How the controversy unfolded
Caster Semenya bursts onto the global stage aged 18 after winning world 800m gold (below) hours after news leaked that the IAAF had conducted a gender verification test on the South African.
Semenya’s coach resigns, citing a failure to protect his athlete. Athletics South Africa president Leonard Chuene admits he lied about Semenya being subjected to gender testing.
Having turned up to a track meet in Stellenbosch, South Africa, Semenya is turned away as the IAAF has not yet released its findings of her gender test. Her suspension is lifted in July.

Indian sprinter Dutee Chand (below) wins her case at the Court of Arbitration for Sport, resulting in the suspension of the IAAF’s hyperandrogenism regulations pending further scientific evidence.
The IAAF confirms its updated eligibility regulations only for events from 400m to the mile. Women affected are deemed athletes with “Differences of Sexual Development” (DSD).
Semenya decides to challenge the IAAF rules, taking her case to CAS. Athletics’ world governing body confirms it will delay its implementation of the rules, pending the CAS verdict.
CAS puts its ruling back to late April, having been unable to hit its original March deadline. The IAAF says it still hopes to have them in place for this year’s World Championships in Doha, Qatar.
The IAAF announces new eligibility rules forcing women with hyperandrogenism (excess levels of testosterone) to take testosterone-lowering medication.
