Introduction
The normal reference range for estradiol is as follows: follicular phase, 92–275 pmol/L; ovulatory phase, 734–2200 pmol/L; luteal phase, 367–1100 pmol/L; and postmenopausal, <100 pmol/L. Estradiol levels vary among women and fluctuate throughout the menstrual cycle; the magnitude of these fluctuations differs from person to person.
In daily life, many women undergo estrogen testing due to physical discomfort. They often wish to understand what constitutes a normal estrogen level. So, what is considered a normal estrogen level?
What Is Considered a Normal Estrogen Level?
The normal reference range for estradiol (E2) varies by menstrual phase: • Follicular phase: 92–275 pmol/L • Ovulatory phase: 734–2200 pmol/L • Luteal phase: 367–1100 pmol/L • Postmenopausal: <100 pmol/L Estradiol levels differ among women and fluctuate throughout the menstrual cycle; the magnitude of these fluctuations varies from person to person. In clinical practice, laboratories may use different assay methods, leading to variations in reference ranges. Therefore, if your test result shows a low estrogen level, do not immediately become anxious or alarmed. Interpretation of estrogen levels must be integrated with the patient’s menstrual cycle phase and overall health status to determine whether the value is truly abnormal. Please consult your physician promptly upon receiving your results.
Estrogen is a hormone secreted primarily by the ovaries in women. It plays vital physiological roles—not only in promoting and maintaining female reproductive organs and secondary sexual characteristics, but also in regulating endocrine, cardiovascular, and metabolic systems, as well as supporting bone growth and maturation.
Regarding daily diet, it is advisable to limit intake of spicy and stimulating foods—such as chili peppers, Sichuan peppercorns, raw garlic, and baijiu (Chinese distilled liquor). All fruits are permissible, but consumption should remain moderate. We hope this information is helpful to you!
