Led by researchers in Europe, a recent study published in the Journal of Sexual Medicine found that men with severe periodontal disease were more than three times more likely to suffer from erectile dysfunction than the men with healthy gums were. 

Our results have suggested that CP had a high association with ED in young adults at 30–40 years. We think that it will be of benefit to consider periodontal disease as a causative clinical condition of ED in such patients

More research is needed to study the potentially causal relationship between gum disease and erectile dysfunction; however, given what is already known about the effects of oral health on vascular inflammation, it is not a far reach to see oral inflammation listed as an important component of this condition.
