For those of you in the UK who you wish to persue VED therapy, you may be interested in attending the VED clinic at UCLH. They follow the approach used in the UK VED study, demonstrating the model and advising how to use it and how not to. You are able to contact the VED clinic for advice anytime if you are having problems using it. If you have fit specific criteria (erectile dysfuntion etc), you may be able to get the VED for free on the NHS. If not, you'll likely have to pay for it. Your GP will decide. Either way, it's useful to have a support system in place.
You'll need to contact Dr Ralph at UCLH, London using the NHS Freedom to Choose scheme to take part. A referral from your GP will get the ball rolling.
As stated, the routine used here mirrors that used in the VED study:
"The VED device is to be used 2 x a day for 10 minutes each time. You are directed to pump up the penis and hold the erection for 20 seconds then releasing the pressure and starting over again."
It differs somewhat from the Chris Spivey Vacuum Therapy protocol, where three cylinders are used instead one one, and vacuum hold time is less. Word is that you've had good results at the UK VED clinic.
