There are tons of nasty side effects that go with dwarfism; it's not as though it's _just_ being short. It can cause bowleggedness, hunchback, limited mobility of elbows, and all sorts of other issues [0] (yes, those refer to the specific kind of dwarfism this medicine treats). A parent can't subject his kid to those just so he can feel like his kid fits a "culture". It's wrong for the same reason mutilating girls' genitals to fit a "culture" is wrong. It is unethical to cause a child a lifetime of problems for personal gratification or because of a parent's insecurities. At least cochlear implants can be given at a later age; this is a developmental thing which a child cannot choose for himself at a later age.
