Here are the factors that influence levels of testosterone measurements:
Testosterone Levels range
The normal range of human testosterone range is 260 to 1,000 nanograms (ng) per deciliter (dL) of blood.
age
Testosterone levels in men varies with age. A man has the highest testosterone at about 25 years old with an average level of 692 ng / dl.
Between the ages of 55 to 59 years, the average testosterone level will decrease to about 552 ng / dl.
Daily fluctuations
Testosterone levels rise and fall throughout the day. Peak levels of testosterone generally occurs between the hours of 4:00 to 8:00, then fell to the lowest level in at 4:00 p.m. to 8:00 p.m..
sport
Exercise will increase testosterone men. That is why, it is better not to exercise prior to the measurement of testosterone levels to determine the truth.
measuring Testosterone
Testosterone can be measured in several different ways. There are two types of testosterone and free testosterone that is bound.
Free testosterone is not bound to proteins or other hormones. In contrast, unbound testosterone binds to proteins or other hormones.
Testosterone measurement will measure two types of free and bound testosterone.
