Inflammation and Erectile Dysfunction
What does inflammation have to do with erectile dysfunction? Possibly
everything according to some experts. Probably the most foundational
aspect of an erection is endothelial health and, it turns out,
endothelial health has everything to do with inflammation (or the lack thereof). In fact, one
study found that ALL of the following inflammmatory markers were associated with
erectile dysfunction: 
hs-CRP (C-Reactive Protein)

This list could continue, but the important point is that inflammation hammers
the endothelium, the lining of your afteries and blood vessels, which then hammers
your erections. This has caused some researcher to believe that inflammation is
the true root of most erectile dysfunction.
There are other indictions that this could be the case.
infections with Chlamydia pneumoniae or cytomegalovirus have been associated with erectile dysfunction
as indicated by increased inflammatory markers.
 The same has held true for gum disease as well. 
So how does chronic inflammation affect the endothelium in such a negative manner? First of all, it
lowers nitric oxide availablity. This has been observed in several
populations, one of the most notable being apnea sufferers, who
have elevated inflammation for chronic sleep interruptions.  One of the
ways inflammation controls nitric oxide is by affecting
eNOS, the stuff of Viagra.  Yes, inflammation is the ultimate anti-Viagra in
Affecting NOS negatively is potentially dangerous in the long term as well, because nitric oxide
decreases the damage done to arterial walls. So as chronic inflammation
turns off your nitric oxide, additional damage occurs to the endothelium, which
in turn leads to decreased nitric oxide and so on.
The bottom line: to avoid erectile dysfunction, you have to get this Enemy
#1 in control. Remember, this will also decrease your cancer and
cardiovascular risks as well. Read my links on How to Decrease
Inflammation and Juicing and Inflammation for starters.
