Testosterone Levels and Treatment Thresholds
This is a medical question, so I'd encourage you to consult a doctor, but here's the general guidance:
Typical Thresholds
- Below 300 ng/dL is commonly considered low (hypogonadism) by most medical organizations like the American Urological Association
- Below 264 ng/dL is another threshold some clinicians use
- Some men feel symptoms even in the 300-400 ng/dL range
Important Nuances
- Symptoms matter as much as numbers - fatigue, low libido, brain fog, mood changes, muscle loss
- Age plays a role in interpretation
- Free testosterone (not just total) should also be checked
- Results can vary by time of day (test in the morning)
Getting Tested
If you're considering this, I'd recommend:
- Labcorp or Quest Diagnostics for blood testing
- Services like Hims, Defy Medical, or Maximus for men's health clinics that specialize in hormone optimization
- Your primary care doctor or an endocrinologist or urologist
Bottom Line
A number alone doesn't always determine treatment - it's the combination of lab values + symptoms that guides decisions.
Please work with a licensed physician before starting any testosterone therapy.
