Low testosterone levels may increase the chance of premature death

Technology channels (http://) in message: United States researchers believe testosterone levels lower 40 years of male death rate than that hormone levels normal peers. But observers to the United States researchers conclusion expressed doubts as to its accuracy.

Us 858 veteran participated in this study. Detection participated in the survey's testosterone levels are respectively in 1994 and twice in 1999. Then on their health state tracking until 2002.

University of Washington and the United States Veterans Federation of health protection sector expert survey data show that testosterone levels normal participants to 53%, 28% of participants hormone fluctuations but average index close to normal. And hormone levels lower proportion of 19%.

In the subsequent observation period the level of testosterone in the normal 20 per cent of participants died, hormone fluctuations of died 24.6% hormone levels lower participants died 34.9 per cent. Having regard to the age, weight, chronic diseases, and other factors, the testosterone level of participants with low than hormone levels normal probability experiment participants killed 88 per cent higher.

The researchers did not test in the second testosterone levels by the year passed away the information of participants included, because many acute can lead to low testosterone levels. Even if this testosterone levels are low male mortality risk is higher than the same age 68 per cent.

Chair of Molly · saos is of the view that the test results prove that testosterone levels are low and the death rate increased linkages not only the effect of acute disease. In order to explain this link also in the future for new research.

United Kingdom London Royal free hospital Endocrinology House Pierre · tiemblo (Pierre Bouloux) commenting on the results of the experiment, said that United States counterparts of work there are inadequate.

Bulo says, this experimental populations — the u.s. military veterans ' Association members have their own characteristics, they themselves come from disadvantaged groups of society, in General, and will have a higher risk of early death. Therefore, this conclusion should not be extended to the general public.
