It is common knowledge that testosterone, the principal male sex hormone, can be reduced with aging male.

Because testosterone is important not only to support male sexual function, but also for the correct functionality of other organs such as bones, muscles, heart and central nervous system, a specific questionnaire was developed to search for any symptoms related to a deficiency of testosterone .

The questionnaire, developed by researchers at the University of Saint Louis(USA), is suitable for men age 40 and older. The questionnaire does not replace in any way the medical examination which remains the essential tool for the evaluation of the patient.

This basic questionnaire can be very useful for men to describe the kind and severity of their low testosterone symptoms.
