World Athletics has announced that it will begin genetic testing for all female track and field athletes in the future, according to the Washington Post. The new policy could have an impact on Olympic athletes in the near future.

World Athletics President Sebastian Coe said the testing plan is “not just talking about the integrity of female, women’s sport but actually guaranteeing it.”
