Why Diabetes Causes Erectile Dysfunction
Erectile dysfunction affects approximately 50–75% of men with diabetes — a significantly higher rate than the general population. High blood glucose damages the endothelium (blood vessel lining), reducing nitric oxide production and impairing blood flow. Diabetic neuropathy also damages the nerves responsible for erectile function, and diabetes-related testosterone decline contributes to decreased libido and erection quality.
How PRP Therapy Addresses Diabetic ED
The P-Shot addresses two of the primary mechanisms of diabetic ED: it promotes angiogenesis (new blood vessel formation) in damaged penile vasculature, and it delivers growth factors that support peripheral nerve repair. Clinical studies in diabetic patients have shown meaningful improvements in erectile function scores following PRP treatment, suggesting that PRP can overcome some of the damage caused by diabetes.
Clinical Evidence in Diabetic Patients
A 2019 study specifically examining PRP for ED in type 2 diabetic patients found a clinically significant improvement in erectile function scores in 58% of participants — lower than the general population average but still meaningful. A 2021 systematic review concluded that PRP is a promising option for diabetic ED, particularly when combined with other treatments such as VED or low-dose PDE5 inhibitors.
What Diabetic Patients Should Expect
Diabetic patients typically need to have realistic expectations about the extent of improvement. Blood glucose control at the time of treatment significantly influences outcomes — well-controlled diabetes (HbA1c below 7.5%) is associated with better PRP response. Multiple treatments may be needed. Our doctors will assess your diabetes management as part of the pre-treatment consultation.
