Look for a trend, not perfection
Erections naturally vary. Ask whether reliability has clearly changed from your usual baseline and whether the problem occurs across different situations.
Common short-term disruptors
Fatigue, distraction, performance pressure, relationship conflict, alcohol and acute illness can temporarily affect the response. A short-term trigger can still coexist with a medical contributor.
Reasons to arrange a review
Book a clinician visit when the pattern continues, creates distress, follows a medication change or appears with reduced exercise tolerance, urinary changes, pain, curvature or loss of sensation.
