Low testosterone levels associated with increased risk of death in men

If you are a male over the age of 40, go check up regularly, and have your doctor look at your testosterone levels; EurekAlert writes:

“Men who have a low testosterone level after age 40 may have a higher risk of death over a four-year period than those with normal levels of the hormone, according to a report in the August 14/28 issue of Archives of Internal Medicine.

Men with low testosterone levels had an 88 percent increase in risk of death compared with those who had normal levels. When the researchers considered other variables that may influence risk of death, such as age, other illnesses and body mass index, the association between low testosterone levels and death persisted.”

There are more diseases/conditions that science associate with low testosterone levels, such as an increased Alzheimer risk:

“Older men with lower blood levels of testosterone, the primary male sex hormone, could have a higher risk of developing Alzheimer’s disease than older men with comparatively higher testosterone levels. Researchers funded by the National Institute on Aging (NIA) report preliminary data supporting this conclusion in the January 2004 issue of Neurology.”

The May issue of Life Extension Magazine has an article explaining what they think is the 10 most important blood tests. In the article introduction we learn:

“Sadly, most annual medical check-ups involve the physician ordering only routine blood tests, if blood tests are ordered at all. Far too often, this blood work does not even test for important markers of disease risk. The consequences of failing to analyze blood for proven markers of disease risk are needless disability and death.

Blood tests have benefits that go far beyond disease prevention. In this article, we discuss the 10 most important blood tests that people over the age of 40 should have each year. Armed with the results of these tests, aging adults can work together with their physicians to avert serious health problems and achieve optimal health.”

And under subheading 9. Testosterone we can read:

“In men, testosterone levels normally decline with age, dropping to approximately 65% of young adult levels by age 75. This drop in testosterone is partially responsible for the significant physiological changes seen in aging men.

Low levels of testosterone are associated with numerous adverse health conditions, including diminished libido, metabolic syndrome, erectile dysfunction, loss of muscle tone, increased abdominal fat, low bone density, depression, Alzheimer’s disease, type II diabetes, and atherosclerosis. New research shows that low testosterone levels are a risk factor for ischemic heart disease in men.”

  1. This is an interesting article. Usually you just focus on increasing testosterone with the idea of increasing muscle, not increasing lif expectancy.

  2. I know another doctor that has been focusing recently on this very issue. Have to talk to my over-50 BF about this. I’m into sports nutrition myself, but this adds a new wrinkle.

  3. Another equally important hormone to test in blood is “pregnenolone.” This is known as “the mother of all hormones” because you need it for your body to produce testosterone and every other hormone needed by your body.

    My husband (age 52) was found to have extremely low levels of pregnenolone so we started supplementing at 50 mg. (available at Whole Foods) and his energy level shot up in just 24 hours!

    Women also should be tested for this essential hormone!
