Prostatic Cancer, Hypogonadism, and Insulin ResistanceA case reportFrom the Second Department of Internal Medicine, NIMTS Hospital, Athens, Greece Address correspondence to John A. Kiayias, MD, Agisilaou 72, Sparti 23100, Greece. E-mail: jkiayias@endo.gr
A 47-year-old Greek diabetic man presented with erectile dysfunction and a decrease in sexual desire. The patient had type 2 diabetes for the previous 8 years and was on treatment with rosiglitazone and metformin with strict glycemic control (HbA1c 5.8%). No symptoms or signs of neuropathy were present. Hypogonadotrophic hypogonadism was found. His plasma testosterone level was very low (100 ng/dl [reference range 3001,000]) and there was no luetinizing hormone response to luetinizing hormonereleasing hormone (LHRH) test. Further work-up with a magnetic resonance imaging scan and hypophyseal function tests did not reveal any space-occupying lesions of the hypothalamic pituitary site.
The process led to the diagnosis of idiopathic hypogonadotropic hypogonadism. On further work-up, the patient was found to have a prostatic carcinoma.
