The NCAA faced calls to follow in the footsteps of World Athletics and enact gender tests for athletes who want to compete in the female category.

It remains unclear when the tests will begin but Coe says doing so is designed to maintain the "integrity of competition."

The planned changes include reinstating a version of chromosome testing that was discontinued in the 1990s, requiring athletes who compete in the female category to submit to a cheek swab or dry blood-spot test for the presence of a gene that indicates whether the athlete has a “Y” chromosome present in males.
