South Africa's Caster Semenya, whose gender is in controversy, won women's 800 meters gold at the 12th World Athletics Championships on Wednesday, Xinhua reported.
The 18-year-old won gold with 1 minute, 55.45 seconds, while defending champion Janeth Jepkosgei Busienei of Kenya had to take silver with 1:57.90. Jennifer Meadows of Britain finished third with 1:57.93.
Hours before the race, the ruling body IAAF said that a gender test had been conducted on Semenya to confirm whether she was a real woman or not. But the test result could not be available until some time later.
There had been doubts about Semenya's gender because of her masculine physique. But the IAAF said she must be allowed to run as there is still no firm evidence to show that she is not a woman.
