What’s the average testosterone level in men?
“Average testosterone” depends on age and on how it’s measured (typically a blood test for total testosterone, often reported in ng/dL or nmol/L). In general, total testosterone peaks in early adulthood and declines gradually with age.
If you share the age range (for example, teens, 20s, 40s, older adults) and the unit you’re seeing (ng/dL vs nmol/L), I can help interpret what “average” means for that group.
What’s the average testosterone level in women?
Women also have measurable testosterone, but at much lower levels than men. Like men, the “average” varies by age and lab method. If you tell me the unit and age, I can translate and place your value into a typical range.
Total testosterone vs free testosterone: which one is usually “average”?
Most “average testosterone” talk uses total testosterone from a morning blood draw. Free testosterone (the biologically active fraction) can differ even when total testosterone looks similar, especially when sex-hormone-binding globulin (SHBG) is high or low. If you have your SHBG or free testosterone result, that can change how average ranges are interpreted.
Why your testosterone might differ from the “average” (even with normal health)
Common reasons include:
- Timing of the test (testosterone is highest in the morning)
- Illness, poor sleep, or acute stress
- Obesity (often linked with lower testosterone)
- Some medications
- Lab-to-lab differences in reference ranges
If my testosterone is below average, what’s the next step?
Clinicians usually look for:
- Symptoms consistent with low testosterone
- Repeating the test (often two morning measurements)
- Checking related labs (commonly SHBG, LH, FSH, prolactin, sometimes iron studies), depending on the situation
If you paste your testosterone value, unit, age, and whether it was morning/fasting, I can help you interpret how far it is from typical ranges.
