WTA mandates genetic sex testing for all players on the women’s tour

The Women’s Tennis Association will require all players to undergo mandatory genetic sex testing in order to compete on the professional tour.

The updated women’s eligibility policy will demand a cheek swab, blood, or saliva sample from every competitor.

This single lifetime assessment specifically tests for the SRY gene, a component of the Y chromosome responsible for male characteristic development.

Only individuals returning a negative result for the gene will receive immediate clearance to participate on the elite tennis circuit.

Medical assessments and disciplinary action

Competitors who test positive will not face an automatic ban but must undergo further medical evaluation before returning to the court.

The governing body has also introduced strict compliance measures to enforce the newly established screening regulations.

Athletes refusing to submit to the test must sign a document acknowledging they could face severe disciplinary action.

Moving away from testosterone thresholds

The organisation’s previous guidelines, updated as recently as 2024, permitted transgender women to compete provided they maintained lowered testosterone levels for two consecutive years.

This policy shift aligns the tour with a growing movement across international sports focusing on biological sex rather than hormonal suppression.

There are currently no known transgender women participating at the highest level of professional tennis.

Aligning with global sporting standards

The latest mandate mirrors recent regulatory changes implemented by other major international sporting federations.

World Athletics introduced comparable regulations requiring a one-time gene test for female category competitors, which were scheduled to take effect in September 2025.

World Boxing also established mandatory SRY testing for athletes entering the women’s category in May 2025.
