Male hyperprolactinemia:effects on fertility.


Male hyperprolactinemia was detected in 4% (7 of 171) of infertile men. In seven patients with excessive serum prolactin concentrations, the clinical manifestations were infertility, hypogonadism, impotence, and galactorrhea and the etiologic factors were pituitary adenoma, hypothalamic dysfunction, drug use, and idiopathic. The testes and prostate were small or normal and the semen analysis revealed low semen volume, normal or low sperm count, and normal or impaired sperm motility. The testicular biopsy showed normally preserved seminiferous tubules with normal or decreased spermatogenesis and damaged or fibrotic seminiferous tubules among normal ones. Patients with hyperprolactinemia were investigated by sellar polytomography, visual field examinations, and hormone assays. Treatment with bromocriptine (Parlodel) gave satisfactory results in all patients. The use of bromocriptine with human menopausal gonadotropin and human chorionic gonadotropin was beneficial in treating hypogonadotropic hypogonadism with hyperprolactinemia.
