Testosterone deficiency

An abnormally low testosterone level in men, known as hypogonadism, is treated with testosterone, but it is not clear if testosterone is a safe or effective treatment for so-called low testosterone, such as the lower levels of testosterone typically found in older men. In men with lower testosterone, the level can often be raised by increasing exercise, improving diet, and reducing weight to the recommended range. For many years, synthetic steroids similar to testosterone have been used by athletes with the goal of improving performance, but medical research has shown that these drugs may have a wide range of harmful side effects and their use is now typically banned. As a man ages, the amount of testosterone in his body naturally gradually declines. This decline starts after age 30 and continues throughout life. Some causes of low testosterone levels are due to Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss. Furthermore testosterone levels gradually decrease as men age. Hence synthetic testosterone is sometimes prescribed to older men to counter act this deficiency. Reference

Symptoms of the condition in males consist of loss of libido, impotence, infertility, shrinkage of the testicles, penis, and prostate, diminished masculinization, low muscle mass, anxiety, depression, fatigue, hot flashes, insomnia, headaches, and osteoporosis. In addition, symptoms of hyperestrogenism, such as gynecomastia and feminization, may be concurrently present in males. Low testosterone can be identified through a simple blood test performed by a laboratory, ordered by a physician. This test is typically ordered in the morning hours, when levels are highest, as levels can drop by as much as 13% during the day. Normal total testosterone levels range from 240–950 ng/dL. Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss. Furthermore testosterone levels gradually decrease as men age. Hence synthetic testosterone is sometimes prescribed to older men to counter act this deficiency. Reference

Treatment is often prescribed for total testosterone levels below 230 ng/dL. If the serum total testosterone level is between 230 and 350 ng/dL, repeating the measurement of total testosterone with sex hormone-binding globulin to calculate free testosterone or free testosterone by equilibrium dialysis may be helpful. Testosterone production declines naturally with age. Low testosterone, or testosterone deficiency, may result from disease or damage to the hypothalamus, pituitary gland or testicles that inhibits hormone secretion and testosterone production, and is also known as hypogonadism. Depending on age, insufficient testosterone production can lead to abnormalities in muscle and bone development, underdeveloped genitalia and diminished virility. The standard range given is based off widely varying ages and, given that testosterone levels naturally decrease as humans age, age-group specific averages should be taken into consideration when discussing treatment between doctor and patient. In men, testosterone falls approximately 1 to 3 percent each year. Reference
