An appeal hearing is underway at the Swiss-based Court of Arbitration for Sport (CAS) in a landmark case with wide-reaching consequences for gender politics and science.
The scheduled five-day appeal case is among the longest ever heard by the sports court and a verdict is expected by the end of March.
The IAAF wants to require women with naturally elevated testosterone to lower their levels by medication before being allowed to compete in world-class races from 400 metres to one mile.

Decisions of the CAS can be appealed to Switzerland’s Supreme Court.
