Relationship between some biological parameters and plasma testosterone in institutionalized aging men.
BACKGROUND: The decrease in circulating testosterone levels with advancing age has been shown to be related to biological changes in healthy men. OBJECTIVE: We investigated the relationship between total testosterone and several laboratory blood tests (glucose, total cholesterol, total proteins, albumin, RBC) in elderly institutionalized men (mean age: 82.7 years) with chronic illness. RESULTS: There was a dramatically low level of total testosterone in the sample and a strongly significant inverse correlation between testosterone and fasting blood glucose. Hematocrit and albumin were positively correlated to testosterone. CONCLUSION: The negative correlation between testosterone and fasting blood glucose observed in healthy men also exists in institutionalized subjects. The link between testosterone and the related other biological parameters is questioned.
