What do your progesterone levels mean?
The short answer
Nobody we follow has said what your progesterone should be. It comes up in the interviews we follow, but never with a number.
For progesterone, the range shifts with cycle phase. Read yours against the range printed on your own report.
A typical lab range is 0.1–25 ng/mL.
Labs print different ranges by sex: about 0.1–25 ng/mL for women and 0–1 for men.

Common questions
What is a normal progesterone level?
The normal range for progesterone depends on cycle phase. Read your number against the range printed on your own report. The quotes on this page say what moves it. Labs print separate ranges for men and women. No physician or research scientist we follow has said how the time of day, stress or sleep changes progesterone. None has said how progesterone differs between men and women either.
What does your progesterone number mean?
Where it sits against the range your own report prints next to it. Nobody we follow has drawn a tighter line inside that range.
What does the progesterone test measure?
The hormone your body releases after ovulation to prepare the uterine lining. Where you are in your cycle decides what it means, so the day of the draw matters.
Why is there no target here?
Because nobody we follow has named a number for progesterone. If that changes, it will be here.
