To the editor: MacAdams and colleagues (1) report a reduction in serum testosterone levels in patients receiving long-term glucocorticoid therapy and attribute this to an "alteration of hypothalamic GnRH secretion," because they found no accompanying increase in gonadotropin levels. They acknowledge that this finding is at variance with those in previously reported studies of acute glucocorticoid administration, which have indicated that glucocorticoids directly interfere with gonadal testosterone synthesis (2, 3). However, they are apparently unaware of our very similar 1985 report in which we documented the same decrement in total and free serum testosterone levels in asthmatics receiving chronic steroid
