Diabetes can cause circulatory problems, which can increase the risk of erectile dysfunction in men.
In the new analysis, study participants who took Viagra reported significant improvement in their ability to achieve and maintain an erection versus those men treated with an inactive placebo pill. While treatment responses were lower for diabetic patients compared with nondiabetic men, they were higher than that seen in previous studies. Viagra significantly improved erectile function treatment for men with type 1 diabetes, and efficacy was comparable to that reported by men with type 2 diabetes. Type 1 diabetes is an autoimmune disease that usually develops in children and young adults, and leads to a life-long need for insulin injections. Type 2 diabetes usually develops in adulthood and can often be controlled with diet, exercise and oral medication.
