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.
According to studies, average men’s testosterone levels by age are as follows:
- 20 – 24-year-old males – 409 – 558 ng/dL
- 25 – 29-year-old males – 413 – 575 ng/dL
- 30 – 34-year-old males – 359 – 498 ng/dL
- 35 – 39-year-old males – 352 -478 ng/dL
- 40 – 44-year-old males – 350 – 473 ng/dL
According to another study, there’s been a consistent decline in testosterone levels in general over the last several decades and a 20% decline in young adult men. Currently, a sign of low testosterone in men is under 300 ng/dL.
The fact is that labeling any hormone level as normal is fruitless. Studies are meant to provide insight, but they don’t tell you what’s best for your personal situation. Normal levels of any hormone don’t mean the patient won’t have symptoms, as receptor site resistance, among other factors, can cause symptoms despite normal levels.
