The second Princeton consensus on sexual dysfunction and cardiac risk: new guidelines for sexual medicine. Jackson G, Rosen RC, Kloner RA, and Kostis JB. J Sex Med 2006;3:28–36. • The recognition of ED as a warning sign of silent vascular disease has led to the concept that a man with ED and no cardiac symptoms is a cardiac (or vascular) patient until proven otherwise. • Men with ED and other cardiovascular risk factors (e.g., obesity, sedentary lifestyle) should be counseled in lifestyle modification.
Cardiometabolic risk and female sexual health: The Princeton III summaryMiner M, Esposito K, Guay A, Montorsi P, and Goldstein I.

Smoking • Population-based cross-sectional study of 1,580 participants. • The IIEF-5 was used to assess erectile function. • Compared with never smokers, the odds of ED, adjusted for age, square of age, and CVD, were significantly higher among current smokers (odds ratio [OR] = 1.40; 95% confidence interval [CI] 1.02, 1.92). 2008 Chew K-K, Bremner A, Stuckey B, Earle C, and Jamrozik K.

Smoking • Ratshas a constant influx of smoke using a specially constructed device. 24 Sprague Dawley (SD) rats were randomly into two groups: an experimental group and a control group. 36rats for the chronic cigarette smoke exposure were randomly divided into three groups: a control group and two experimental groups. • Electrical field stimulation of the cavernosal nerve to assess the erectile function,. • Vasoconstrictor effects & the decrease in testosterone levels after chronic smoking had some effects on erectile function in rats.

Diabetes Support & Education (DSE)? Oral & written information about • Healthy food choices • Physical activity. Effects of weight loss intervention on erectile function in older men with type 2 diabetes in the look AHEAD trial. J Sex Med 2010;7:156–165.
Intensive lifestyle intervention (ILI)? • Body Weight :Detailed advice about how to reduce body weight • Diet: • 7 sessions with a nutritionist • Personal goal-setting • Self-monitoring (food diaries) through a series of monthly small-group sessions. • Exercise: Individual guidance • Behavioral and psychological counselingwas offered
Intensive lifestyle intervention (ILI) Diabetes support and education (DSE) • Greater improvement in EF (17.3 +/- 7.6 at baseline; 18.6 +/- 8.1 at 1 year) than in DSE (18.3 +/- 7.6 at baseline; 18.4 +/- 8.0 at 1 year); P = 0.06
