Giving the latter group exogenous growth hormone is futile, because their immune systems react to the “foreign” protein by producing antibodies. Although the hormone may stimulate growth for a short period, the antibodies soon bind and neutralize it.
给后者注射外源性生长激素于事无补，因为他们的免疫系统会对“外来”蛋白质产生抗体。尽管激素可以在短期内刺激生长，但其自身抗体很快就会对外来激素进行绑定及中和。
