"They're going to be doing some peeking and poking," said Lynn Cannon, chairman of the women's track and field committee of The Athletics Congress. That about sums up track and field's new approach to determining an athlete's gender. The International Amateur Athletics Federation has adopted a visual inspection instead of conducting the standard chromosome test. Gender tests were first introduced in 1966 to prevent men from seeking an advantage by competing as women. At least no one has to study for that chromosome tes anymore.
