What the research says about these symptoms
The symptoms above are the core diagnostic criteria for male hypogonadism as defined by the Endocrine Society and multiple guidelines. The gold standard is a blood test, but symptoms matter. Men with labs in the "low-normal" range who have 5+ of these symptoms often benefit from treatment as much as men with clearly low testosterone.
What to do with your score
Low (0-14): Symptoms don't strongly suggest low testosterone. Focus on sleep, training, nutrition, and stress management first. See our increase testosterone naturally guide.
Moderate (15-29): There's a meaningful chance your testosterone is in a suboptimal range. A blood panel is worth it to establish baseline. Address lifestyle fundamentals alongside.
High (30-44): Pattern strongly suggests clinically low or borderline testosterone. Get comprehensive lab work done, total and free testosterone, SHBG, estradiol, LH, thyroid.
Very high (45+): Pattern consistent with significant hypogonadism. Don't delay getting tested.
What blood tests matter
Don't just test total testosterone, it's only part of the picture. A proper men's hormone panel should include:
- Total and free testosterone
- SHBG (sex hormone-binding globulin)
- Estradiol (sensitive LC-MS/MS assay)
- LH and FSH
- PSA (if over 40)
- Comprehensive metabolic panel, CBC, lipids, thyroid
See our complete TRT guide and 10 signs of low testosterone for deeper context.
Why you might have low T
Common drivers:
- Age (testosterone drops 1-2% per year after 30)
- Chronic sleep deprivation
- Obesity and visceral fat
- Undiagnosed sleep apnea
- Chronic stress and cortisol
- Low vitamin D
- Heavy alcohol use
- Certain medications (opioids, SSRIs, corticosteroids)
- Genetic / congenital factors
- Thyroid dysfunction
A proper blood panel + provider consultation identifies which factors apply to you.
