“World Athletics asserts the SRY gene is a reliable proxy for determining biological sex. But biological sex is much more complex, with chromosomal, gonadal (testis/ovary), hormonal and secondary sex characteristics all playing a role.”

Sex testing is not only invasive, it’s also inaccurate.
World Athletics’ mandatory genetic test for women athletes is misguided. I should know – I discovered the relevant gene in 1990
World Athletics says its genetic test for women ensures ‘the integrity of women’s sport’ – but science does not support this overly simplistic idea.
