Like beauty pageants only different. Today they use a more accurate polymerase chain reaction test to determine pure, authentic women. Ewa Klobukowska, a Polish sprinter, was the first woman to fail the Barr test after having passed a visual inspection of her body the previous year. Klobukowska was stripped of her Olympic and other medals and removed from the competition. She, like six women in a thousand, have XXY chromosomes.
Humans exist within a broad range of chromosomal and hormonal possibilities.
Some men are born without testicles. Gender is determined by a combination of chromosomes, hormones, gonads, external genitalia and the assigned gender given at birth. Sexual testing continues today and disqualifies as many as 12 women during the Olympic Games. In 1985 Kirsten Wengler, suffered the horror of a false positive test before an international swim meet. The doctors even took it upon themselves to inform her that she might be also be unable to bear children.
