The first sign that a mans hormone level is dropping off is a subtle loss of energy and strength. There is also a depressive change in personality noticed by the wife and friends. Men enter a gray zone, a time they neither understand or wish to talk about.

When there is less testosterone available in the body to do its work, the testosterone target organ response decreases bringing about many changes.

There is great variability in testosterone levels on healthy men so not everyone will experience the same changes to the same extent. Some typical responses to low testosterone levels include:

        - Low libido
        - Emotional, psychological and behavioral changes
        - Loss of muscle strength
        - Increased upper and central body fat
        - Back Pain   
        - Loss of Energy
        - Poor Memory
        - Change in visual acuity
        - Leg Cramps
        - Changes in hair growth and skin quality
