PRP Exosomes Therapy for Erectile Dysfunction

"All subjects will receive three sessions of PRP-derived exosomes injection with 21± 3 days treatment interval.The patient will be positioned supine.~A ¼-inch Penrose drain will be used as a tourniquet by placing it at the base of the penis and maintaining it in place under tension by a sterile clamp. We will obtain 10 mL of PRP per patient, but one of them will be used for platelet cell count analysis. A total 9 mL of the PRP-derived exosomes will be infused steadily over a 2 minutes period - 4.5 mL each into the right and left corpus cavernosum. The infusion will be performed at this slow speed - each side over 2 minutes of infusion - to minimize injury to the exosomes and cells. Following administration, compression of the penis will be achieved with a clenched fist for 20 minutes. At 20 minutes, the tourniquet will be removed, and a compressive dressing will be placed around the penile shaft. The patient will be instructed to remove the compression bandage in 4 hours"
