What is the normal penile/brachial systolic pressure ratio?

The normal penile/brachial systolic pressure ratio is a valuable metric used in vascular studies to assess erectile function and potential vascular impairment. In healthy individuals, the ratio reflects adequate blood flow to the penis compared to the arm. A ratio of 0.75 indicates that the systolic pressure in the penis is 75% of that in the arm, which is considered normal and indicative of good vascular health in this context.

This measurement helps clinicians determine whether there may be underlying issues affecting blood flow, such as arterial occlusion or vasculogenic erectile dysfunction. When interpreting these ratios, it's important to keep in mind that deviations from the normal range can indicate potential problems, warranting further investigation or intervention. Other ratios listed, such as 0.50, 1.00, and 0.90, do not align with established normal values in this aspect of vascular health assessment.
