In 2009 the South African track star faced intense scrutiny when she was accused of not being a woman. After rigorous physical and psychological tests it was determined that Semenya had both male and female chromosomes. Based on these findings it was uncertain whether or not the then 800-meter world champion would keep her title or be able to compete in the future as a woman. Despite having been suspended from competing for nearly a year, Semenya is back on track racing as a woman. Most recently, she competed in the IAAF World Challenge Dakar Grand Prix.
