"It is normal and typical for testosterone levels to decrease in men as they grow older. After the age of forty, a decrease of approximately .3% annually is common. Testosterone levels between 250 and 800 nanograms per deciliter of blood are considered to be within the normal range. Men often experience fluctuations in their own level of testosterone seasonally or even daily. Exercise levels have also been shown to cause measurable changes. Approximately 20% of men above age sixty have levels that consistently fall below this normal range.
Certain studies suggest that men aged fifty or older with lower than normal testosterone are 33% more likely to die than their counterparts with normal levels. The studies took into consideration age, lifestyle, and their overall physical fitness level."
