The March 2010 edition of the Journal of Clinical Endocrinology and Metabolism states that decreased Free Testosterone (unbound to protein) in men caused by aging, disease, or trauma, leads to atherosclerosis of the aorta, which creates a high risk of Aortic Aneurism.
It has long been accepted that low testosterone in aging men is associated with ill health: diabetes, frailty, osteoporosis, sexual malfunction, stroke, heart disease, and other illnesses associated with aging. This study was to determine if the Free Testosterone level was related to the lack of the Testosterone, as is heart disease.
Researchers found a correlation between low Testosterone and Aortic Aneurism. In realizing this conclusion they also acknowledge that low testosterone is associated with high inflammation of the arteries, which is one of the sources of cardiac disease.
This supports what I have been saying about preventing disease by replacing your missing Testosterone.
