title: A patient with hypogonadotropic hypogonadism successfully treated by long-term pulsatile administration of luteinizing hormone-releasing hormone.
abstract: A male patient with hypogonadotropic hypogonadism has been treated by pulsatile administration lf luteinizing hormone-releasing hormone (LHRH) (20-25 micrograms, every 2 hours, sc) for 4 years 6 months. His plasma testosterone (T) concentration began to increase after 4 weeks of treatment and reached the normal range in week 5. He showed complete secondary sexual development after 1 year of treatment. His sperm count was normalized after 1 year of treatment. He was married after 29 months of therapy, and has a healthy male child. Blood type tests showed his paternity of the child. During the long duration of pulsatile LHRH therapy, his gonadotropin secretion has been stimulated by LHRH and his T level has been maintained with no observable side effects. There are no other reports of patients treated by pulsatile LHRH injection for such a long duration, but finding in this patient indicated that long-term pulsatile LHRH therapy is a useful and safe method for treatment of hypothalamic hypogonadotropic hypogonadism.
