Stem cell therapy shows promise for severe erectile dysfunction
NCT ID NCT07245875
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether an injection of umbilical cord stem cell secretome is safe and can improve erections in 12 men with severe erectile dysfunction that did not respond to sildenafil (Viagra). All participants had type 2 diabetes. The treatment was given as a single injection, and the researchers monitored for side effects like pain or bleeding and measured erection hardness and questionnaire scores. The goal was to see if this approach could ease symptoms when standard medication fails.
