The normal testosterone level is 270 to 1070 nanograms per deciliter, and anything below this range is considered a low testosterone level, according to MedicineNet. It is necessary to determine if the low level is due to normal aging or a disorder.
According to MedicineNet, most of men's testosterone is produced in their testicles. Much lower amounts are also made in women's ovaries. Testosterone is needed in men for the development of secondary sex characteristics, such as chest hair and voice deepening.
Testosterone is a sex hormone that is responsible for aiding in the development of the male sexual characteristics. Females also have minute concentrations of the hormone, but it is mostly found in males and is considered to be the principal male hormone.
Low testosterone is any measurement that falls below 300 nanograms per deciliter, according to Healthline. The condition occurs gradually as men enter old age and results in a decreased libido, hair loss, depression, weight gain, fatigue, irritability, decreased bone density and shrinking muscles.
Low testosterone or Low-T can be caused by obesity, type 2 diabetes or other chronic medical conditions like liver or kidney disease. Testosterone naturally drops as a person gets older.
Some common causes of low testosterone levels include obesity, hormonal disorders, infections and diabetes type 2. The low limit of testosterone levels in men is 300 nanograms per deciliter, while the upper normal limit is 1000 to 1200 nanograms per deciliter, notes MedicineNet.
A person can build testosterone by getting enough sleep, exercising, maintaining a healthy weight and managing stress, according to WebMD. Avoiding or reducing such drugs as opioids, glucocorticoids and anabolic steroids is necessary to enhance testosterone levels.
Excess testosterone leads to increased likelihood of excessive alcohol consumption, risky behavior, sexually transmitted diseases and a larger propensity to smoke. The higher the testosterone levels, the more likelihood of these problems, according to WebMD.
According to WebMD, testosterone is produced primarily by the testes, the main male organs of reproduction, though it is also produced in small amounts by women's ovaries. Testosterone production in the testes is conditioned by multiple factors that are mainly related to the production and maintenan
The most common test for checking testosterone levels as of 2015 is a blood test, according to WebMD. Total testosterone levels for men should fall between 270 and 1,070 nanograms per deciliter, while free testosterone levels should be from 50 to 210 picograms per milliliter.
