In a 1953 editorial entitled "The Need for an Inhibitor of Gonadotropin,"Lawson Wilkins noted that a "method of suppressing the secretionof pituitary gonadotropins . . . might lead to the preventionor control of sexual precocity."1 Almost 30 years later, Crowleyand colleagues reported successful suppression of early pubertyin a two-year-old girl with the use of a long-acting analogueof a luteinizing hormonereleasing hormone (LHRH) agonist.2In the intervening years, the nature of the hypothalamicpituitarygonadalaxis was elucidated, LHRH was isolated, and maturational changesin the reproductive axis were characterized (Figure 1).
