The purpose of this study to perform a randomized, sham controlled analysis of the effectiveness of both fSWT and rWT in the relief of erectile dysfunction and chronic pelvic pain syndrome.

After being informed about the study and potential risks, all patients giving written informed consent will undergo screening to determine eligibility for study entry. Participants who meet eligibility requirements will be randomized in a double blind manner (participant and investigator) to each treatment arm depending on their primary complaint. Participants with erectile dysfunction will be randomized 2:2:1 to either fSWT, rWT or sham therapy. Patients with chronic pelvic pain syndrome will be randomized 1:1 to either fSWT with pelvic floor physical therapy (PFPT) or PFPT with sham treatment.
