The Decline in Testosterone Levels as We Age

Since testosterone levels begin to decline in the mid-thirties, by the time you reach 70 years of age, there could be a decline of as much as 30%. Of course, various factors can affect testosterone levels, but when they drop to below-normal levels, they can affect all areas of physical and mental health. According to a study, testosterone levels are more closely related to behavioral and health-related issues than aging.

When levels dip below 200 ng/dL, even if you feel okay, other health-related symptoms could appear that can jeopardize health, such as reduced bone density and cognitive decline.
