Our take: For the London Games, officials are going by a new set of rules that shifts the focus from DNA to testosterone, a hormone that aids muscle development, endurance and speed to distinguish men from women athletes.
Of all the obstacles athletes have had to overcome to compete in the Olympics, perhaps the most controversial has been the gender test.
Originally designed to prevent men from competing in women's events, it is based on the premise that competitors can be sorted into two categories via established scientific rules. But the biological boundaries of gender aren't always clear.
Consider the Spanish hurdler Maria Jose Martinez-Patio. A gender test revealed that she had a Y chromosome, which normally makes a person male. She also had complete androgen insensitivity syndrome, or CAIS, which prevented her body from responding properly to testosterone and caused her to develop as a woman.
