World Athletics Mandates SRY Test for Female Athletes
World Athletics is making female athletes take a gene test to make sure they are biologically female.
This is because people with XY chromosomes (usually male) tend to have a performance advantage over people with XX chromosomes (usually female) due to hormones.
The test checks for the SRY gene, which usually starts male development.
Some experts are worried the test might not be perfect and that it could be unfair.
Athletes who test positive might still be able to compete, just not in the female category, unless they have a specific condition.
Some countries have already pushed back, and the tests will begin soon.
World Athletics mandates SRY gene tests for female athletes to compete.
The SRY gene, found on the Y chromosome, triggers male development.
The tests, conducted via cheek swab or blood test, begin September 1.
Critics question the test's accuracy and ethical implications.
Some athletes who test positive will be allowed to compete in other categories or seek further assessment.

Critics of SRY Testing
World Athletics Stance
Test Simplicity vs. Fairness
Critics of SRY Testing
The test is overly simplistic.
World Athletics Stance
World Athletics believes the test is important for ensuring fair competition.
Test Accuracy vs. Fairness
Critics of SRY Testing
The SRY test might not reveal small mutations, it does not determine how male or female an athlete may be, making it an inaccurate test
World Athletics Stance
World Athletics believes the test is a very important step in ensuring there is no biological glass ceiling.
