Women's Tennis Association adopts SRY gene testing for 'equal athletic' competition

The Women's Tennis Association (WTA) has just become the latest sports organization to require players to take a genetic test to establish their eligibility to compete in the women's category.

The WTA's updated women's eligibility policy requires players to undergo a one-time screening for the SRY gene, which is found on the Y chromosome and is involved in male-typical sex development. Testing can be completed through a simple cheek swab, blood test or saliva sample.
