Can Smoking Cause Erectile Dysfunction?

Yes—smoking is a proven cause of erectile dysfunction. It narrows blood vessels, damages tissue lining, and reduces nitric oxide—all of which are needed for an erection. If you smoke, your penis suffers silently.

How Smoking Affects Erections

• Reduces blood flow to the penis
• Weakens smooth muscle function
• Increases risk of vascular ED

Is the Damage Reversible?

If you quit early, yes. Studies show improved erection quality within 1–3 months of quitting smoking—especially when combined with ED meds.
