Gender Verification in Sports - History

History

United States Olympic Committee president Avery Brundage requested, during or shortly after the 1936 Summer Olympics in Berlin, that a system be established to examine female athletes. According to a Time magazine article about hermaphrodites, Brundage felt the need to clarify "sex ambiguities" after observing the performance of Czechoslovak runner and jumper Zdenka Koubkova and English shotputter and javelin thrower Mary Edith Louise Weston. Both individuals later had sex change surgery and legally changed their names, to Zdenek Koubek and Mark Weston, respectively.

• Perhaps the earliest known case is that of Stanisława Walasiewicz (aka Stella Walsh), a Polish athlete who won a gold medal in the women's 100 m at the 1932 Summer Olympics in Los Angeles, but who after her death in 1980 was discovered to have had partially developed male genitalia. (See below for genitalia as indicators of a person's sex.)
• Another Polish athlete Ewa Kłobukowska, who won the gold medal in women's 4x100 m relay and the bronze medal in women's 100 m sprint at the 1964 Summer Olympics in Tokyo, is the first athlete to fail a gender test in 1967. She was found to have the rare genetic condition of XX/XXY mosaicism and was banned from competing in Olympic and professional sports.
• Eight athletes failed the tests at the 1996 Atlanta Olympics but were all cleared by subsequent physical examinations.
• In 1976 Summer Olympics in Montreal, Princess Anne of the United Kingdom was the only female competitor not to have to submit to a sex test. She was a member of her country's equestrian team.
