Have bought and just reading David Aaronovitch review - have learnt that this from review and blood is boiling already.
“‘A level playing field is a fallacy,’ says Dr Myron Genel, Yale professor emeritus of pediatric endocrinology. He is a member of the International Olympic Committee’s medical commission on issues regarding gender identity in athletics. “There’s so many other factors that may provide a competitive advantage,” Genel says. “It’s very hard to single out sex as the only one.” Look at the stats, Myron, for heaven’s sake."
Googled Dr Myron Genel and he looks like an arrogant Commander from Gilead. Slow hand clap for the man who destroyed women's sports. 
Review
David A is getting some abuse on Twitter for this review. Well done him for speaking out.
