Umbilical Cord Mesenchymal Stem Cell Secretome in Severe Erectile Dysfunction Non-responsive to Sildenafil

"UC-MSC secretome was obtained from UC-MSC cultures with 80% confluence in serum-free medium after 24 hours of incubation The VEGF level in the secretome given was 1400 pg/ml.~The intervention was the administration of 0.5 mL/site of secretome injection injected intra-cavernous to all subjects using a 22-gauge needle according to a sterile protocol. The same volume was given at bilateral sites of the penile shaft. The intra-cavernous injection sites were in the right and left dorsolateral regions of the penis. After the intervention, tolerability was assessed by observing and questioning the subjects regarding pain during injection."
