International Index of Erectile Function (IIEF-EF) QuestionnairePrimary· 7 months
IIEF is a 15 item self-administered questionnaire assessing erectile dysfunction and treatment outcomes. Total IIEF score range from 5-25 with scores classifying erectile dysfunction (ED) as: severe (5-7); moderate (8-11); mild to moderate (12-16); mild (17-21) and no ED (22-25). The questionnaire will be assessed at baseline (before 1 month washout prior to treatment initiation), 1 month follow up (at 2 months), 3 month follow up (at 4 months) and 6 months follow up (at 7 months).

Erection Hardness Score (EHS)Secondary· 7 months
EHS rates the hardness of erection on a scale of 1-4 assessed at baseline (before 1 month washout prior to treatment initiation), 1 month follow up (at 2 months), 3 month follow up (at 4 months) and 6 months follow up (at 7 months). A score of 0 = penis does not enlarge; 1 = penis is larger but not hard; 2 = penis is hard but not hard enough for penetration; 3 = penis is hard enough for penetration but not completely hard; 4 = penis is completely hard and fully rigid.

Sexual Encounter Profile (SEP)Secondary· 7 months
Sexual Encounter Profile (SEP) is a measure of efficacy of erectile dysfunction therapy. Improved responses to treatment will be reported as the percentage of participants that responds "yes" and non-improvement responses to treatment will be reported as the percentage of participants that responds "no".

Sponsor's own description
Renova- Erectile Dysfunction (ED) is a Linear Shockwaves (LISW) device which incorporates a unique shockwave transducer operable to deliver shockwaves to a treated region. Shockwaves are aimed at the left and right corpora cavernosa and the crura. The study is aimed at determining the safety and effectiveness of this new type LISW in the relief of erectile dysfunction.
HYPOTHESIS Alternate Hypothesis (HA): Active Treatment groups will show a \>2-point increase in the IIEF-EF score from baseline for mild erectile dysfunction, and \>5 points for moderate erectile dysfunction and will show significant change.
Null Hypothesis (HO): There is no difference from baseline and after-treatment in Treatment groups for alleviating erectile dysfunction measured using International Index of Erectile Function score (IIEF-EF).
Primary Efficacy Objective: To evaluate change of International Index of Erectile Function score Questionnaire score from baseline to follow-ups 1, 3 and 6 months' post treatment.
Secondary Objectives:To study sexual activity improvement leading to optimal penetration at follow-ups according to:
* SEP- Sexual Encounter Profile Questionnaire.
* GAQ- Global Assessment Questionnaire.
* EHS- Erection Hardness Score.
