"As a result, the new guidelines do not recommend that transwomen play women’s contact rugby on safety grounds at the elite and international level of the game where size, strength, power and speed are crucial for both risk and performance, but do not preclude national unions from flexibility in their application of the guidelines at the community level of the game. Transmen are permitted to participate in men’s contact rugby. "
