How Does Smoking Affect Erectile Function?
Is There a Relationship Between Smoking and Erectile Dysfunction?
Yes.
Smoking is one of the most important preventable risk factors for erectile dysfunction (ED) in men.
Today, it is well established that smoking affects not only the lungs but also the vascular system. Because healthy blood vessels are essential for normal erectile function, smoking can have a significant impact on male sexual health.
The EAU 2026 Guidelines identify smoking as an important cardiovascular risk factor associated with erectile dysfunction.
Why Are Blood Vessels So Important for a Healthy Erection?
A normal erection depends on the ability of penile blood vessels to expand during sexual stimulation.
This process allows:
Increased blood flow to the penis,
Expansion of erectile tissues,
Development and maintenance of penile rigidity.
Any condition that impairs vascular health may negatively affect erectile quality.
How Does Smoking Damage Blood Vessels?
Cigarette smoke contains numerous chemicals that can damage the inner lining of blood vessels.
This may result in:
Reduced ability of blood vessels to dilate,
Accelerated atherosclerosis,
Impaired blood circulation,
Structural changes in the vascular wall.
As a consequence, less blood may reach the penile tissues, leading to reduced erectile quality.
Why Are Penile Arteries Particularly Vulnerable?
The arteries supplying the penis are among the smallest arteries in the body.
Because of their small size, early vascular damage often becomes apparent in the penile circulation before symptoms develop elsewhere.
For some men, a decline in erectile quality may be the first noticeable consequence of smoking-related vascular injury.
Is Erectile Dysfunction More Common in Smokers?
Yes.
Studies have consistently shown that erectile dysfunction occurs more frequently in men who smoke.
The risk increases with:
The number of cigarettes smoked per day,
The duration of smoking,
The presence of additional cardiovascular risk factors.
Can Passive Smoking Also Have an Effect?
Long-term exposure to cigarette smoke may also negatively affect vascular health.
Although passive smoking is generally less harmful than active smoking, it is still associated with adverse cardiovascular effects and may contribute to vascular dysfunction.
Does Smoking Affect More Than Blood Vessels?
Yes.
The effects of smoking are not limited to the vascular system.
Smoking may:
Impair overall cardiovascular health,
Reduce physical performance,
Be associated with metabolic disorders,
Contribute to the development of multiple risk factors simultaneously.
For this reason, its impact on erectile function is often multifactorial.
Can Erectile Function Improve After Quitting Smoking?
Quitting smoking is one of the most important s
