I now have solid, textbook-grounded information to give you a thorough, practical answer.
Erectile Dysfunction (ED) at Age 56 - What You Should Know & Do
What Is ED?
Erectile dysfunction is defined as the inability to achieve and/or maintain an erection sufficient for satisfactory sexual performance. It is very common - affecting about 6% of men aged 50-59, rising to 17% by age 60-69. So at 56, you are not alone, and this is absolutely treatable.

Why Does It Happen? (Common Causes)
Your doctor will look for these underlying causes:
| Category | Examples |
|---|
| Cardiovascular | High blood pressure, coronary artery disease, high cholesterol |
| Metabolic | Diabetes (very strong link), obesity |
| Hormonal | Low testosterone (hypogonadism), thyroid problems |
| Neurological | Peripheral neuropathy, prior pelvic surgery |
| Psychological | Depression, anxiety, relationship stress |
| Medications | Beta-blockers, thiazide diuretics, antidepressants (SSRIs), antipsychotics, spironolactone, finasteride |
| Lifestyle | Smoking, alcohol, sedentary lifestyle |
Important: Men with ED often have underlying cardiovascular disease - sometimes before heart symptoms appear. ED and heart disease share the same risk factors. As the textbook says: "What is bad for the heart is bad for the penis." Getting a cardiac risk assessment is important.
Step 1: See a Doctor for Proper Evaluation
Before any treatment, your doctor should assess:
- Medical history - heart disease, diabetes, blood pressure, surgical history
- Medication review - many common drugs cause ED (see table above)
- Physical exam - blood pressure, genital and prostate exam, peripheral pulses
- Blood tests:
- Fasting blood sugar and HbA1c (diabetes)
- Lipid panel (cholesterol)
- Testosterone level (total and free)
- Kidney function, liver function
- PSA (prostate)
- Thyroid (TSH)
Step 2: Treatments Available
First-Line: PDE5 Inhibitors (Oral Pills) - Most Effective
These are the standard first-choice treatment and work for most men:
| Drug | Brand Name | How to Use |
|---|
| Sildenafil | Viagra | 30-60 min before sex, as needed |
| Tadalafil | Cialis | Daily low dose OR as needed (lasts 36 hrs) |
| Vardenafil | Levitra | 30-60 min before sex |
These drugs work by increasing blood flow to the penis (they block PDE5, which allows cGMP to build up, relaxing the smooth muscle and enabling erection). They do not cause an automatic erection - you still need sexual stimulation.
Important warnings:
- Do NOT take with nitrates (nitroglycerin, isosorbide) - dangerous blood pressure drop
- Talk to your doctor if you have heart disease before starting
If Testosterone Is Low
If your testosterone comes back below 300 ng/dL, testosterone replacement therapy can help. Options include:
- Testosterone gel applied daily to skin
- Intramuscular injections every 2-4 weeks
- Testosterone patches
- Subcutaneous pellets every 3-6 months
Second-Line Treatments (If Pills Don't Work)
- Alprostadil (PGE1) - injected directly into the penis (intracavernosal) or inserted as a pellet into the urethra. Very effective even when pills fail.
- Vacuum Erection Device (VED) - a pump device that draws blood into the penis. Works for nearly any cause of ED.
Third-Line
- Penile implant (prosthesis) - surgical option, used only when all other treatments have failed. High satisfaction rates.
Step 3: Lifestyle Changes That Help
These actually work and can significantly improve erections:
- Lose weight if overweight - weight loss alone can restore erectile function in obese men
- Exercise regularly - improves blood flow and testosterone
- Stop smoking - smoking damages penile blood vessels directly
- Reduce alcohol - alcohol is a depressant and impairs erection
- Manage stress and sleep - psychological factors are real contributors
- Control blood sugar, blood pressure, and cholesterol
Step 4: Address Psychological Factors
If there is performance anxiety, relationship stress, or depression involved, psychosexual counseling or sex therapy can help - especially when combined with medication. Men receiving group therapy plus sildenafil showed significantly better outcomes than sildenafil alone.
What to Do Right Now - Action Plan
- Book an appointment with your doctor (GP or urologist) - do not self-treat
- Get blood tests - testosterone, blood sugar, lipids, kidney/liver function
- List all your current medications - some may be causing this
- Start lifestyle changes today - exercise, diet, quit smoking
- Discuss PDE5 inhibitors with your doctor - sildenafil or tadalafil are safe for most men
- If you have cardiovascular symptoms - get those evaluated first
