Can Age-Related Declines in Testosterone Levels be Prevented or Reversed?
- Published in Testosterone - Men
It is well-documented that testosterone levels decline with age in men.
After the age of 40 years, total testosterone decreases on average -4 ng/dL ( -0.124 nmol/L) per year [1] or 1.6% per year [2], and bioavailable testosterone by -2 to 3% per year. [2]
In older men (over 60 years of age), the average rate of decrement in total testosterone levels has been found to be 110 ng/dL every decade.[3]
However, the relative contributions of changes in health and lifestyle to that decline have not been adequately evaluated. A notable study was set out to investigate this...
OBJECTIVE:
The objective of this study was to establish the relative importance of aging, health, and lifestyle in contributing to the testosterone decline in aging men.[4]
