Damnthatones, for well over a decade my work involved a constant awareness and understanding of medical ethics. One principle is that you only endanger a child's fertility if the situation is life and death. Cancer treatment, for example. The laissez-faire attitude of so many transactivist groups towards the medicalization of gender questioning kids is a genuine cause for concern.
There are fashions in medicine just as in other fields, and some of these fashions have caused significant harm. The most obvious is probably eugenics, but there have been a number of others. The current trans vogue fulfills the criteria for medical fashion. It arose very quickly, is unsupported by respectable research and yet has achieved almost universal acceptance. Voices urging caution are ignored or treated with contempt. When the bubble finally bursts a medical fashion usually ends as fast as it began.
In a decade or so the court hearings, the class actions are likely to start, cases from people whose healthy bodies have been damaged, who were sterilised as children. When that time comes, many of those now promoting trans ideology will claim that they always had their doubts.
