The efficacy and safety of 4 different session frequency protocols will be compared.', 'detailedDescription': 'This is a randomized, 4 parallel arms, clinical trial with an 18-month recruitment period. All patients will be PDE5I users/responders. After 1 month wash-out period, ED patients will be screened, in order to randomize 96 men with vasculogenic ED, an International Index of Erectile Function ED (IIEF-ED) domain score between 6-25 and abnormal penile triplex-based hemodynamic parameters (peak flow velocity \\<35cm/sec) in the last 6 months. Additionally, they will be asked to complete the SEP diaries. Patients will be randomized to receive shockwave treatments (12 sessions for all subjects), either twice a week (total of 6 weeks) or three times a week (total of 4 weeks) at energy level 4 or 7, without treatment interval.\n\nStudy visits and duration\n\nVisit 1 (day 0): the basic work-up will take place, including medical and sexual history, as well as necessary lab tests, if needed. One month wash-out period will follow. During this period, all subjects will be asked to avoid any drug related to ED (PDE5i) and have at least 2-4 attempts for intercourse. Furthermore, patients will undergo triplex ultrasonography, unless they have already done so in the last 6 months.Also penile dimensions in both flaccid and erect state will be measured.\n\nVisit 2 (day 28 + 3 days): all patients will complete the IIEF-ED domain and will be randomized to one of the four parallel study groups, using an online program. Groups A and C will receive treatment twice per week, at energy level 4 and 7 respectively. Groups B and D will receive treatment three times per week, at energy level 4 and 7 respectively. PDE5i use is prohibited throughout the study.\n\nTreatment Visits: There will be 12 active treatment visits for all 4 Groups. Patients will receive LI-ESWT, according to the study protocol. Interval between 2 treatments will be 3+1 days for Groups A and C (twice/week) whereas 1+1 day for Groups B and D (three times/week). At visit 6 and 12 a penile ultrasonography will be conducted in order to check for potential adverse events related to the treatment.\n\nFollow-up visits 1 - 3 (4, 12 ,24 and 48 weeks post treatment): Patients will complete the IIEF-ED questionnaire and return the completed SEP diaries for the last 4 weeks prior to every visit. Visit data will also be recorded (protocol compliance, adverse events). At Week 12, triplex will be performed by the standard protocol. For Week 4 there is a + 3 days visit window, whereas for weeks 12, 24 and 48 there is a + 2 weeks visit window.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.
