The American Association of Clinical Endocrinologists says "Hypogonadism is defined as a free testosterone level that is below the lower limit of normal for young adult control subjects. Previously, age-related decreases in free testosterone were once accepted as normal. Currently, they are not considered normal. Patients with low-normal to subnormal range testosterone levels warrant a clinical trial of testosterone."[31]

I have seen the original document.
Go to a chronic fatigue specialist perhaps, charged with this, note all other bloodwork is OK, and maybe he will prescribe you testosterone??
