World Athletics announced that it is in consultation with member federations regarding a proposal that would impose stricter testosterone limits on transgender women athletes competing in women's track and field events.
The proposal stops short of calling for an outright ban on trans athletes, and it claimed to have reached its "preferred option" after looking over a number of recent and past scientific studies as well as field reports.
The option being discussed would cap the maximum amount of plasma testosterone for transgender women and those with differences in sex development at 2.5 nanomoles per liter, half of the current limit of 5 nanomoles. Additionally, the athlete would have to stay below that level for two years instead of just one.
A final decision over the proposal will be made by the council in March.
