The new rules will take effect from March 31 and apply to male-to-female athletes. A statement from the governing body Thursday said "the council decided to prioritize fairness and the integrity of the female competition before inclusion." World Athletics President, Lord Sebastian Coe told a press conference in Monaco that "the issue is thorny" and "we're not saying no forever." "Decisions are always difficult when they involve conflicting needs and rights between different groups, but we continue to take the view that we must maintain fairness for female athletes above all other considerations," Coe continued in an official published statement. The WA president added that the "integrity of the female category in athletics is paramount" and that the governing body "will be guided in this by the science around physical performance and male advantage which will inevitably develop over the coming years."

Aside from the ban, WA agreed to a 12-month working group that would further consider issues of transgender inclusion. The council also revealed that its new regulations were decided after a two-month consultation with "member federations, the Global Athletics Coaches Academy and Athletes' Commission, the IOC (International Olympic Committee) as well as representative transgender and human rights groups." On Thursday, the council also announced new rules surrounding the eligibility of athletes with Differences of Sexual Development (DSD). These new regulations will require DSD athletes to reduce their testosterone levels below a limit of 2.5 nanomoles per liter for a minimum of 24 months to compete internationally in the female category of any event.

This would impact two-time Olympic 800-meter champion Caster Semenya and Olympic 200-meter silver medalist Christine Mboma. World Athletics' latest decision follows a June 2022 ruling from swimming's governing body World Aquatics, which banned transgender women from female competitions if they experienced male puberty.

The ruling from WA was criticized by Stonewall, a U.K. charity group dedicated to gay, lesbian, bisexual, and transgender rights. In a statement, Stonewall said the WA decision was "so disappointing" and "their own statement recognizes that there are no trans women competing at an international level and that they have no specific evidence to justify the ban."
