did you see this bit at the end? Maybe they thought noone would get that far...
"What does medicine say?
Professor John Brewer, professor of applied sport science at St Mary's University, told BBC Radio 5 Live: "Whether we like it or not, genetically the very best males will nearly always beat the very best females in most sports where physicality is critical.
"If you have those physical and physiological characteristics of a male athlete and you are competing in a female environment, then you will inevitably do extremely well and have an advantage."
Brewer says males "tend to have more testosterone" that stimulates muscle growth and their "legacy physiology" (larger heart and lungs) does not necessarily change despite the transition process.
He added: "So, inevitably, when you go into high-performance sport, where the difference between success and failure is quite small, that 'legacy physiology' alongside the muscle growth testosterone creates will give, almost inevitably, transgender athletes/individuals a physiological and indeed a performance advantage."
