A report published in the July 2009 edition of the Journal of Clinical Endocrinology and Metabolism states that when looking at health markers (levels of hormones, risk factors, etc.), low Testosterone for men and a low estradiol for women are markers for higher risk of death from other diseases.
Dr. John Morley, local researcher, physician and head of geriatrics at St. Louis University, published an article stating that Testosterone supplementation improves spacial perception and eye hand coordination. He also reports that Testosterone helps older men improve bone density, and muscle mass and strength, making it possible for them to move around more easily.
Dr. Ian Chapman from Australia found that treating both men and women in nursing homes with testosterone decreased the number of times they were hospitalized. He suggests that aging patients will benefit from Testosterone replacement.
