The promise of testosterone therapy may seem enticing, but there are a lot of misconceptions about what the treatment can and can't do for you. As you get older, testosterone therapy may sound like the ultimate anti aging formula. Testosterone is produced by the gonads although small quantities are also produced by the adrenal glands in both sexes. It is an androgen, meaning that it stimulates the development of male characteristics.
Yet the health benefits of testosterone therapy for age related decline in testosterone aren't as clear as they may seem. Find out what's known and not known about testosterone therapy for normal aging. In women, testosterone is produced by the ovaries and adrenal glands. The majority of testosterone produced in the ovary is converted to the principle female sex hormone, oestradiol.
Testosterone levels generally peak during adolescence and early adulthood. As you get older, your testosterone level gradually declines typically about 1 percent a year after age 30 or 40. It is important to determine in older men if a low testosterone level is simply due to the decline of normal aging or if it is due to a disease. The regulation of testosterone production is tightly controlled to maintain normal levels in blood, although levels are usually highest in the morning and fall after that. The hypothalamus and the pituitary gland are important in controlling the amount of testosterone produced by the testes.
Hypogonadism is a disease in which the body is unable to produce normal amounts of testosterone due to a problem with the testicles or with the pituitary gland that controls the testicles. Testosterone replacement therapy can improve the signs and symptoms of low testosterone in these men. Doctors may prescribe testosterone as injections, pellets, patches or gels.
Not necessarily. Men can experience many signs and symptoms as they age. Some may occur as a result of lower testosterone levels and can include Changes in sexual function. This may include reduced sexual desire, fewer spontaneous erections such as during sleep and infertility. Changes in sleep patterns. Sometimes low testosterone causes insomnia or other sleep disturbances. Physical changes. Various physical changes are possible, including increased body fat, reduced muscle bulk and strength, and decreased bone density. Swollen or tender breasts and body hair loss are possible. You may have less energy than you used to.
Some of these signs and symptoms can be caused by various underlying factors, including medication side effects, obstructive sleep apnea, thyroid problems, diabetes and depression. It's also possible that these conditions may be the cause of low testosterone levels, and treatment of these problems may cause testosterone levels to rise. A blood test is the only way to diagnose a low testosterone level. Emotional changes. Low testosterone may contribute to a decrease in motivation or self-confidence. You may feel sad or depressed, or have trouble concentrating or remembering things.
Testosterone therapy can help reverse the effects of hypogonadism, but it's unclear whether testosterone therapy would have any benefit for older men who are otherwise healthy. The effect excess testosterone has on the body depends on both age and sex. It is unlikely that adult men will develop a disorder in which they produce too much testosterone and it is often difficult to spot that an adult male has too much testosterone. Although some men believe that taking testosterone medications may help them feel younger and more vigorous as they age, few rigorous studies have examined testosterone therapy in men who have healthy testosterone levels. And some small studies have revealed mixed results. For example, in one study healthy men who took testosterone medications increased muscle mass but didn't gain strength.
Low testosterone levels can cause mood disturbances, increased body fat, loss of muscle tone, inadequate erections and poor sexual performance, osteoporosis, difficulty with concentration, memory loss and sleep difficulties. Limit sperm production or cause testicle shrinkage Increase the risk of a blood clot forming in a deep vein, which could break loose, travel through your bloodstream and lodge in your lungs, blocking blood flow In addition, testosterone therapy may impact your risk of heart disease. Research has had conflicting results, so the exact risk isn't clear yet.
If you wonder whether testosterone therapy might be right for you, talk with your doctor about the risks and benefits. Your doctor will likely measure your testosterone levels at least twice before discussing whether testosterone therapy is an option for you. A medical condition that leads to an unusual decline in testosterone may be a reason to take supplemental testosterone. However, treating normal aging with testosterone therapy is not currently advisable.
