What does Right Artery - PSV = 0.50 m/s,Left Artery - EDV = 0.02 m/s indicate?

I had a penile doppler ultrasound investigation last month and my results were:

Left artery - PSV = 0.47m/s

Right Artery - PSV = 0.50m/s

Left Artery - EDV = 0.02m/s

Right Artery - EDV = 0.01m/s

Left - RI = 0.98

Right - RI = 0.97

I only got a 60% erection during the investigation, I had no libido. I've had full morning erections before. Earlier this year I got a full morning erection that stayed up for 20 minutes and still get partial morning erections at times.

From what I've been reading the PSV is normal but I'm wondering if I got a full erection during the investigation; would the readings have been higher? And what about the EDV values? Are they ok? I had an investigation a few years ago and there was nothing physically wrong with me.

Hi,
Thanks for writing in.

PSV is peak systolic velocity and for you it is in the range of 47 to 50 cm/ second which is normal.

EDV is end diastolic velocity and it is 1 to 2 cm/ second is a dynamic variable. EDV in a normal penile Doppler decreases with increase in erection and at full erection a negative value is obtained due to flow reversal.

This has not been commented up on in the report so I assume the erection might not have been total.

There are many reasons for less than total erection including addiction, smoking and medical conditions.
