Sources of ED Introduction: Part 2
So, an erection is ultimately a blood vessel (called ‘vascular’) event and it depends upon the balance between arterial blood inflow and venous blood outflow. Simply put, when the inflow is low and outflow balances it, your Dick is flaccid, but when inflow increases and outflow is restricted, he erects.
This insight into the Nitric Oxide cause of the blood inflow into your Dick was identified by a trio of brilliant researchers at UCLA: Lou J. Ignarro, Robert F. Furchgott and Ferid Murad. These guys identified the relaxation in penile tissue caused by the release of Nitric Oxide through cCMP in the lining of penile blood vessels. We all owe Lou et al. a huge thank you for putting ED Therapy on the right track and away from quack potions and contraptions. They did get the 1998 Nobel prize for Medicine out of it, but that is trivial compared to the number of erections – and consequent orgasmic sex encounters – that have occurred as a result of their work. Their work and subsequent reported research as well as the sexual stimulation that expresses your sexual needs underlies my Step by Step Therapy.
I would like to point out that it is obvious that anything that affects the underlined above and the normal blood flow or the release of the Nitric Oxide will contribute to ED and is a source of ED. This “anything” can be psychological, physical, or a combination of both. Roughly 90% of all men who suffer from an ED condition get it from a predominantly a physical source. The rest acquire the condition from predominantly psychological causes.
