This review covers erectile dysfunction (ED) in men with metabolic syndrome. Men suffering from metabolic syndrome, and all its components, are at increased risk of ED. Men with ED should be metabolically screened with BMI, waist circumference, blood pressure, HbA1c and lipids. Components of the metabolic syndrome should be well-controlled as first step in treating ED using lifestyle changes and pharmaceutical therapies. Symptomatic treatments include phosphodiesterase type 5 inhibitors, penile injections, intraurethral medication, vacuum pumps and penile implants.
