Brief summary

The goal of this clinical trial is to Investigate the Effect of Injection of MSC-Derived Exosome on Patients with Erectile Dysfunction in overall healthy males, aged 18-70, with-out any severe active medical condition, with moderate to severe erectile dysfunction based on IIEF-5, and non-satisfactory response to other treatments (5PDEI). The main question it aims to answer is: • Is MSC-derived exosome safe and effective in treating patients with ED by improving IIEF-5 score? If there is a comparison group: Researchers will compare the intervention group (Exosome receiving group) with control group (placebo receiving group) to see if exosomes are safe and effective in treating male adult patients with moderate-sever ED. Participants will receive six weekly injections of normal saline or exosome (based on group), and will undergo necessarily follow up, and examinations and observation.

Detailed description

Secondary outcomes are the folllowing: EHS score length of erected penis lenght of flacid penis (pulled) peak systolic volume (via dupler sonography) end diastolic volume (via dupler sonography) any adverse effects of exosome

Interventions

Intervention group: patients in this group will be injected 5 ml of exosome in corpus cavernosa of each side (2.5 ml in each side at base of the penis). This will happen once a week, for 6 weeks. Inorder to prevent the injected substance from spreading systemically, a tourniquet will be placed at the base of the penis for 10 minute following injection.

Control group: these patients will recieve 5 ml of intracavernosal normal saline (2.5 ml in each side of penile base). This will happen once a week, for 6 weeks. Inorder to prevent the injected substance from spreading systemically, a tourniquet will be placed at the base of the penis for 10 minute following injection.
