Low testosterone – symptom, causes and associated risk factors

Low testosterone

When people are thinking of declining levels of testosterone, then they might think of middle – aged or older men. But it is known fact that men who are under 30 can experience low testosterone or “low T”. There are some studies in which are said that testosterone levels tend to peak in men during adolescence and early adulthood. These levels typically decline by about 1% each year and it is starting around age 30. But there are some cases when men can experience declining testosterone levels at a younger age. Low testosterone is a condition in which the body does not produce enough of the hormone testosterone. It is known that both males and females are producing testosterone but it is called “male hormone” because men produce a lot more of it. This hormone is critical for many male characteristics in which are included hair growth, voice deepening, muscle mass development, sperm development and maturation of male sex organs.

The low testosterone can cause many different symptoms such as balding, fat gain, muscle mass loss, infertility and erectile dysfunction. If you think that you have low testosterone levels, then you should talk with your doctor as soon as possible. After age of 30, most men begin to experience a gradual decline in their testosterone levels. When there is a decrease of sex drive, there are some cases when it accompanies the drop in testosterone which is leading many men to think that their loss if interest in sex is caused by getting older. It is known fact that the bottom of a man’s normal total testosterone range is about 300 ng/dL (nanograms per deciliter) and the upper limit of testosterone levels is about 800 ng/dL (nanograms per deciliter) and this depends on the lab. There are many conditions which can lead to lower than normal score on a blood test such as obesity, type 2 diabetes, chronic liver or kidney disease, HIV/AIDS, infection, hormonal disorders, testicular cancer or treatment for testicular cancer and injury to the testicles. There are some cases when low testosterone is caused by an underlying medical condition which requires treatment. In other cases it is caused by unhealthy lifestyle habits which you can change.
