What Is HYPOGONADISM And How Is It Diagnosed?

Male hypogonadism is a clinical condition in which the testes do not produce androgen (testosterone).  In order to diagnose hypogonadsim, a male should be experiencing (1) symptoms associated with a deficiency, as well as (2) have a laboratory finding of serum testosterone below accepted levels. [i]

Symptoms and Signs of Hypogonadism:  Suggestive symptoms of low T include, but are not limited to:

  • Low libido;
  • Erectile dysfunction;
  • Decreased muscle mass and/or strength;
  • Increased body fat;
  • Decreased bone density;
  • Loss of energy/fatigue;
  • Sleep problems;
  • Depression[ii]

The problem with associating these symptoms with low T is that many of these symptoms occur in other conditions or are physiologically associated with the aging process itself.  Accordingly, these symptoms should be corroborated with a laboratory diagnosis of low T.

Laboratory Diagnosis:  According to the Mayo Clinic, a normal reference range of total T levels in adult men over the age of 19 years is 240-950 ng/dl.[iii] Male hypogonadism results from low secretion of T and is generally characterized as concentrations of total T below 240 ng/dl (< 240 ng/dl).  However, laboratory testing of T levels can have reliability issues and can vary wildly based upon a subject’s pre-test activities.  T levels are subject to variation, which can lead to misclassification. Exercise, diet, illness, certain medications, and even the time of day can all have an influence on T levels.  In fact, research has shown that T levels can vary considerably between morning and afternoon as much as an average of 50%[iv],[v]So for example, if a man had his T levels checked in the morning, when they are generally the highest, and had levels of 450 ng/dl, which is well within the normal range, it is entirely possible that his T levels could experience a normal drop to below 225 ng/dl later in the afternoon, falsely indicating he has hypogonadism.  As such, T levels are a relatively crude guideline and should not be used alone in diagnosing and treating hypogonadism. Rather, in addition to low T levels, men should have clinical symptoms mentioned above.
