Men’s Hormones

Men’s Hormones

Testosterone is the primary male hormone. There are enormous consequences of testosterone deficiency or excess on energy, libido, physical and mental condition and performance.

There is a gradual decline in the production of testosterone, about 1-2% per year, beginning in the 30s or 40s, and continuing into older age.  Testosterone depletion results from the combined loss of pituitary and testicular function.

Suppressed testosterone may result from poor diet, nutrient depletion, illness, stress, or toxic effects of medication or environmental toxins.  Alcohol and other recreational drugs, psychiatric drugs, heavy metal toxicity, exposure to insecticides and herbicides, can all be investigated as possible causes of testosterone deficiency.

The range of normal testosterone is wide, 300-1000 ng/dl.  Levels under 300 ng/dl are considered deficient at any age.  A decline in the individual’s testosterone level, even within the normal range, may initiate deficiency symptoms.

Testosterone levels should be measured in men with any of these symptoms.  Testing is best performed in the morning, since testosterone will be higher at that time of day.  Measurements of free or bioavailable testosterone may also be useful, since certain conditions, such as obesity, reduce the amount of testosterone available to the cells.

We measure hormone levels one month after starting therapy, to verify optimal dosage.  Men with testosterone deficiency may respond rapidly and dramatically, often within days.  Physical, mental and emotional symptoms that may have been present for years, can quickly improve.
