The Women's Tennis Association (WTA) has implemented a new policy requiring players to undergo genetic testing to confirm their eligibility to compete in women's tennis.This follows a previous rule allowing biological males with testosterone levels below a certain threshold to compete.The updated policy mandates sex screening for the SRY gene, typically associated with male sex development.Players must pass a cheek swab, blood test, or saliva sample to be eligible for the WTA Tour.A positive result triggers further medical assessment before competition.

Martina Navratilova, a vocal advocate for excluding trans athletes from women's sports, endorsed the policy, emphasizing the importance of maintaining fair competition.The WTA stated the policy aims to promote equal opportunities and fair play, acknowledging the sensitivity of the issue.

Similar measures have been adopted by organizations like World Boxing and World Athletics, with the IOC planning to implement sex tests for the 2028 Olympics.

The policy has sparked debate about inclusivity and fairness in sports, balancing the rights of athletes with the integrity of competitive categories.
