Which of the following is NOT a common cause of organic erectile dysfunction?

Organic erectile dysfunction is typically attributed to physical or physiological factors rather than psychological ones. The conditions that commonly lead to organic erectile dysfunction include diabetes mellitus, atherosclerosis, and stroke, all of which affect blood flow and nerve function essential for achieving and maintaining an erection.

Diabetes mellitus can lead to nerve damage (neuropathy) and blood flow issues, both of which directly impact erectile function. Atherosclerosis refers to the buildup of plaque in the arteries, which can restrict blood flow to the penis and contribute to erectile difficulties. Stroke can disrupt the nerve pathways involved in erections, resulting in organic causes of erectile dysfunction.

In contrast, depression is primarily considered a psychological issue, which can indeed affect sexual function, but it is not classified under organic erectile dysfunction. Psychological factors like stress, anxiety, and mood disorders can influence sexual performance but do not stem from underlying physical or organic conditions. Therefore, identifying depression as the option that does not align with the organic causes of erectile dysfunction is accurate.
