[Prolactinoma in the male. Physiopathological, clinical, and therapeutic features].
Among the various endocrine forms impotence associated with hyperprolactinaemia is discussed in this paper. A more relevant clinical picture is particularly due to prolactinoma. A marked reduction or suppression of libido and sexual power are mostly present; sometimes an altered spermatogenesis with oligospermia and infertility may be found; on the contrary galactorrhea and gynaecomastia are less frequent. Symptoms and signs of hypopituitarism or extrasellar growth may be found too. The main physiopathologic aspects as well as biochemical and instrumental diagnostic evaluation methods of prolactinoma in men are examined. The treatment may be pharmacological, surgical or radiant: indications and efficacy of each one are reported. A guide-line in case of macro- or microprolactinoma is explained too. With regard to pharmacological treatment, dopaminergic agonists have been available for more than twenty years and there is a wide experience with bromocriptine. Among the latest dopaminergic agonists, cabergoline is very interesting because it is effective, selective and long-term active; its pharmacological features are mentioned. At last, personal experience in three men, one suffering from micro- and two from macroprolactinoma recently treated with cabergoline is reported. Clinical aspects and hormonal and instrumental data before treatment are presented. Clinical and hormonal evaluations have been made after 2, 3 and 6 months of therapy and TAC control after the sixth month. The results allowed to verify the effectiveness of the drug.
