| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| To determine whether, in men with untreated ED but no other cardiovascular risk factors, not currently receiving lipid lowering therapy, treatment with Simvastatin improves erectile function. |  | 
| E.2.2 | Secondary objectives of the trial | 
| To determine whether: 1) Any improvement in erectile function leads to an improvement in sexual health related quality of life.
 2) Any improvement in erectile function is related to: i) reduction in LDL cholesterol;  ii) improvement in endothelial function (in sub-study).
 3) Treatment of ED with Simvastatin is cost effective

| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| Erectile dysfunction (ED) measured by the 5 item version of the International Index of Erectile Function (IIEF-5) This is a validated self-administered questionnaire requiring those completing it to have attempted vaginal sexual intercourse in the preceding four weeks. Each item scores 1 to 5 giving a total from 5 to 25. A score > 21 denotes no ED, 21-17 mild ED, 16-12 moderate ED and 7-5 severe ED. Those with scores < 22 are eligible unless receiving treatment for ED.
