Erectile dysfunction (ED) is a common complication of diabetes that affects up to 75% of diabetic men at some point in their lives. The combination of nerve damage (neuropathy), poor blood circulation, and hormonal changes makes ED particularly challenging for men with diabetes. However, with proper treatment, most diabetic men can regain sexual function.
This comprehensive guide examines the most effective treatments for ED in diabetic men, from medications and devices to lifestyle changes and surgical options.
Understanding ED in Diabetic Men
How Diabetes Causes ED
Diabetes contributes to erectile dysfunction through several mechanisms:
- Vascular damage – High blood sugar damages blood vessels, reducing blood flow to the penis
- Nerve damage – Diabetic neuropathy impairs the nerve signals needed for erection
- Hormonal changes – Diabetes can lower testosterone levels
- Psychological factors – The stress of managing diabetes may contribute to ED
Differences From Non-Diabetic ED
ED in diabetic men tends to:
- Develop earlier (often 10-15 years sooner than non-diabetics)
- Be more severe
- Be less responsive to oral medications
- Require combination treatments
Medical Treatments for Diabetic ED
Oral Medications (PDE5 Inhibitors)
How they work:
- Enhance the effects of nitric oxide
- Improve blood flow to the penis
Common options:
- Sildenafil (Viagra)
- Tadalafil (Cialis)
- Vardenafil (Levitra)
- Avanafil (Stendra)
Effectiveness in diabetics:
- Works for about 50-60% of diabetic men

- Rarely, vision changes
Penile Injections
How they work:
- Medications injected directly into the penis
- Cause blood vessels to dilate
Common medications:

- Erections last 30-60 minutes
Side effects:
- Pain at injection site

Side effects:
- Burning sensation
- Dizziness
- Minor bleeding
Vacuum Erection Devices
