The development of LHRH-related peptides has been very rapid since the elucidation in 1971 of the structure of LHRH (see reviews by Schally et al., 1981, Yen, 1983, Swerdloff and Heber, 1983, Sandow, 1983). Today, the established clinical role for synthetic LHRH is in stimulation of gonadal function by pulsatile activation of gonadotrophin secretion (Knobil, 1980, Leyendecker et al., 1980, Hoffman and Crowley, 1982). LHRH analogues are predominantly used for reversible suppression of gonadal steroid secretion. The therapeutic potential of agonists and antagonists of LHRH is exerted through different mechanisms of action. Agonists stimulate gonadotrophin release at low doses, when given at suitable intervals so that pituitary sensitivity can recover between stimulations. At higher doses, they suppress pituitary function when given repeatedly. Several important clinical indications are now studied based on reversible suppression of pituitary and gonadal function by agonists. The LHRH antagonists block the action of endogenous and exogenous LHRH for extended time periods, and cause reversible pituitary-gonadal involution without a stimulation phase. Antagonists are now studied in preclinical animal models, and the inhibitory activity has been confirmed in humans
