• Taking Viagra, Levitra or Cialis without treating the original problem may improve sexual performance, but don't ignore an underlying issue by just taking pills to treat the symptom of another health issue.

• Getting proper treatment for the underlying cause of erectile dysfunction may help you prevent related health problems and improve sexual performance. A number of conditions can cause or worsen erectile dysfunction:

• Heart disease. In some cases, erectile dysfunction is the first sign of serious heart or blood vessel problems such as hardened arteries (atherosclerosis).

• Diabetes. Over time, uncontrolled diabetes can damage blood vessels and nerves, making it more difficult to get or keep an erection.

• Psychological issues. Depression or anxiety can cause sexual problems and often requires psychological counseling or medications to get better.

• Being overweight. Being overweight or obese can cause or worsen erectile dysfunction because of hormonal changes and related cardiovascular issues. Increased physical activity and losing weight can improve your overall health and sexual function.

• Low testosterone. Men who have low testosterone levels (hypogonadism) may need testosterone replacement therapy to increase sex drive and sexual performance.

• Lifestyle choices. Unhealthy habits such as drinking too much alcohol, smoking, using illegal drugs and a sedentary lifestyle can all worsen erectile dysfunction.
