INDUCTION OF PUBERTY LONG-TERM TREATMENT WITH HIGH-DOSE LHRH

Abstract
Gonadotropin releasing hormone 500 .mu.g was administered twice daily to 4 patients (2 male, 2 female) with hypogonadotropic hypogonadism due to LHRH [luteinizing hormone releasing hormone] deficiency, for a minimum of 1 yr. Despite initially encouraging biochemical responses and physical changes in all 4 patients, gonadotropin responsiveness waned, sex steroid levels were not maintained and pubertal development did not occur. This diminishing responsiveness appears to be a severe limitation on the use of LHRH as a therapeutic agent.
