Olympic 800m champion Caster Semenya has lost her landmark legal case against athletics’ governing body, the IAAF, which means she will have to take medication to reduce her testosterone if she wants to keep running on the international stage.

Aldrin Sampear is joined by a member of Semenya’s legal team of experts at Court of Arbitration for Sports professor Ross Tucker and UN ambassador Nosipho Mxakato-Diseko.
