Testosterone Deficiency Syndrome (Hypogonadism)
Testosterone Deficiency Syndrome, or Hypogonadism, is a disorder in which a man's body does not make sufficient 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 occasionally 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, and mental and physical energy.
Symptoms
There are a number of symptoms that are associated with a deficiency in testosterone in men:
Causes
Sometimes, a certain cause for testosterone deficiency might be discovered. An example would be excess secretion of one or more pituitary hormones that then disrupt testosterone production or availability.
In most people, though, no cause for testosterone deficiency can be found. In these circumstances, testosterone replacement therapy is generally an effective treatment.
Effects
Beyond the symptoms that a lot of men experience, testosterone deficiency syndrome can also contribute to the onset or worsening of various diseases.
Diagnosis
Testosterone deficiency is typically diagnosed with a basic blood test.
Treatment
When a specific cause for testosterone deficiency can be determined, treatment can be focused on that cause. In the case of excess pituitary secretion of hormones, for instance, medication or surgery may be used to fix the underlying problem.
In cases where no particular cause can be identified, 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 forms of testosterone therapy that are either not available in the U.S. or not recommended:
Risks
Before beginning testosterone therapy, patients should know that it is a life-long commitment. Testosterone supplementation results in a reduction 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, as shown in a test called the hematocrit. As a result, careful tracking of hematocrit levels is essential.
