The hon. Gentleman is exactly right, and he expresses my point succinctly. Why is the Secretary of State going ahead with a trial—experimenting on more children unnecessarily—when he has the data to analyse already? Why has he chosen to fund this trial? Is he worried about the children who will be put on a medical pathway that may lead to cross-sex hormones and a lifetime of medicalisation when they would have got better by themselves anyway? I want to talk about the age of these young people. The Medicines and Healthcare products Regulatory Agency warned in February that the youngest patients are at the greatest risk, and may end up on puberty blockers for a much longer period. They have a higher risk to fertility because sperm and eggs have not yet fully developed at Tanner stage 2, but this Government have chosen to include children of 11 or 12. Some will wonder why it is 11 for girls and 12 for boys—indeed, I was asked that question yesterday—but as a paediatrician I am aware that puberty starts earlier in girls than in boys. It is somewhat ironic that a trial based on the premise that girls could be boys recognises this biology, but I am glad that in this respect it does. However, that means some of the participants will be primary school-aged children with the merest form of puberty. How can they possibly meet the eligibility criteria, which includes “sufficient understanding of the treatment advantages and disadvantages, including discussion of fertility preservation”? How can a child of 11 understand what it means to lose sexual function, to be unable to have children when they are older, to have difficulties in thinking and to have weak bones? Remember that this Government think that 14-year-olds are not old enough to watch social media, but they think 11-year-olds are capable of understanding this.
