What are normal estrogen and progesterone levels for a 37 year old woman?

Range: There is a wide range of normal depending on where you are in your cycle. The menstrual cycle is a good barometer of normal hormonal function. If your periods are normal and timely, then your hormone levels should be fine.

It varies: It depends on what day in the menstrual cycle that your are on and whether ovulation(progesterone secretion thereafter) occurs, if at all. Many 37 year old women are not ovulating every month due to age.

Let me explain: The normal range of estrogen varies depending upon the patient's age. A female aged 30 to 39 will average a level of 210 pg/ml. Progesterone levels vary considerably from cycle to cycle and woman to woman. The middle of the second half of the cycle Progesterone in a non-pregnant patient is 8 to 10, but can be high as 20 ng/ml.
