A major decision from the International Olympic Committee has ignited one of the most contentious debates in sport. From the 2028 Los Angeles Olympics onwards, transgender women — and some athletes with differences in sex development — will no longer be eligible to compete in the female category. The IOC says the move is grounded in science, fairness, and safety. Critics say the evidence isn’t settled, the policy goes too far, and the consequences could be profound. 

The decision follows years of growing pressure — from athletes, federations, and shifting political currents — and marks a sharp turn away from the IOC’s previous, more inclusive framework. So, what does the science actually say about performance advantages? How robust is the case for exclusion at an elite level? And what happens when global policy filters into national and grassroots sport? 

Ciara Doherty is joined by Dr Blair Hamilton — a researcher in sport policy and a former footballer directly affected by similar rules in the UK — to explore the reality behind the headlines, the human impact, and what comes next as the world looks ahead to LA 2028.
