Testosterone is a hormone present in men but also crucial in women. What happens to the athlete if the Testosterone is low?
Before starting to think “I have low Testosterone, what can I do ” it is good to talk to your doctor and add the test to the next blood tests.
The blood test measures the concentration of testosterone in the blood (T), as total testosterone or in combination with free and / or physiologically bioactive testosterone.
When the T levels are tested, the reference range can also be particularly different between laboratories, it is therefore advisable to always carry out the tests in the first laboratory or to ask to verify the compatibility before analysis. Check out the Best testosterone booster.
However, Testosterone levels are in a “fork” which can also be particularly wide:
Bottom margin between 160-300 nanograms per deciliter, or ng / dL
Upper margin between 726-1,130 ng / dL.
Thus, depending on the laboratory, a level of 250 ng / dL could be regarded as a below-the-norm level of Testosterone.
In women, however, the area considered “normal” has values between 8 and 60 ng / dl
Testosterone varies throughout the day, so it is always necessary to test in the morning.

Testosterone production is stimulated and controlled by luteinizing hormone (LH), produced at the pituitary level. The body regulates the amount of testosterone in the blood via a negative feedback mechanism:
Low testosterone levels increase the pituitary secretion of LH, which stimulates testosterone production.
High testosterone levels reduce pituitary LH secretion, resulting in inhibition of testosterone production.
