Caster Semenya, the 800 metres world champion, will not return to competitive athletics until her gender verification case has been resolved, Athletics South Africa (ASA) announced on Tuesday.
Semenya underwent gender verification tests after she won the women's 800 at the Berlin world championships last August but the International Association of Athletics Federations (IAAF) has yet to reveal the results of the tests.
Local media have reported that Semenya was due to compete in an athletics meet in Stellenbosch, South Africa on Tuesday.
"The IAAF have given the assurance of completing the medical process speedily and have requested that ASA abide by the world body's decision not to allow Semanya to participate in track and field events until the process has run its course," ASA administrator Ray Mali said in a statement.
Semenya was allowed to keep her 800 gold medal but she has not competed since undergoing the tests.
