Former Polish sprinter Marcin Urbaś has urged an Olympic victor get tested to confirm her sex. 

Sprinter Christine Mboma was disqualified from running in the 400-meter event at the Olympics due to a naturally high testosterone level as Blavity previously reported. She is one of several cisgender, Black women from Africa who have been hindered by the gender rules set by World Athletics.

After securing the silver medal in the women’s 200-meter race, Urbaś said she needed a sex-reaffirming test to confirm she is “definitely is a woman.”

“I would like to request a thorough test on Mboma to find out if she definitely is a woman,” Urbaś told Spanish sports news outlet Marca.

After the Namibian athlete ran the race in 21.81 seconds, the retired sprinter said his time was 22.01 seconds when he was her age. 

“She has the parameters of an 18-year-old boy,” Urbaś said according to LGBTQ Nation, adding that Mboma’s “construction, movement, technique” are also proof that she isn’t a woman.

Polish Sprinter, Marcin Urbas asked Tokyo Olympics organizers to test Namibian Teen, Christine Mboma to find out if she is a woman, after she ran a Semi Final time of 21.97 seconds in the women’s 200m race.

Urbaś, who set the world record for the 200-meter dash at the 1999 World Championships, claimed Mboma put her competition at a disadvantage. 

“It is a clear and insolent injustice against women who are definitely women,” he said.

World Athletics requires the women to use medications to lower their testosterone levels in order to compete. Although the organization bans women with high testosterone level, saying it gives them a natural advantage over other women, it does not have a similar rule limiting natural hormone levels for male athletes, LGBTQ Nation reported.

Mboma was still able to compete in the 200-meter event after failing the test because the rule only restricts testosterone levels in races between 400 meters and one mile. Some of the other athletes affected by the rules include Beatrice Masilingi of Namibia, Caster Semenya of South Africa, Francine Niyonsaba of Burundi and Margaret Wambui of Kenya.
