A prospective study by researchers from the Harvard School of Public Health (HSPH) has found that obesity and smoking are strongly associated with a greater risk of erectile dysfunction (ED). Meanwhile, regular physical activity appeared to have a significant impact on lowering the risk of Erectile Dysfunction. This is the first large-scale prospective study to examine the links between Erectile Dysfunction and smoking, obesity, alcohol and a sedentary lifestyle. The study will appear in the July 2006 issue of The Journal of Urology.

The researchers, led by Constance Bacon, a former post-doctoral fellow at HSPH, and Eric Rimm, associate professor of epidemiology and nutrition at HSPH, surveyed 22,086 healthy subjects between the ages of 40 and 75 from the Health Professionals Follow-up Study who reported good or very good erectile function and no major chronic disease before 1986. Among the participants, 17.7 percent (3,905) reported new onset of Erectile Dysfunction between 1986 and 2000. The researchers adjusted the results to take into account those with and without prostate cancer during the follow-up period, since prostate cancer treatments, such as radiation or surgery, may lead to Erectile Disfunction.

Levitra, Cialis and Viagra are the first three US Food FDA approved erectile dysfunction drugs.
