Estradiol: normal range and what it means
Short answer: The normal estradiol range is 10 – 40 pg/mL for men and 30 – 400 pg/mL for women. In SI units that is about 37 – 147 pmol/L for men and 110 – 1468 pmol/L for women. Labs differ a little, so also check the range printed on your report.

The main estrogen — varies by cycle in women.
Normal range
This marker’s healthy range depends on sex and age.
| Normal range | Men | Women |
|---|---|---|
| Low | < 10 pg/mL | < 30 pg/mL |
| Normal | 10 – 40 pg/mL | 30 – 400 pg/mL |
| High | ≥ 40 pg/mL | ≥ 400 pg/mL |
What it measures
The main form of oestrogen, central to the menstrual cycle and to bone health, and present and necessary in men too. In women the result only means something against the day of the cycle.
What moves it
In women, dominated by cycle phase — the day of the draw matters more than anything else. In men it rises with body fat via conversion from testosterone.
How to bring it into range
Body fat raises it in both sexes, because fat tissue converts testosterone into it. Always record the cycle day alongside the value.
How fast it responds
Days within a cycle, months for a real shift.

Common questions
- What is the normal estradiol range?
- The normal estradiol range is 10 – 40 pg/mL for men and 30 – 400 pg/mL for women. In SI units that is about 37 – 147 pmol/L for men and 110 – 1468 pmol/L for women. Labs differ a little, so also check the range printed on your report.
- What does a high Estradiol mean?
- A value above the reference band means Estradiol is outside the range typical for a healthy adult. A single reading is rarely conclusive on its own — what matters is the trend across draws and the other markers around it, which is why HealthOS reads the whole panel together rather than one number at a time.
- How do I improve my Estradiol?
- Body fat raises it in both sexes, because fat tissue converts testosterone into it. Always record the cycle day alongside the value.
