Erectile dysfunction and lower androgenicity in type 1 diabetic patients

OBJECTIVE: To analyse the clinical characteristics and relevant hormonal profile in type 1 diabetic patients with and without ED. MATERIAL AND METHODS: Fifty one type 1 diabetic patients were studied. ED was assessed by direct interview. Chronic diabetic complications, smoking and alcohol status as well as current use of medications were recorded. Hormonal profile consisted of plasma LH, FSH, prolactin, androstenedione (Delta(4)), dehydroepiandrosterone (DHEA), DHEA-sulfate (DHEA-S), free testosterone (FT), estradiol (E(2)), sex hormone binding globulin (SHBG), dihydrotestosterone (DHT), cortisol, TSH and free thyroxine (FT(4)).RESULTS: ED was present in 24 patients (47%) (group 1), who were older (P<0.001), had a longer diabetes duration (P<0.001) and a higher systolic blood pressure (P=0.017) when compared to the subjects who did not complain (group 2). ED was positively correlated to all diabetes-related complications (P<0.02). Antidepressive drug(s) were more frequent in group 1 (P=0.007), as well as prokinetics (P=0.043) and ACE-inhibitors (P=0.010). HbA(1)c was comparable. Patients with ED had lower levels of Delta(4) (P=0.003), DHEA (P
