1 Aryna Sabalenka on Monday offered her full support for new mandatory sex testing designed to keep men out of women’s sports. The testing has the simple aim of keeping male imposters off the women’s courts. As Breitbart News reported, potential players who test negative for SRY are immediately qualified to play in the women’s category. The WTA is not alone in seeking to keep men out of the female sports arena. The International Olympic Committee also recently updated its policies and implemented sex testing for the upcoming 2028 Olympics scheduled for Los Angeles.
