Testosterone is the primary male sex hormone and an anabolic steroid. In men, testosterone plays a key role in the development of male reproductive tissues such as the testis and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. In addition, testosterone is involved in health and well-being, and the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss.
We can see that normal testosterone level plays an important role in men and abnormal testosterone level will cause a series of problems. Once you found your testosterone level is abnormal, you should attach importance to it because earlier detection, better treatment.
A man’s testosterone levels will typically peak somewhere between age 20 and 30. After this time, they will gradually decrease for the rest of his life. Testosterone levels are estimated to decrease by 1 percent annually after age 30 to 40. Therefore, lower testosterone levels are more common among older men. This explains some of the age-related changes in men, such as loss of muscle mass.
Testosterone therapy is usually given for one of two reasons. Some men suffer from a condition known as hypogonadism. If you have hypogonadism, your body doesn’t make enough testosterone. Testosterone is important. It plays a key role in the development and maintenance of male physical traits. Taking testosterone steroids is the most direct way to add testosterone content.
Testosterone levels start to decline in men after age 30, but the decline is gradual. That decrease in testosterone is the second reason a man may be given testosterone therapy. Some men want to make up for the lost muscle mass and sex drive that results from this natural decrease in testosterone.
