In most sports, men compete against men and women compete against women. That is generally considered fair, because men are faster, more powerful and have greater endurance.
But there is an ongoing controversy about transgender women - people who were born male and now identify as women. Is it fair for them to compete in the women’s sport category or do they have an advantage?
A study in the British Journal of Sports Medicine recently added to the debate with an analysis that found the strength and fitness of transgender women is “comparable” with that of women.
More or Less looks into the research to explain what it does, and does not, say.
