Coe warns transgender athletes pose risk to integrity of women’s sport

Sebastian Coe has claimed that the “integrity and future of women’s sport” is at stake after the American swimmer Lia Thomas became the first transgender woman to win an NCAA swimming championship last week. The World Athletics president also called on the International Olympic Committee to introduce regulations that can be applied across every sport and insisted that “gender cannot trump biology”.

Thomas, who swam for the University of Pennsylvania men’s team for three seasons before starting hormone replacement therapy in 2019, made history by winning the 500-yard freestyle in Atlanta but has faced protests since starting to compete as a woman. Asked how important the challenge of transgender women is in athletics, Lord Coe said: “I think that the integrity of women’s sport – if we don’t get this right – and actually the future of women’s sport, is very fragile.”

Athletes with DSD (difference of sexual development) such as South Africa’s Caster Semenya have also been forced to restrict their testosterone levels for six months to be permitted to compete internationally over certain distances.

“There is no question to me that testosterone is the key determinant in performance,” Coe told the Daily Telegraph. “If you look at the nature of 12– or 13-year-old girls, I remember my daughters would regularly outrun male counterparts in their class, but as soon as puberty kicks in that gap opens and it remains. He added: “Gender cannot trump biology. As a federation president, I do not have that
