Is there a link between high cholesterol and erectile dysfunction?
High cholesterol and erectile dysfunction are connected through the health of your blood vessels. Cholesterol buildup can narrow arteries, reducing blood flow to the penis. This process is part of atherosclerosis, which affects the whole body but often shows up first in sexual function. Doctors view this as a warning sign that heart and vessel health is declining.
What the research says
Epidemiological studies show that elevated serum cholesterol and reduced high density lipoprotein (HDL) cholesterol levels are associated with an increased risk of erectile dysfunction 6. This link exists because erectile function relies on healthy blood flow, and high cholesterol contributes to the plaque buildup that restricts that flow. In aging men with risk factors like hypercholesterolemia, a higher prevalence of erectile dysfunction reflects systemic vasculopathy that often first presents as abnormal erectile function 5.
Research suggests that dyslipidemia is strongly associated with obesity and atherosclerosis, and is increasingly recognized as an independent risk factor for erectile dysfunction 3. Dyslipidemia contributes to erectile dysfunction through multiple interconnected pathways, including vascular dysfunction, neural impairment, oxidative stress, inflammation, and endocrine alterations 3. These mechanisms may increase susceptibility to erectile dysfunction in affected patients.
A 2026 cross-sectional study using data from the National Health and Nutrition Examination Survey found a strong negative association between the ratio of non-high-density lipoprotein cholesterol to HDL cholesterol and erectile dysfunction occurrence 7. For every unit increase in this specific ratio, the prevalence of erectile dysfunction fell by 9% in the fully adjusted model 7. This suggests that the balance of different cholesterol types matters for sexual health, even if total cholesterol levels are not the only factor.
What to ask your doctor
- How does my current cholesterol profile affect my risk for erectile dysfunction?
- Could improving my lipid levels help prevent or improve my sexual function?
- Are there specific cholesterol ratios, like the non-HDL to HDL ratio, that I should monitor?
- What lifestyle changes can I make to address both my cholesterol and my erectile function?
