Testosterone Deficiency Syndrome (Hypogonadism)
Testosterone Deficiency Syndrome, or Hypogonadism, is a condition in which a man's body does not make enough testosterone, the primary male hormone. This condition usually affects older men, but younger individuals can also be affected for a variety of reasons.
While the term "andropause" is sometimes used for this condition, it is inaccurate. Unlike menopause, testosterone deficiency syndrome is not an inevitable result of aging.
Testosterone plays a key part in a man's sex drive, muscle mass, along with mental and physical energy.
Symptoms
There are a number of symptoms that are associated with a deficiency in testosterone in men:
Causes
Sometimes, a specific cause for testosterone deficiency may be identified. An example would be excess secretion of one or more pituitary hormones that then interfere with testosterone production or availability.
In most people, however, no cause for testosterone deficiency can be identified. In these cases, testosterone replacement therapy is generally an effective treatment.
Effects
Beyond the symptoms that many men experience, testosterone deficiency syndrome can also contribute to the beginning or worsening of various diseases:
Diagnosis
Testosterone deficiency is normally diagnosed with a simple blood test.
Treatment
When a specific cause for testosterone deficiency can be determined, treatment can be focused on that cause. When it comes to the excess pituitary secretion of hormones, for example, medication or surgery might be used to correct the underlying problem.
In cases where no particular cause can be determined, testosterone replacement therapy is the most common treatment option.
Testosterone replacement therapy increases the body's testosterone levels through regular administration of testosterone. This therapy can take several forms:
There are two other types of testosterone therapy that are either not available in the United States or not recommended:
Risks
Before beginning testosterone therapy, individuals should recognize that it is a life-long commitment. Testosterone supplementation leads to a drop in the amount of testosterone that is naturally produced by the body.
Testosterone replacement therapy can also increase a patient's red blood cell mass, reflected in a test called the hematocrit. Therefore, careful tracking of hematocrit levels is important.
