What Is AMH and What Does It Tell You About the Ovaries
Direct Answer
AMH is a hormone used to help estimate ovarian reserve, but it cannot tell you egg quality or confirm a chance of pregnancy from a single value alone. It should be interpreted together with age, ultrasound, antral follicle count, and other health information.
Key Takeaways
- AMH (Anti-Müllerian Hormone) is produced by small follicles in the ovaries and roughly correlates with the estimated number of remaining eggs.
- AMH does not indicate egg quality and cannot directly predict the chance of pregnancy.
- AMH generally declines with age, but individual variation can be large.
- AMH should be interpreted together with an antral follicle count ultrasound and health history by a doctor.
AMH, or Anti-Müllerian Hormone, is produced by cells around small follicles in the ovaries. Blood AMH levels are used to help estimate the approximate remaining egg supply (ovarian reserve), which is one piece of information doctors use in fertility care planning.
However, AMH is only an indicator of quantity, not quality. A high AMH does not always mean the eggs are of good quality, and a low AMH does not necessarily mean pregnancy is impossible. Pregnancy also depends on other factors such as age, uterine health, and male factors.
AMH is often used together with an antral follicle count ultrasound to give a fuller picture of ovarian reserve at that point in time.
Who Should Be Evaluated
People planning fertility evaluation, considering egg freezing, or advised by a doctor to assess ovarian reserve before treatment planning.
General Evaluation or Care Steps
AMH is checked with a blood draw and can be tested on any day of the cycle without fasting. Results are usually interpreted together with ultrasound and health history by a doctor.
Limitations
AMH cannot indicate egg quality, and cannot confirm or rule out a chance of pregnancy from a single number — measured values can also vary slightly between labs.
Risks to Know
The blood draw for AMH is low-risk; some people may have mild bruising at the draw site.
When to See a Doctor
If you want information on ovarian reserve for family planning or considering egg freezing, consult a doctor for appropriate testing and interpretation.
Frequently Asked Questions
Does a low AMH mean I cannot get pregnant?
No. A low AMH only indicates an estimated egg count below average — it does not confirm pregnancy is impossible. Discuss with a doctor for an evaluation alongside other factors.
Do I need to fast before an AMH test?
Generally no fasting is needed, but check with the clinic you are visiting to be sure.
