Athletics’ governing body has promised to respect the Court of Arbitration for Sport’s (Cas) decision on rules over testosterone levels in female athletes.
The IAAF has ruled some female runners with naturally high testosterone levels will have to race against men or change events, unless they take medication.
But Olympic and world 800m champion Caster Semenya has said she will fight the decision, calling it “unlawful”.
The IAAF and Athletics South Africa have agreed to honour any decision.
“The meeting was cordial with both organisations agreeing that the Court of Arbitration for Sport was the right body to arbitrate this matter and its final decision will be respected by both organisations,” said an International Association of Athletics Federations statement.
The rule, which comes into force on 1 November, applies to women who race in track events from 400m up to the mile.
Cas says an arbitration procedure has been opened and a hearing will be held at a later date.
Semenya, a two-time Olympic champion and three-time world champion, has previously been asked to have gender testing by athletics chiefs, but no results have officially been made public.
“It is not fair. I just want to run naturally, the way I was born,” said the 27-year-old South African.
Testosterone is a hormone that increases muscle mass, strength and haemoglobin, which affects endurance.
