Full description

Erectile dysfunction (ED) is an inability to provide adequate erection to initiate or maintain any sexual activity. The ED prevalence in adult males is approximately 20%. Cardiovascular diseases, diabetes mellitus(DM), chronic systemic diseases, smoking and obesity are among the aetiology of ED .In recent years, publications indicating that active inflammatory processes cause ED are increasing. In these studies where neutrophil- lymphocyte (NLR) and platelet-lymphocyte ratios (PLR) were used as signs of inflammation, a significant relationship was found between diseases with these proportions .Neutrophil-to-lymphocyte ratio (NLR) is a simple parameter to assess easily the inflammatory status of a subject. It has proven its usefulness in the stratification of mortality in major cardiac events , as a strong prognostic factor in several types of cancers , or as a predictor and a marker of inflammatory or infectious pathologies (such is pediatric appendicitis) and postoperative complications. Through enhanced production of cytokines and expression of cellular adhesion molecules, the dysfunctional endothelium promotes inflammation within the vascular wall and sets the stage for initiation and progression of atherosclerotic lesions in both penile vasculature and in peripheral and coronary blood vessels. It has been shown that patients with vasculogenic ED have increased inflammatory activation compared to subjects without ED.There are numerous studies suggesting that phosphodiesterase-5(PDE-5) inhibitors, which are the first-line therapy of ED, might be effective in reversing generalized endothelial dysfunction. Chronic treatment restores endothelium-dependent relaxations at various sites of the vascular tree, even up to one week after cessation of the treatment . Previous studies reported a chronic effect of sildenafil and tadalafil on endothelial function and pro-inflammatory markers/mediators including intercellular and vascular cell adhesion molecules-1 (ICAM-1 and VCAM-1, respectively), high sensitivity C-reactive protein (hsCRP), and interleukin-6
