Erectile dysfunction is associated with gum inflammation

Erectile dysfunction is defined as the inability to get an erection due to organic, psychological reasons, or a combination of both. Periodontitis is a chronic inflammation of the gum with the destruction of the alveolar bone and connective tissue, which surrounds and supports the tooth and leads to its loss.

In this disease, periodontal bacteria or inflammatory cytokines, which are caused by gingival foci, injure vascular endothelium. When this endothelial dysfunction appears in the penis vessels, blood flow in this organ is impaired and sexual impotence occurs.


158 volunteers participated in the study: 80 men with erectile dysfunction treatment at the Urology Department of the Granada San Cecilio Hospital and another 78 who were members of the control group. Sociodemographic data were collected, periodontal examinations and analyzes were performed to determine testosterone levels, lipid profile, C-reactive protein, glycemic and glycosylated hemoglobin. The results showed that 74% of patients with erectile dysfunction showed periodontitis. Patients with greater dysfunction had greater periodontal damage.

According to the results, men were 2.28 times more likely to suffer from sexual impotence than periodontal healthy, and the associated biochemical variables were triglycerides, C-reactive protein and glycosylated hemoglobin.

Gingivitis is an oral disease caused by the bacterium Porphyromonas gingivalis, which causes gum inflammation and bleeding, and which can cause tooth loss. And now, the Louisville University team found a link between this mouth disorder and Alzheimer's disease. In mice, researchers have observed that oral infection by this bacterium can also colonize the brain and stimulate beta-amyloid protein plaques, one of the major causes of Alzheimer's disease.
