What is a normal cortisol level for a woman? Women and men compared

Everyone has cortisol. It is made by the adrenal glands, two small glands above the kidneys (MedlinePlus). So the question is not whether women have cortisol. It is whether a normal level is different for a woman, and the honest answer is that the sources used here don’t print separate ranges.

This page covers what does differ between the sexes, why a woman’s blood result can read higher without her free cortisol being higher, and what to check on your own report.

Is there a different normal range for women?

Not in the sources used here. The 2025 review gives one serum range for adults, not one for each sex (Int J Mol Sci, 2025).

That does not mean your lab prints one. MedlinePlus says a test can have separate reference ranges for different groups, and that you should check the range listed on your own report, because labs use different methods (MedlinePlus). If your report lists a range for your sex or age, that one applies.

How cortisol differs between women and men

Studies find differences in how cortisol behaves, even though the ranges aren’t split:

• Output. A 2024 review says men have higher cortisol output, with a higher average peak, lowest point and morning rise, than women before menopause. The peak cortisol rise (the acrophase) increases gradually with age in women but not in men, so there is no longer a difference after menopause (Endocrine Reviews, 2024).
• Daytime pattern. A 2025 review says women before menopause tend to have lower daytime cortisol and a less regular rhythm than men, while differences fade after menopause (Int J Mol Sci, 2025).
• Stress reactions. The same review says women generally show higher cortisol responses to psychosocial stressors than men. That describes how cortisol reacts to a stressor in studies. It is not a lab reference range.
• Menstrual cycle. Studies are mixed. Some find no difference in saliva cortisol across the cycle, and others find higher blood levels in the first half (Endocrine Reviews, 2024).
• Hair. In one study of 256 healthy adults, hair cortisol did not differ between females and males (J Endocrinol Invest, 2026).
• 24-hour urine. A 2026 review lists sex among the things that can influence a 24-hour urine free cortisol result, with body mass index, age, urine volume and sodium intake (J Clin Endocrinol Metab, 2026).

These are group averages. They don’t tell you whether your own level is typical.

Birth control pills, pregnancy and blood cortisol

Most cortisol in blood is attached to a carrier protein called CBG. Only about 5% is free, the active part. Estrogen from oral contraceptives, and the high estrogen of pregnancy, makes the liver produce more CBG, so total cortisol reads higher without more active cortisol (Endocrine Reviews, 2024). A 2024 review, citing a 2007 study, puts the rise in total serum cortisol at about 67% in women who take oral contraceptive pills, with pregnancy causing similar rises, and says tests that measure free cortisol, such as urine and saliva, aren’t affected (J Endocr Soc, 2024).

MedlinePlus also lists pregnancy and birth control pills among the things that can change cortisol levels. So if you use an estrogen-containing pill, or you are pregnant, tell the clinician who reads your result. Don’t stop a pill to prepare for a test unless your prescriber tells you to. The sources used here give no separate blood ranges for pregnancy, so use the range on your report and ask your clinician. See birth control and cortisol and cortisol in pregnancy.

Menopause

The 2024 review says the difference between women and men in the peak cortisol rise is no longer there after menopause. Beyond that, ranges for women after menopause are not printed in the sources used here. Symptoms around menopause, such as tiredness or poor sleep, have many causes, and a cortisol level alone doesn’t explain them. See cortisol and menopause.

Common questions

Do men have cortisol?

Yes. The adrenal glands make cortisol in everyone. The sources used here give one adult serum range and don’t split it by sex.

Do women have cortisol levels that are normally higher?

Not from the ranges. Women before menopause tend to have lower daytime cortisol than men in the studies above. A woman’s total blood cortisol can read higher if she takes an estrogen-containing pill or is pregnant, because of the carrier protein, not because she makes more active cortisol.

What is a normal cortisol level for a woman at 8 a.m.?

One review lists 3 to 23 µg/dL for total serum cortisol at 8 a.m. Labs differ in method, so your report’s range comes first. That range isn’t specific to women.

What to check on your own result

1. The time the sample was taken. A morning value belongs against a morning range.
2. Whether you take estrogen or are pregnant. Tell the clinician who reads it.
3. Which range your report prints, and whether it is for your sex or age.
4. Whether it was total or free cortisol. See free and total cortisol.

A result outside the range may or may not be a problem, and a cortisol test alone can’t diagnose the cause. If you take a steroid medicine, don’t stop or change it. Ask your prescriber. For a morning and later pair, see AM and PM timing.
