Male Androgen Levels in an Unhealthy Population
Depending on the lab your doctor uses, male testosterone levels typically range between 250ng/dl and 850 ng/dl.
As you may well imagine, these ranges are not set to optimal levels. They are a cross section of men aged 20 to 100; many sick and diseased, from a lifetime of unhealthy habits.
So when your blood work arrives and your doctor refuses treatment due to your "normal" testosterone levels, when it's actually somewhere closer to the bottom of the range, then a gentle reminder of optimal health may be in order.
If you kindly point out you have the T levels of a sick 90 year old, maybe he/she will come around.
Emphasize Low Testosterone Symptoms
If your doctor is stubborn, or doesn't like their patients being active participants in their own healthcare... you may be better off emphasizing your symptoms that are more specific to low testosterone.
Noting a loss of sex drive, development of impotence, or reduced muscle mass and strength should give any knowledgeable doctor a red flag that T levels aren't on par.
Depression, fatigue, and loss of motivation are also commonly caused by low testosterone. Unfortunately many doctors would rather prescribe an antidepressant than bring back to normal a natural substance your body already makes.
