Association of Plasma Atherogenic Index with Erectile Dysfunction: Cross-Sectional Study

Overview

This cross-sectional study investigated the relationship between lipid profiles, specifically the Atherogenic Index of Plasma (AIP), and erectile dysfunction (ED) in adult men. Findings indicated no significant differences in AIP or other lipid parameters between men with and without ED, suggesting limited association in this cohort.

Background

Erectile dysfunction (ED) is a prevalent condition linked to endothelial dysfunction and atherosclerosis, sharing risk factors with coronary artery disease. The arterial size hypothesis posits that penile arteries are affected by atherosclerosis earlier than larger arteries, potentially making ED an early marker of systemic vascular disease. The Atherogenic Index of Plasma (AIP), reflecting the balance of triglycerides and HDL cholesterol, is a biochemical marker associated with atherosclerotic risk. This study aimed to explore whether AIP and other lipid indices differ between men with ED and those without.

Data Highlights

Key Findings

• No significant differences in AIP values were observed between men with ED and men without ED.
• Body mass index (BMI) was comparable across all ED severity subgroups and men without ED.
• Lipid parameters including total cholesterol, triglycerides, and HDL cholesterol did not differ significantly between groups.
• The study excluded patients with confounding conditions or medications affecting erectile function to isolate the association with lipid indices.
• ED severity stratification based on IIEF-5 scores did not reveal correlations with atherogenic indices.

Clinical Implications

These findings suggest that AIP and conventional lipid profiles may have limited utility as biomarkers for erectile dysfunction in the absence of overt cardiovascular disease. Clinicians should consider multifactorial etiologies of ED and not rely solely on atherogenic indices for risk stratification. Comprehensive cardiovascular risk assessment remains essential in men presenting with ED.

Conclusion

In this observational study, plasma atherogenic indices including AIP did not differ significantly between men with and without erectile dysfunction, indicating that these lipid markers alone may not be predictive of ED status. Further research is warranted to clarify the role of lipid metabolism in ED pathophysiology.
