You know that skin covers underlying tissue, and that less skin necessarily means less tissue? But don’t take my word for this obvious point; you can look at other reliable sources:

- Less development of genital tissue, which may limit options for gender affirming surgery (bottom surgery) later in life.
Saying it’s “only an issue if the person goes on to transition” is a rather ridiculous argument. Can you really not think of any other issues with having (say) a penis that is only partially between pre-pubescent and adult-sized?
Yes, and the fact that there is still great disagreement among professionals should be concerning. Not with the disagreement, per-se–medicine is science, and science is often messy. But when the language from some sources sounds authoritative, and it disagrees with other authoritative sources, then maybe it should be considered with significantly less weight.
The NHS, incidentally, hedges things even further:
Little is known about the long-term side effects of hormone or puberty blockers in children with gender dysphoria.
Although GIDS advises this is a physically reversible treatment if stopped, it is not known what the psychological effects may be.
It’s also not known whether hormone blockers affect the development of the teenage brain or children’s bones. Side effects may also include hot flushes, fatigue and mood alterations.
“GIDS advises” is a typically British slam on their own division. Given that they plan on closing the clinic, I think it’s safe to assume that the position of GIDS does not match that of the NHS as a whole (which is clear given the surrounding text).
Much of the safety claims rest on the blocker’s use for precocious puberty. I.e., delaying it from (say) 9 until 12. And they are reasonably safe in that application, with caveats. But that safety data is not necessarily applicable toward delaying normal puberty.
Let’s try to do better than that. I almost said “it would be hard to do worse”, though I’m not sure that’s actually true.
