If you have had your testosterone levels tested, you may find yourself a bit confused when you get back the results. You’ll notice that there isn’t just one type of testosterone. There is “free testosterone,” “bound testosterone,” and “bioavailable testosterone.”
Maybe your report says that your bioavailable testosterone levels are low. What does that mean?
There are two types of testosterone in your blood:
- Free testosterone: This accounts for less than 4% of your total testosterone.
- Bound testosterone: This accounts for around 96% of total testosterone.
Bound testosterone may be bound to either the main protein in your blood (known as albumin) or a protein known as a sex hormone binding globulin (SHBG). Usually around one third of bound testosterone is bound to albumin; around two-thirds is typically bound to SHBG. There can however be quite a bit of variation in the percentages.
The bond which connects testosterone to albumin is not as strong as the bond which connects it to SHBG.
That means that if you may have a higher percentage of loosely-bound testosterone than strongly-bound testosterone.
BiovAvailable Testosterone Definition
“Bioavailable testosterone” refers to the sum total of your free testosterone plus your albumin-bound testosterone.
Testosterone that is bioavailable is more readily able to enter your cells and be used by your body. This is why it is important to get this reading and not just your serum total testosterone.
You could have the exact same total testosterone reading as another man, but have comparatively low bioavailable testosterone. If the only measure that was taken was the total levels, you would not understand why you had symptoms of testosterone deficiency while the other man did not. Getting both measurements gives you a much more comprehensive picture of what is going on in your body.
Sometimes there is a medical cause for low testosterone which may need separate treatment. This is something to talk to your doctor about. Oftentimes, testosterone levels decline simply because of age.
What Can You Do About Low BioAvailable Testosterone?
If you find that you do not have normal bioavailable testosterone levels, it may feel like a punch in the gut.
But it is also knowledge, and knowledge is power. If you have been experiencing the symptoms of low testosterone, you will finally have the answer you have been searching for.
So what are your next steps?
At this point your doctor may start trying to prescribe you hormone replacement therapy (HRT).
HRT is a drastic solution though and may cause other problems in your body.
One way you can increase libido naturally is to take a testosterone booster instead. This is an herbal supplement that stimulates the production of bioavailable testosterone in your body. Natural libido boosters for men do not contain hormones. They simply help your body to do what it already does, but with greater efficiency.
This also means that they go into effect more gradually, but produce more balanced long-term results, usually with fewer side effects.
Once your body is producing more bioavailable testosterone, you symptoms should diminish, and may even go away altogether. Men who use testosterone boosters report that they perform better in bed and in the gym, have more energy, and generally feel more confident about themselves.
