World Athletics Revives Gender Testing in Women's Sport

World Athletics is making female athletes take a test to check their genes before competing.

This test looks for a 'Y' chromosome, which is usually found in males.

Some people are worried because in the past, similar tests caused problems for athletes, like Spanish hurdler María José Martínez-Patiño.

This athlete lost friends and faced shame.

Some people think it is unfair and worry about making the tests mandatory.

Others see it as a way to keep competition fair in sports.

It is still debated on how this will impact the female athletes.
