Common Causes of ED (Physical & Psychological)

ED rarely has a single cause — it's usually some combination of physical and psychological factors.

Physical causes

Reduced blood flow, hormonal changes, certain medications, and conditions like diabetes or high blood pressure are among the most common physical contributors.

Psychological causes

Stress, anxiety (including performance anxiety specifically), depression, and relationship dynamics can all play a significant role, often independent of physical health.

Why the pattern matters

Situational difficulty with normal morning function often points toward psychological causes; consistent difficulty, especially with other health conditions, often points toward physical causes worth a doctor's evaluation.
