Summary
This phase 2 trial tested a single injection of stem cells from the patient's own bone marrow to treat erectile dysfunction after prostate cancer surgery. Fifty-four men who had surgery at least a year prior and had stable PSA levels received the injection. The study measured changes in erectile function using a standard questionnaire, aiming to see if the stem cells could safely improve sexual function.
