Athletics governing body, the IAAF, has received the results of Caster Semenya's gender tests and is trying to get in contact with her, Beeld reported on Thursday.
The results would only be made public once other experts had studied them and the athlete had been informed, International Association of Athletics Federations spokesman Nick Davies told the newspaper from Switzerland.
Davies said, "we can't afford to make any mistakes" because Semenya's case had become a international human rights issue and "because it's become a political issue in South Africa."
According to Davies the IAAF's requests to Athletics South Africa to get in touch with Semenya had fallen on deaf ears.
"ASA's actions can have serious consequences for Semenya if we don't get to speak to her soon. It comes down to her not wanting to co-operate."
He said it was a "unique problem" and the IAAF had no rules on how to handle it. "It's important for us to discuss the results of the tests with her," he was quoted as saying.
Semenya won gold in the 800m race at the world championships in Berlin last month. – (Sapa, September 2009)
