gene – which is part of the Y chromosome and causes male characteristics to develop – can be conducted via a cheek swab or blood test.

If the test is negative for the Y chromosome, the athlete is eligible to compete in the female category.

If it is positive, they can compete in the female category in non-world ranking competitions or in another category other than the female one.

It is a test to be taken once in a lifetime and will be overseen by member federations.

“It is really important in a sport that is permanently trying to attract more women that they enter a sport believing there is no biological glass ceiling,” said World Athletics president Lord Coe.

In a frequently asked questions page published by World Athletics, the test is described as being “extremely accurate” and states “the risk of false negative or positive is extremely unlikely”.
