Investigating the Effect of Exosome Derived From Human Fetal Umbilical Cord Mesanchymal Cells as Complimintary Treatment in Moderate to Severe Erectile Dysfunction
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.
