The Women's Tennis Association (WTA) has introduced mandatory one-time genetic testing for the SRY gene for all players on the tour [1].
The policy marks a significant shift in how the organization regulates eligibility, moving toward a standardized biological verification process for every athlete regardless of their history. This change aims to align the tennis tour with broader international sporting standards and address long-standing debates over competitive equity in women's sports.
According to the organization, the testing is designed to verify biological sex [4]. The WTA said the move is intended to ensure fair competition across the global tour [5]. By implementing this requirement, the association aligns its protocols with existing policies established by the International Olympic Committee and World Athletics [4].
The new requirement became effective this week, starting on Tuesday [2]. All players currently competing on the WTA Tour must undergo the procedure [1]. The association said the genetic test is a one-time mandatory requirement [1], a measure intended to create a permanent record of eligibility for each athlete.
While the WTA did not provide specific details on the logistics of the testing sites, the mandate applies to all participants across the global tour [2]. The focus on the SRY gene allows the organization to identify the presence of the sex-determining region Y, which is the primary biological marker used to distinguish between male and female genetic profiles.
This systemic approach to verification replaces previous case-by-case reviews or reliance on birth certificates. By making the test universal, the WTA avoids targeting specific individuals and instead applies a single biological standard to the entire field of competitors [1].
“The WTA has introduced mandatory one-time genetic testing for the SRY gene for all players on the tour.”
The WTA's decision to implement universal genetic testing reflects a broader trend in international sports toward biological rather than self-declared or document-based gender verification. By aligning with the IOC and World Athletics, the WTA is attempting to insulate itself from legal and competitive challenges regarding biological advantages. This move signals a prioritization of biological sex over gender identity in the definition of women's athletics, potentially setting a precedent for other professional women's sports leagues.
