What this early signal can reveal and what to do next

4 Reasons ED Deserves a Closer Look at Your Heart Health

Erections depend on blood flow. Here is why that matters for your heart and what you can do about it.

01

Erections Depend on Healthy Blood Flow

Blood Flow Shows Up Here First.


An erection depends on steady blood flow. When blood flow is impaired, erections can change. A persistent change can be a useful prompt to look at cardiovascular health, not only sexual performance.

02

Penile Arteries Are Smaller Than Carotid Arteries

Penile arteries are smaller than the arteries feeding the heart. The same vessel disease can affect blood flow there sooner. That is why a change in erections can draw attention to a bigger circulation problem.

03

The Same Vessel Problem Can Affect Both Places

Blood vessels need to relax and widen to deliver blood. When that function is impaired, it can affect the bedroom and the heart. The connection is one reason clinicians look beyond treating the immediate symptom.

04

ED Can Show Up Years Before a Cardiovascular Event

In some men, ED appears 2 to 5 years before symptoms of heart disease. In fact 50-70% of men with known carotid artery disease have also been reported to have ED.


It is an opportunity to check your risk sooner, not a countdown to a heart attack. New or persistent ED deserves a conversation with your clinician.

Supporting Your Circulation = Supporting Your Sexual Health

Erections depend on blood flow. So supporting the cardiovascular system that delivers that blood is worth thinking about—not just for the bedroom, but for your long-term health.

SUPPORT BLOOD FLOW

Erections rely on enough blood reaching the penis and staying there. Healthy circulation helps support that process.

CARE FOR YOUR ARTERIES

The same vascular system supplying your heart supplies the rest of your body. Supporting arterial health means thinking beyond sexual performance alone.

KNOW YOUR NUMBERS

Blood pressure, cholesterol, ApoB and other markers can help build a clearer picture of cardiovascular health. If something changes sexually, it may be worth looking at the bigger picture.
