Levels tend to be lowest around 8 in the afternoon and then rise during the night. Peaks and valleys are larger for men in their 40s and younger compared to men in their 70s. For a 40-year-old, a morning testosterone reading may be 200 points higher than at night, compared to a 50-point difference for a 70-year-old person. What complicates this issue is the fact that testosterone levels don't stay the same throughout life, during the year, or even during the day, at least in men.
Testosterone levels change throughout the day in men, peak around 4 to 8 in the morning and fall to their lowest level approximately 12 hours later. They can also vary throughout the year, although these seasonal highs and lows will differ around the world. These daily and seasonal variations can cause levels to change by up to 19%. Making these lifestyle changes, along with hormone replacement therapy through testosterone supplements, can increase a man's testosterone levels.
It is best known for its role in the development of male sexual and physical characteristics, but there are also many surprising and lesser-known functions of testosterone that make it an important hormone for health and disease. Testosterone levels in men's blood are thought to decrease with age, although in reality this may be more related to diseases that occur with age. While a pill may be convenient, it comes with greater risks than other forms of testosterone supplements. Low testosterone levels are a condition in which the testicles do not produce the male sex hormone testosterone.
However, research seeks to define levels that are healthy and levels that may be related to the disease in order to identify and treat patients. Therefore, what might be considered a low level for a person may be OK if they have a more sensitive receptor capable of carrying out the actions of testosterone at lower concentrations. In reality, many of these symptoms are the same in women who also have low testosterone levels, and research now suggests that low testosterone levels may be a risk factor for developing heart disease, diabetes and obesity in both men and women.

This level increases again during puberty, causing children to develop armpit hair, accelerate growth, and develop sexually. Some laboratories report testosterone levels of up to 800 or 1000, but the average man probably doesn't measure those levels, and having a significantly higher testosterone level has no benefit. Using the average testosterone levels of many people from different populations to establish normal levels is useful to help identify people outside this range with a related condition. Similarly, certain diseases in women that cause high levels of testosterone also carry similar risks of heart disease.
The condition of low testosterone levels, also called hypogonadism, refers to an inadequate amount of testosterone to stimulate male hormone receptors in certain cells of the body, such as in male reproductive organs, muscles and bones. Establishing a “normal” level is complex, and measuring testosterone alone may not be enough to estimate the correct blood level for a particular person to have. .
