'A complex and emotive process': World Rugby backs guidelines to exclude transgender women from elite competitions

World Rugby has become the first global sports federation to recommend that transgender women do not participate in the elite and international levels of the women's game.

The organisation published a statement on Saturday that, while not strictly banning their inclusion in elite teams, recommended they be excluded "on safety grounds".

However, national unions have been allowed to make their own policy decisions at the community level of the game while transgender men remain permitted to play men's contact rugby in all forms.

The organisation's new policy comes after what it describes as a "comprehensive, collaborative and inclusive review" of existing guidance that concluded that "safety and fairness cannot presently be assured for women competing against transwomen in contact rugby".

It added it was committed to "regularly reviewing the guidance to monitor and consider any new evidence or research".

"This has been a complex and emotive process, but a necessary one," said Dr Araba Chintoh, who chaired the review.

"We set out to determine whether it would be possible to maintain inclusion in contact rugby based on the available research and evidence and rugby's unique context of combining strength, power, speed and endurance in a physical, collision environment.

"As we progressed through a comprehensive and inclusive review, it became clear there are compelling evidenced safety considerations which we simply cannot ignore.

"Unions will be able to exercise flexibility on a case-by-case basis at the community level of the game, for which the unions are responsible, while World Rugby will continue to prioritise inclusion strategies to ensure that the trans community remain an active, welcome and important member of the rugby family."

World Rugby chairman Sir Bill Beaumont added: "Rugby is a welcoming and inclusive sport and, while this has been a difficult decision to make, it has been taken following comprehensive consultation and engagement and for the right reasons, given the risk of injury.

"That said, we recognise that the science continues to evolve, and we are committed to regularly reviewing these guidelines, always seeking to be inclusive."

World Rugby's previous transgender policy followed the International Olympic Committee's policy, which currently states that transgender women must suppress testosterone levels for at least 12 months before competition.
