Background:
Erectile dysfunction is associated with cardiovascular risk factors (e.g. hypertension, smoking, dyslipidemia and diabetes) and is more common in patients with cardiovascular disease. We therefore assessed the prevalence of two predictors of vascular events, fibrinogen and lipoprotein-a, in patients with and without erectile dysfunction.
Methods:
Men with erectile dysfunction (48 non-smokers, 48 smokers), aged 45-70 years, were compared with controls (21 non-smokers, 21 smokers) with normal erectile function and no known pathology.
Results:
Serum total cholesterol was significantly higher in non-smokers with erectile dysfunction compared to both control non-smokers and erectile dysfunction smokers. Men with erectile dysfunction who smoked had a significantly higher plasma fibrinogen level than control smokers. Similarly, men with erectile dysfunction, who did not smoke had higher levels of plasma fibrinogen compared to both smokers and non-smokers without erectile dysfunction. No significant difference in serum lipoprotein-a values was found.
Conclusions:
These findings support the concept that cardiovascular risk factors are predictors of erectile dysfunction and that this may be another manifestation of vascular disease.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
