The NCAA, the governing body for US collegiate sports, has issued a new policy that limits competition in women's sports to only student-athletes assigned female at birth. Announced on Thursday, the National Collegiate Athletic Association said its policy applied to all athletes and was effective immediately.

The NCAA changed its participation policy for transgender athletes on Thursday, limiting competition in women's sports to athletes assigned female at birth only. The move came one day after President Donald Trump signed an executive order intended to ban transgender athletes from girls’ and women’s sports.

The decision, effective immediately, came a day after President Trump signed an order barring transgender girls and women from playing in women’s sports at federally funded educational institutions.
