Mack Beggs, 17, who is transitioning from female to male, had wanted to compete against other boys in the Texas state championship.
But officials refused to allow it because state sport regulations require athletes to wrestle according to their gender at birth.
Despite this Beggs was booed by people who thought he had an unfair advantage when taking on girls because he was taking drugs that increased his testosterone.
This had led to a parent of a girl trying to block him competing by filing a lawsuit.
But it didn’t work and Beggs beat Chelsea Sanchez 12-2 on Saturday to win gold at the Texas girls state championship in the 110-weight class.
‘That’s honestly what the spotlight should’ve been on, my teammates,’ he said after he won.
