It is so difficult to get research on children through ethics committees - that's research that could potentially improve treatment for children with chronic lifelong illnesses.
So how this got through I don't know.
Use of puberty blockers is for children with measured precocious puberty - and it is acknowledged that this has to be done carefully to delay puberty for a short while only.
What is the physical benefit for the child? How will this help their physical body?
Are they basically going to say that because it makes the child happy (measured only 1 year after intervention with the question 'how happy are you now 1-10') and ignore any physical damage that will happen much later on.
The power of cosmetic surgery and pharmaceutical companies disgust me - they are damaging young people every day, making them hate their healthy bodies in various ways and encouraging them to hurt themselves by using their services and products.
