The Science of Eligibility: The SRY Gene Test

The cornerstone of the new policy is the SRY (sex-determining region Y) gene test, which will be conducted via saliva, cheek swab, or blood sample.

The Rationale: The IOC maintains that the presence of the SRY gene is a permanent biological marker of male sex development.

Frequency: The screening is a one-time requirement in an athlete's career.

Alternative Classifications: Athletes with an SRY-positive screen remain eligible for male categories, mixed categories (in designated male slots), or any "open" category established by sports federations.
