My noble friend is absolutely correct: one of the main findings from the Cass review was that more research has to be done in the whole space of puberty blockers. The NHS is moving on that as we speak. At the same time, I can assure the House that, from now on, no puberty blockers can be prescribed unless they are part of that research programme, because it is vital that that does not happen as a matter of course until we understand far more about this subject.
