Normal Hormone Levels by Age (Women)
Reference ranges for the hormones that shape the menopause transition shift across a woman’s life. Pick a hormone below to see its representative interval by life stage — estradiol and FSH swing most through perimenopause, while testosterone drifts down gradually with age. These are educational reference intervals, not a diagnosis: labs and assays differ, so confirm any result with the clinician who ordered it.

Estradiol reference range by stage
Representative intervals in pg/mL. Ranges vary by lab and assay — confirm with your ordering clinician.
Before puberty
< 15
Reproductive — early follicular (days 1-5)
20-80
Reproductive — late follicular / ovulation peak
100-400
Reproductive — luteal phase
50-160
Pregnancy
Hundreds to > 10,000
Perimenopause
Widely variable (often 30-150, with swings)
Postmenopausal (no hormone therapy)
< 30 (often < 10)
Axis: 0–420 pg/mL. Bars show the representative reference interval per stage.
| Life stage / cycle phase | Estradiol (pg/mL) | Notes |
|---|---|---|
| Before puberty | < 15 | Low until puberty, then rises |
| Reproductive — early follicular (days 1-5) | 20-80 | Lowest point of the cycle |
| Reproductive — late follicular / ovulation peak | 100-400 | Peaks just before ovulation |
| Reproductive — luteal phase | 50-160 | Secondary rise after ovulation |
| Pregnancy | Hundreds to > 10,000 | Rises steadily toward term |
| Perimenopause | Widely variable (often 30-150, with swings) | Erratic highs and lows — hard to read on one draw |
| Postmenopausal (no hormone therapy) | < 30 (often < 10) | Ovarian estradiol production has largely stopped |
