The International Olympic Committee's new transgender guidelines for sports have been delayed again because of "very conflicting opinions" and are now unlikely to be published until after next February's Beijing Winter Olympics, three years later than originally planned.

The news was revealed by the IOC's science and medical director, Dr Richard Budgett, who said the forthcoming advice for international sports federations would "prioritise inclusion" and "avoidance of harm".

As things stand, the IOC suggests trans women should be allowed to compete in the women's category if they reduce their testosterone for 12 months – although individual sports federations are allowed to come up with their own rules.

However, speaking to a Council of Europe conference on protecting and promoting the human rights of intersex and transgender athletes in sport competitions, Budgett said the IOC's approach would shift. "There'll be broad high-level guidelines – more like a framework," he said. "It's the international federations who will determine the specific rules for their sports and their events.

"The particular changes from 2015 are the emphasis on the priority of inclusion, and on the avoidance of harm, but always bearing in mind the importance of fair and meaningful competition. We still have to agree on the framework. It's challenging. But it will be published in a few months' time – at the latest just after the Beijing Olympic Winter Games.

"We're very aware that sex, of course, is not binary. It's a continuum. The sectors overlap. And so the solutions are not essentially going to be binary."
