Erectile dysfunction associated with gum disease

Erectile dysfunction is defined as the inability to have an erection due to organic, psychological causes or a combination of these. Periodontitis is a chronic inflammation of the gums with the destruction of the alveolar process and connective tissue that surround and support the tooth and lead to its loss.

In this disease, periodontal bacteria or inflammatory cytokines that have arisen in the center of the gum damage the vascular endothelium. When this endothelial dysfunction occurs in the vessels of the penis, the blood flow in this organ is broken, and sexual impotence occurs.


The study involved 158 volunteers: 80 men with erectile dysfunction were treated in the urology department of the San Cecilio Hospital in Granada, and another 78 people were in the control group. Socio-demographic data were collected, periodontal examination and analysis were conducted to measure testosterone, lipid profile, C-reactive protein, glycemia and glycosylated hemoglobin. The results showed that 74% of patients with erectile dysfunction had periodontitis. Patients with greater dysfunction had greater periodontal trauma.

According to the results, male periodontitis is 2.28 times more likely to suffer from sexual impotence than a healthy periodontium, and the associated biochemical variables include triglyceride levels, C-reactive protein and glycosylated hemoglobin.

Gingivitis is an oral disease caused by the bacterium Porphyromonas gingivalis, which causes inflammation and bleeding of the gums and can lead to tooth loss. And now a team from the University of Louisville has found a link between this oral disorder and Alzheimer's disease. In tests on mice, researchers found that the oral infection caused by this bacterium can also colonize the brain and stimulate the appearance of plaques of beta-amyloid protein, one of the main causes of Alzheimer's disease.
