Olympic host Beijing has set up a sex determination lab to test female Olympic athletes suspected to be males, state media reported Sunday.
Experts at the lab, located at the Peking Union Medical College Hospital, will evaluate dubious cases based on their external appearance and take blood samples testing sex hormones, genes and chromosomes, Xinhua news agency said.
Sex testing has been routine at the Olympics and other sports events for decades, triggered by fears that male athletes sought to cheat by posing as women.
Indian athlete Santhi Soundarajan was stripped of an Asian Games silver medal in 2006 after failing a gender verification test.
