Can growth hormone treatment in boys without growth hormone deficiency impair testicular function?

Abstract

Four young male subjects (age range, 17 4/12 to 25 5/12 years), previously treated with human growth hormone for non-growth hormone-dependent short stature, showed reduced testicular volume and hypergonadotropic hypogonadism. They also showed impaired spermatogenesis and altered testicular texture as determined by ultrasonography. No clinical or laboratory finding showed disease associated with testicular dysfunction. An unfavorable gonadal outcome could occur in boys without growth hormone deficiency treated with human growth hormone.
