More Testosterone Research Concerning Older Men
More interesting research into Testosterone is being conducted, here are two current studies and portions of their study abstract. More information on these studies as well as other Testosterone studies can be found at http://clinicaltrials.gov/.

Older Men and Testosterone
Johan Svartberg, MD, PhD,  Principal Investigator
University Hospital of North Norway

From the study abstract: "We hypothesize that older men with subnormal testosterone levels have a varying degree of dysfunction/symptoms both physically and mentally, and that these dysfunction/symptoms can be improved with testosterone treatment."

From the study abstract: "Ageing-associated loss of muscle mass and strength is a major cause of physical frailty, disability, morbidity and dependency in the elderly. This is associated with increased falls, fractures, loss of mobility, restricted activities of daily living and increased utilisation of healthcare resources.

It is well known that serum testosterone levels fall with advancing age and this may be an important cause for muscle wasting and weakness (sarcopaenia). Testosterone replacement increases muscle mass and improves muscle strength in young hypogonadal men. In relatively healthy elderly men, some short-term studies have also shown that testosterone can improve muscle strength. The potential beneficial effects of testosterone supplementation on muscle strength and functional capacity of frail elderly men has so far not been studies and forms the basis of this research. We hypothesise that testosterone supplementation is an effective, safe and economic anabolic intervention in frail elderly men with low circulating testosterone."
