Best to have the well trained doc Look at LH,FSH and Total T levels to make proper diagnoses.
Other reasons.
Klinfelters syndrome--both with XXY chromosomes and therfore lower T levels
Any trauma to testicles (induces primary hypo)
Any trauma to head (induces secondary)
Radiation treatment to the above areas
And lets not understate LIFESTYLE bad food, seditary lifestyle, heavy alcohol use (lowers T big time). Studies have also showed obese men with an unhealthy BMI have 50% less testosterone then a man of healthy weight. Hope this helps your research.
