Answer to Question 1
Correct Answer: 1
Most problems with erection are the result of a disease (with a three-times greater incidence in men with diabetes mellitus), injury, or chemical substances (such as prescribed medications, alcohol, nicotine, cocaine, or marijuana) that affect nerve conduction or hormone levels or decrease blood flow in the penis. Marital status, employment status, and educational level are not associated with an inability to sustain an erection.
