Overview
- The WTA board approved the policy on July 21, 2026, requiring all players to take a single genetic screen for the SRY gene to establish biological sex before competing on the tour.
- The test checks for the SRY gene typically found on the Y chromosome and can be done by cheek swab, saliva or blood sample, with a positive result triggering further medical review.
- Top players gave mixed tones in Toronto this week: Aryna Sabalenka backed the move on fairness grounds, Jessica Pegula described player briefings and an education effort, and Coco Gauff said she supports the trans community while understanding the fairness rationale.
- Several players said many learned of the rule only when it was announced, and the WTA plans to begin administering tests at upcoming tournaments with Cincinnati identified as an initial testing site.
- The rule replaces testosterone-based guidance in practice and includes medical exceptions for conditions such as Complete Androgen Insensitivity Syndrome, and it is expected to face legal, ethical and human-rights challenges as it is implemented.
