title: [Induction of puberty by pulsatile luteinizing hormone releasing hormone (LH-RH)--therapy in a boy with Kallmann syndrome].
abstract: To induce the lacking development of puberty, a male patient with hypothalamic hypogonadism and anosmia (Kallmann's syndrome) was treated with pulsatile application of gonadotropin-releasing hormone (GnRH) to imitate the endogenous secretion of GnRH. The low-dose pulsatile GnRH treatment which was reported to be successful by various authors proved to be ineffective when administered to our patient subcutaneously as well as intravenously. Serum testosterone levels comparable to the lower normal values in adults and continuous progress of pubertal development were only achieved after increasing the dosage from 2 to 8 micrograms per pulse by subcutaneous application. The course of therapy is reported in detail.
