title: Doppler blood flow analysis of erectile function: who, when, and how.
abstract: The underlying processes in vasculogenic erectile dysfunction (ED) are arterial insufficiency, venoocclusive disease, or combinations of both. Doppler blood flow analysis is a diagnostic modality useful in elucidating the cause of ED and the magnitude of its severity. This article describes the procedural techniques, typical findings, and relevant pathophysiology for in-office Doppler studies. Specific conditions include arterial insufficiency, venous occlusive disease, Peyronie's disease, and priapism.
