[Diagnosis and treatment of idiopathic hypogonadotropic hypogonadism in men based on a clinical case].

A patient with tertiary hypogonadotropic hypogonadism was followed up for many years. On the basis of this observation the possibilities for a correct diagnosis with the gonadoliberin test are pointed out. A positive effect of the treatment with gonadotropic hormones, especially on the spermatogenesis, is established. Several other new therapeutic means which can be applied in these patients are discussed.
