Foekje Dillema (Template:IPA; 18 September 1926Template:Dash5 December 2007) was a Dutch track and field athlete. She competed in sprinting where she was a rival of Fanny Blankers-Koen. When she refused a sex verification test at age 24, she was banned from competition by the International Association of Athletics Federations in 1950. After her death, it was determined that she was an intersex person.

Career

About a month later, she competed in the Dutch Championships in Eindhoven, where she ran 12.5 s in the 100 metres, resulting in 4th place in the heats, and 26.2 s in the 200 metres, resulting in 4th place in the final.<ref>"Athletiek Jan Lammers Nederlands kampioen 200 meter" (in Dutch), Leeuwarder Courant, 12 July 1948.

1949

In 1949, Dillema did not compete in the Dutch Championships due to an injury of her thigh.<ref>"Athletiek Foekje Dillema in de nationale athletiekploeg" (in Dutch), De Heerenveensche Koerier, 11 July 1949. Retrieved 30 September 2023.</ref>

Dillema was named "athlete of the match" in 1949 after winning the 100 metres and 200 metres race during a tournament in London. She was an important rival for another Dutch athlete Fanny Blankers-Koen, who won four gold medals during the 1948 Summer Olympics.Template:Citation needed

1950

In 1950, Dillema was banned from competition for life by the IAAF. Dillema had refused to go to a mandatory sex test for the European championships in Brussels in August 1950. Dillema was the first subject of a mandatory gender verification. The IAAF introduced mandatory sex verification in 1950 and continued this practice until 1992. Dillema's national record of 24.1 seconds for the 200 metres was erased.<ref>Template:Cite web</ref>

On 13 July 1950, Dillema was stopped on her way to an international meeting in France by the Dutch athletics authorities and expelled for life from competition.<ref name="dohle2008">Dohle, M.

After the ban

After Dillema was banned from competition, she returned home to Friesland and did not leave her house for at least one year. She lived a quiet life in her home town afterwards and always refused to speak on the subject.<ref name="dohle2008"/>

She died on 5 December 2007 in Kollum, Netherlands.<ref name="tlc2021"/>

Posthumous testing

Dillema, having the typical female phenotype, was designated female at birth, raised as a girl and lived her life as a woman. After her death, a forensic test on body cells obtained from her clothing showed signs of a Y-chromosome in her DNA. She may have been a genetic mosaic, having cells with either 46,XX (female) or 46,XY (male) chromosomes, in approximately a one-to-one ratio, in her skin. The forensic report speculated that Dillema developed from a zygote with an XXY genotype that promptly divided into a half XX, half XY embryo through nondisjunction. Dillema was probably a 46XX/46XY woman.<ref>Template:Cite journal</ref> This is also known as ovotesticular disorder of sex development (DSD) or true hermaphroditism.<ref>Andere Tijden Sport – Het mysterie Foekje Dillema. NOS Dutch broadcast 2008</ref>

Her biographer Max Dohle concludes that Dillema, having a Y-chromosome, would never have been allowed to race in the last 45 years. The Barr body test (1966) as well as the test based on PCR (1992) scanned for a Y-chromosome or an SRY-gene on the Y-chromosome. All female athletes with a Y-chromosome were expelled from competition from 1966 until 2011.<ref name="KatrinaKarkazis">Template:Cite journal</ref>

Dohle concludes that Dillema was an intersex individual who had ovotesticular DSD. She had an operation on her glands in 1952. During the operation, testes or ovotestes were removed. The SRY-gene on the Y is the testis determining factor, so Dillema may have had infertile testes or ovotestes palpable in her groin. These ovotestes produce more testosterone than ovaries.

Rehabilitation

Shortly after Dillema's death, the director of the Royal Dutch Athletics Federation apologized to her family for the manner of her suspension and her personal best in the 200 metres was reinstated.<ref name="tlc2021"/>

In 2011, a street in Amsterdam was named after her.<ref>Template:Cite news</ref>

In 2014, Ids Willemsma made a sculpture commemorating Dillema, currently installed in Leeuwarden.<ref>Template:Cite web</ref>
