[Metabolic syndrome and hormone profile in patients with erectile dysfunction]

To demonstrate the existence of relation between metabolic syndrome and erectile dysfunction and to analyze the hormone profile of these patients regarding a healthy population group.

A case-control study was designed with 65 men divided into 2 groups according to presence or non-presence of erectile dysfunction. Group A was made up of 37 men with erectile dysfunction and group B by 28 healthy men without erectile dysfunction. Ages ranged from 40 to 65 years. The presence of metabolic syndrome according to the ATPIII definition, performance of physical exercise, smoking habit, body mass index and complete hormone profile including testosterone -total, free and bioavailability, were studied.

Greater presence of metabolic syndrome was detected among men of Group A (72.9%) versus those of group B (17.8%) (p=0.0001). Among the parameters that make up the metabolic syndrome, there are differences between both groups in systolic and diastolic blood pressure, fast blood sugar and abdominal circumference, all these differences being significant. After performing multivariate analysis between the metabolic syndrome and erectile dysfunction adjusted for age, BMI, International Index for Erectile Function (IIEF), physical exercise and smoking habit, we have observed an independent significant relation between the metabolic syndrome and erectile dysfunction. We have not found differences between both groups in any hormone parameter.

A relationship is found between metabolic syndrome and erectile dysfunction. Thus, it seems recommendable to perform the metabolic profile and cardiovascular risk study in these patients.
