The cardiovascular connection
Erections require healthy blood vessels. The arteries supplying the penis are roughly 1–2 mm in diameter — significantly smaller than the coronary arteries (3–4 mm). When systemic atherosclerosis develops, smaller vessels become clinically affected first.
This is why ED often precedes a major cardiovascular event by 3–5 years in men under 60.[1] The Princeton III Consensus Conference, an international expert panel, formally classified ED as an independent cardiovascular risk factor that warrants vascular assessment.[2]
What ED can signal beyond vascular disease
ED has many possible underlying contributors, and the right evaluation considers all of them:
- Cardiovascular — endothelial dysfunction, atherosclerosis
- Endocrine — low testosterone, thyroid dysfunction, prolactin elevation, diabetes
- Neurological — diabetic neuropathy, post-surgical nerve damage
- Medication-related — antidepressants, beta blockers, finasteride
- Psychological — performance anxiety, depression, relationship factors
- Lifestyle — sleep apnea, obesity, sedentary patterns, alcohol use
Why prescribing a PDE5 inhibitor without workup is a missed opportunity
Tadalafil and sildenafil work for many men. But prescribing them without evaluating contributing factors means missing the chance to identify — and address — what's actually driving the problem.
A 2018 meta-analysis of over 100,000 men showed that ED was associated with a 44% increased risk of subsequent cardiovascular events, even after adjusting for traditional risk factors.[3] Treating ED in isolation can mask a developing cardiovascular trajectory that would be worth catching early.
What a proper ED evaluation looks like
A thoughtful clinical evaluation pairs ED treatment with a screening workup: a full lipid panel including ApoB, fasting glucose and A1C, blood pressure, full hormone panel (total/free testosterone, SHBG, prolactin, TSH), and a review of medications. Lifestyle factors — sleep, weight, exercise, alcohol — get addressed in parallel.
This comprehensive approach lets the clinician treat the immediate symptom while also identifying upstream factors. Many men see ED improve as their underlying health improves — and that improvement protects them from much more serious events down the road.
What to do with this information
If you are experiencing ED, the right approach pairs effective immediate treatment with a thorough workup of what may be contributing. A physician evaluation including comprehensive bloodwork is the foundation of that conversation.
