Abstract We investigated the effects of Antep pistachio on International Index of Erectile Function (IIEF) scores, penile color Doppler ultrasound (PCDU) parameters and serum lipid levels in patients with ED. A total of 17 married male patients with ED for at least 12 months were included in this prospective study. Patients were put on a 100 g pistachio nuts diet for 3 weeks. IIEF and PCDU were evaluated before and after the pistachio diet. In addition, plasma total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL) and triglyceride were measured before and after dietary modifications from all subjects. Mean IIEF-15. | Pistachio Diet Improves Erectile Function Parameters and Serum Lipid Profiles in Patients with ED Abstract We investigated the effects of Antep pistachio on International Index of Erectile Function IIEF scores penile color Doppler ultrasound PCDU parameters and serum lipid levels in patients with ED. A total of 17 married male patients with ED for at least 12 months were included in this prospective study. Patients were put on a 100 g pistachio nuts diet for 3 weeks. IIEF and PCDU were evaluated before and after the pistachio diet. In addition plasma total cholesterol TC low-density lipoprotein LDL high-density lipoprotein HDL and triglyceride were measured before and after dietary modifications from all subjects. Mean IIEF-15 score was 36 before the diet and after the diet P . Similarly an increase in all five domains of IIEF was observed after the diet P . Mean peak systolic velocity values before and after the pistachio diet were and cm s-1 respectively P . After the pistachio diet TC and LDL levels decreased significantly whereas HDL level increased P and respectively . We demonstrated that a pistachio diet improved IIEF scores and PCDU parameters without any associated side effects in patients with ED. Furthermore the lipid parameters showed statistically significant improvements after this diet. Introduction Penile erection is a hemodynamic process involving increased arterial inflow and restricted venous outflow coordinated with corpus cavernosum and penile arterial smooth muscle relaxation. Any problem in this mechanism results in ED and its etiology is generally multifactorial. Diabetes hypertension high serum cholesterol level peripheral vascular disease and cardiac problems are significantly found together with vascular reasons predominate in the etiology of ED and it frequently appears along with atherosclerosis. It is known that atherosclerotic lesions prevent blood flow .
