Testosterone patch helps aging men

Melbourne, Dec 30 (UNI) Treatment with testosterone can help curb the gain in abdominal fat as well as the loss of skeletal muscle seen in non-obese aging men, according to a new study.

''Though use of testosterone therapy as a means of defying the aging process is gaining popularity, data from scientific trials have been very limited in this area,'' study chief Dr Carolyn Allan, from Prince Henry's Institute in Victoria, Australia, said in a statement.

''Our findings indicate that maintaining testosterone at 'young adult' levels may indeed prevent the adverse changes in body composition associated with the aging process,'' The Bulletin quoted Dr Allan as saying.

In the study, 60 healthy men who were at least 55 years of age with low-normal testosterone levels wore a testosterone patch or placebo patch for 12 months, Dr Allan said. The men underwent body composition assessment and metabolic testing at the beginning and end of the study, he added.

Men taking the hormone experienced a 30 per cent increase in serum testosterone levels. The control group, by contrast, saw their testosterone levels fall by 10 per cent, the research found.

Men in the testosterone arm also experienced increase in fat free mass and skeletal muscle and loss of thigh skeletal muscle was decreased, it informed.

A drop in abdominal fat accumulation with no change in total body or abdominal subcutaneous fat mass was also noted in the testosterone group. Further analysis showed that the change in abdominal fat correlated with the change in testosterone levels, the report indicates.

These findings, the researchers conclude, suggest a role for testosterone in modifying the age-related increase in abdominal fat and possibly associated harmful metabolic changes.
