Testosterone is a male hormone that is present in both males and females. It is one of the essential hormones for the production of sexual hormones throughout the human body. Testosterone also plays a critical role in male puberty and reproduction, in male sexual differentiation, and in the maintenance of body fat. In males, testosterone also plays a critical role in the normal growth of male secondary sexual characteristics including increased bone and muscle mass, and increased body hair. Testosterone replacement therapy has been used for many years to treat symptoms of these conditions in men.


Testosterone replacement therapy can be used to treat symptoms of hypogonadism as well. This is a medical condition where the pituitary gland produces less than the normal amount of testosterone because of malfunctioning of the hypothalamus or pituitary gland. This deficiency can cause symptoms including decreased libido, increased body fat, muscular weakness, erectile dysfunction, and depression. Because testosterone levels are often the underlying cause of these symptoms, taking testosterone supplements can be effective in correcting the issues behind them. It is important to note, however, that testosterone replacement therapy should only be used with the recommendation of a doctor because the hormone may increase the risk of certain serious side effects.

Testosterone deficiency can also lead to decreased muscle mass and strength, and low muscle mass and strength are major symptoms of low testosterone levels. Testosterone is an anabolic hormone and is required in the generation of muscle tissue. As muscle cells begin to proliferate in men suffering from testosterone deficiency, testosterone levels begin to drop. The reduction in muscle mass and strength results in diminished physical performance and increased fat deposits. This can ultimately lead to the loss of muscle, anorexia, depression, low energy levels and other psychological disorders.

Testosterone replacement therapy has been proven successful in correcting many symptoms of low testosterone. In fact, it has become a billion-dollar industry. Many pharmaceutical companies have created drugs called Testarol and Anabolic steroids that are designed to boost levels of the hormone in men suffering from low testosterone symptoms. However, some of these drugs have dangerous side effects that have led to reports of sudden death from heart attacks, cardiac arrest and even organ failure.

Testosterone replacement is not the only option for correcting low testosterone levels. In some cases, low testosterone levels can be corrected by nutritional supplements. Because the hormone regulates many processes in the body, particularly the energy-generating processes of the body, low levels of this hormone can interfere with energy production and protein synthesis in the body. As a result, low levels of testosterone can lead to lack of energy, fat gain and a decrease in muscle mass and strength.

To correct these symptoms, doctors commonly prescribe synthetic hormones like Testarol and Anabolic steroids that increase testosterone levels through the action of an enzyme. However, risks associated with these medications have kept many people from taking them. Testosterone replacement through injections is very expensive and carries serious risks. Moreover, the effects of these drugs depend on the dose taken. In most cases, low levels of Testosterone prevent testicular growth but when levels are high enough, the effects of the drugs can be opposite. In some extreme situations, the treatment can cause testicular failure or even death.

There are alternatives to testosterone replacement. In most cases, the treatment involves the replacement of the naturally occurring sex hormone with synthetic versions. Synthetic Testosterone mimics the effects of testosterone by acting on the pituitary gland, which produces the hormone.

A blood test that measures testosterone levels in saliva can help a doctor to diagnose low levels of the male sex hormone. In the case of a diagnosis of low testosterone levels, the doctor will likely recommend that the patient undergo testosterone therapy. The type of therapy will vary according to the age, health condition, and the type of deficiency. In some cases, intramuscular injections are required. To get the best results, a doctor should follow all of the guidelines laid down by the American Association for Clinical Endocrinology.
