Age Tracker
Check Your Hormonal Age in Seconds
Enter your chronological age and total testosterone level to estimate your “hormonal age” – how your endocrine system compares to population averages. See if your hormones are aging faster or slower than you are.
Enter your actual age in years (18–80).
Enter your most recent total testosterone level (50–2000 ng/dL).

Testosterone Reference Ranges by Age
Population averages for total testosterone by age group. These ranges are based on clinical data and help contextualize your results.
| Age Group | Average Total T (ng/dL) | Normal Range (ng/dL) | Decline from Peak |
|---|
Clinical Note: Testosterone levels naturally decline with age at approximately 1% per year after age 30. Individual variation is significant – these are population averages only.
How Hormonal Age Is Calculated
Your hormonal age is estimated by comparing your testosterone level to age-specific population averages. Here’s how the calculation works.
Population Data
We use established reference ranges from large-scale clinical studies to determine average testosterone levels for each age group.
Comparison
Your testosterone level is compared to the age-specific average. If your level matches a different age group’s average, that becomes your estimated hormonal age.
Percentile Ranking
Your position within the normal distribution for your age group is calculated, showing where you fall compared to other men of the same age.
Clinical Context
This tool is for educational purposes only. A hormonal age that differs from your chronological age may warrant clinical investigation.
Medical Disclaimer: This hormonal age tracker is for educational and informational purposes only. It does not provide a medical diagnosis and should not replace professional medical advice. Testosterone levels vary significantly between individuals, and a single testosterone measurement does not define your health status. Always consult your physician or a qualified healthcare provider for proper evaluation and interpretation of your hormone levels.
