What is the normal PSV range for cavernous arteries of the penis?

The normal peak systolic velocity (PSV) range for the cavernous arteries of the penis is indeed approximately 30 cm/sec or higher. This measurement is crucial in evaluating penile blood flow, particularly in the context of erectile function assessments. A PSV of 30 cm/sec or above indicates adequate arterial flow, which is necessary for the physiological process of erection.

Within the normal range, this velocity suggests that the cavernous arteries can sufficiently fill the corpora cavernosa during sexual arousal, leading to the engorgement needed for erection. Lower PSV values might indicate potential erectile dysfunction or insufficient arterial perfusion, which could be due to various vascular diseases, including atherosclerosis or other flow-limiting conditions.

Understanding this normal PSV range is key for healthcare providers conducting penile Doppler ultrasound studies, as it assists in diagnosing vascular causes of erectile dysfunction.
