They have concluded after comparing testosterone levels of five-month-old pairs of twins, both identical and non-identical.

In a test group of 115 testosterone-deficient men with a mean age of 61, hormone injections over five years yielded an average weight loss of 16 kilograms (35 pounds), said the study presented to the European Congress on Ovesity in Lyon, France.

A new study indicates a link between low levels of testosterone and frailty. Published in the July edition of the IJournal of Clinical Endocrinology and Metabolism/I, the study by researchers from the Western Australian Centre for Health and Ageing indicates a new piece of the frailty puzzle. "This is an important finding because frailty is poorly understood. We don't completely understand how people become frail, but our ...]]> http://www.medindia.net/news/Low-Testosterone-Levels-Could-Make-Elders-Frail-71282-1.htm http://www.medindia.net/news/Raise-Risk-of-Heart-Disease-in-Elderly-Men-Increased-by-High-Testosterone-Levels-70828-1.htm Older men with higher testosterone levels are more likely to have a heart attack or other cardiovascular disease in the future, alarge US multicenter study has shown. The results were presented at The Endocrine Society's 92nd Annual Meeting in San Diego. "The study finding contradicts smaller studies that have shown that testosterone levels are not associated with higher rates of cardiovascular disease," said presenting author Kristen Sueoka, MD, a resident physician at the University of California, San Francisco....]]> http://www.medindia.net/news/Raise-Risk-of-Heart-Disease-in-Elderly-Men-Increased-by-High-Testosterone-Levels-70828-1.htm http://www.medindia.net/news/Testosterone-Dose-Makes-Women-Less-Trusting-Study-69370-1.htm A recent study claims that a dose of sex hormone testosterone can make women less trusting of men. But, according to the study's researchers, the effect only seems to be true for the more trusting members of society. Tied to aggression and competitive behaviour, testosterone is produced by both sexes, although in much smaller quantities in women. In the study, published in the journal Proceedings of the National Academy of Sciences, boffins found that when testosterone is administered ...]]> http://www.medindia.net/news/Testosterone-Dose-Makes-Women-Less-Trusting-Study-69370-1.htm http://www.medindia.net/news/Brain-Oestrogen-Could-Prove-Beneficial-in-Treatment-of-Schizophrenia-69076-1.htm Experts have found that a form of oestrogen helps in reducing the symptoms of schizophrenia. The lead researcher Jayashri Kulkarni, director of the Monash Alfred psychiatry research centre, believes the hormone will be effective in men too. She led the use of standard oestrogen to treat schizophrenia after noticing that symptoms were more severe in premenstrual women. The study confirmed that brain oestrogen had a similar effect to standard oestrogen in dramatically ...]]> http://www.medindia.net/news/Brain-Oestrogen-Could-Prove-Beneficial-in-Treatment-of-Schizophrenia-69076-1.htm
