No mention of cognitive impairment, no mention of inability to orgasm. It's basically just bone density. Even the infertility thing is only mentioned when combined with "gender affirming" (ie, sex denying) hormone treatment. So yeah, they talk a bit about some of the negative side effects.
But they're still very much underselling how big the risk is, and how potentially bad the side effects are.
And you've badly misidentified what "reversible" even means, and the fact that there is no proof or even good evidence that they are reversible when used to treat gender dysphoria.
If you stay on these drugs long enough (and many patients do), you never go through puberty at all. Even by your own definition, that's not reversible.
