For women (before menopause): typically ranges from 15-350 picograms/mL during the cycle, rising to over 1000 during ovulation. For women (after menopause): less than 10 picograms/mL. For men: ranges from 10-50 picograms/mL. Always compare the result with the reference range specified by the laboratory and the phase of the cycle.

Frequently Asked Questions (FAQs)

When should estradiol testing be done during the menstrual cycle? The timing of the test depends on the purpose. To assess fertility and "ovarian reserve," it is often requested on the second or third day of the cycle along with other hormones (such as FSH). To evaluate ovulation, it may be requested around the middle of the cycle. Always follow the doctor's instructions precisely.
What are the causes of elevated estradiol levels in men? It can occur due to obesity (where fat cells produce estrogen), liver diseases, rare testicular tumors, or as a side effect of certain medications. Additionally, low testosterone levels may lead to a relative increase in estrogen.
Does low estradiol mean menopause? Not necessarily. It may decrease years before menopause (perimenopause) or due to other conditions such as excessive exercise, severe weight loss, or premature ovarian failure. Diagnosis depends on age, symptoms, and other hormones like FSH.

Normal Levels

For women (before menopause): typically ranges from 15-350 picograms/mL during the cycle, rising to over 1000 during ovulation.
For women (after menopause): less than 10 picograms/mL.
For men: ranges from 10-50 picograms/mL. Always compare the result with the reference range specified by the laboratory and the phase of the cycle.

Conditions & Notices

Fasting is not usually required, but it is recommended to follow the specific instructions of the physician.
For women of reproductive age, the exact day of the menstrual cycle should be determined when taking the sample, as levels fluctuate significantly throughout the month.
Inform the physician or laboratory about all medications and dietary supplements, especially hormones or birth control pills.
The sample can be taken at any time of the day, but consistency in timing is preferred if the test is being followed up.
