title: Successful treatment of male infertility due to hypogonadotropic hypogonadism--report of three cases.
abstract: Exogenous gonadotropins or pulsatile gonadotropin-releasing hormone is now most commonly used to treat male infertility due to hypogonadotropic hypogonadism. We report three cases of hypogonadotropic hypogonadism with variable etiologies and presentations who were successfully treated with exogenous gonadotropins and/or testosterone for their infertility. The diagnosis and clinical presentations of these three patients are summarized as follows. The first patient was a case of Kallmann's syndrome presented with short stature, infantile genitalia and anosmia. The second patient was a case of idiopathic hypogonadotropic hypogonadism presented with small genitalia and impotence. The third patient was a case of acquired hypogonadotropic hypogonadism due to pituitary adenoma presented with impotence, cold intolerance and visual field defect. After adequate therapy with human chorionic gonadotropin, human menopausal gonadotropin and/or testosterone, the secondary male characteristics of these three patients improved and the fertility were all restored.
