A judgement from the European Court of Human Rights has found that Caster Semenya was discriminated against by rules which forced her to lower her testosterone levels in order to continue competing.
The 32-year-old, a two-time 800 metres Olympic champion, was legally identified as female at birth but has a condition which means her body naturally produces higher levels of testosterone than women without the condition.
She has been unable to compete at her favoured distance since 2019, following the introduction of limits on testosterone levels for female athletes which would have forced her to use medication.
