Penile Doppler ultrasound is a vital tool for evaluating vascular causes of erectile dysfunction. In a normal study, adequate arterial inflow is demonstrated by a peak systolic velocity (PSV) greater than 30–35 cm/s, and proper venous occlusion is confirmed by a low end diastolic velocity (EDV) approaching zero. This pattern supports the achievement and maintenance of a firm erection. In contrast, the abnormal case shows a PSV less than 25 cm/s, indicating arterial insufficiency, and a persistently elevated EDV of 5–9 cm/s with continuous diastolic flow, suggesting a venous leak. Together, these findings point to mixed vascular erectile dysfunction. Early diagnosis through penile Doppler is crucial for guiding appropriate management strategies and improving patient outcomes, emphasizing the need for a comprehensive vascular assessment in men with erectile dysfunction.
