In an interview with the BBC, Sebastian Coe, chairman of the International Athletics Federation, WA, says that he welcomes the decision of the International Swimming Federation, Fina.

- It's as it should be.

We have always believed that biology trumps gender and want to continue to review the rules in line with this.

We follow science and study, investigate and contribute to the growing number of proofs that testosterone is the key to achievement, says Coe.

Rules should be discussed

- We will discuss our rules at the end of the year.

WA has already introduced maximum levels of testosterone for women in a number of running disciplines.

This after the South African Caster Semenya, who is hyperandrogynous and thus has a naturally high testosterone world, became so superior in 800 meters.

- We did not want to stigmatize.

But when it comes to justice, then for me it is not negotiable, says Coe.
