Getting an anti-Müllerian hormone (AMH) result back can feel confusing, and a lower-than-expected number can feel alarming too. One number never tells your whole story, and an AMH result means the most when your doctor looks at it alongside everything else about you.
At MCRM Fertility, we treat every person as an individual and as a whole person, so your AMH result will always be considered in the context of your age, health, history, and goals.
What AMH (Anti-Müllerian Hormone) Measures
AMH is a hormone made by granulosa cells in small, early-stage follicles, the fluid-filled sacs in your ovaries where eggs develop. Because AMH comes from follicles smaller than 8 mm, your AMH level reflects your ovarian reserve, meaning the number of eggs your ovaries have remaining.
Keep in mind that AMH measures egg quantity and doesn’t measure egg quality. Your AMH level also stays fairly steady throughout your menstrual cycle, so your provider can order the test on any day, although hormonal birth control can lower AMH and may affect your result, according to the American Society for Reproductive Medicine (ASRM).
What Low, Normal, or High AMH Hormone Levels Generally Mean
AMH levels naturally decline with age, so the same number can mean something different at 28 than at 40. Normal ranges also vary from one lab and testing method to another, which is why your doctor will interpret your result with your age and lab in mind.
In the research ASRM reviewed, levels between 1.0 and 3.5 ng/mL were treated as typical, and levels below 1 ng/mL were treated as low. Your result will generally fall into one of three groups:
- A lower-than-expected AMH level for your age may point to diminished ovarian reserve, and your doctor will confirm the finding with other tests.
- An AMH level in the expected range for your age suggests your ovarian reserve is in line with others your age.
- A higher-than-average AMH level can be one of the signs doctors look at when considering polycystic ovary syndrome, now also called polyendocrine metabolic ovarian syndrome (PCOS/PMOS), since PCOS/PMOS involves a higher number of small follicles. You can learn more about PCOS/PMOS and fertility whenever you’re ready.
What AMH Doesn’t Tell You
AMH doesn’t predict whether you can get pregnant without fertility treatment. In studies ASRM reviewed, women with low AMH levels had similar pregnancy rates over time as women with normal levels, and that’s true of follicle-stimulating hormone (FSH), another ovarian reserve marker, as well.
AMH is an important part of the picture, and it works best alongside your age, an antral follicle count on ultrasound, and your overall health. AMH declines before FSH rises, which makes AMH the more sensitive marker, and your doctor may also check FSH and estradiol if your AMH is very low.
You may wonder how low is too low. ASRM’s guidance states that a low AMH level shouldn’t be used to refuse treatment, and while very low levels can mean fewer eggs during IVF, a low result is a reason to plan carefully with your doctor and explore every option available to you. If your result is lower than expected, our team can walk you through options for diminished ovarian reserve.
How Your AMH (Anti-Müllerian Hormone) Result Is Used in Fertility Treatment
AMH, together with an antral follicle count, helps predict how your ovaries will respond to stimulation medication during in vitro fertilization (IVF) or egg freezing. Your care team will use your result to choose a medication protocol and dosage that fits your body, helping you get the most from each cycle.
Your AMH level is also part of the bigger picture of your egg quality and quantity. Whether you’re thinking about egg freezing, planning IVF, or simply learning about your fertility through fertility screening, your doctor will help you decide on next steps based on your own plans and timeline.
Questions to Ask About Your Own Results
Bringing a few questions to your appointment can help you leave with clarity and a plan. Consider asking your doctor:
- How does my AMH result compare with what’s expected for my age and your lab’s range?
- Do you recommend an antral follicle count, FSH, or other follow-up testing?
- How does my result affect the timing of any treatment I’m considering?
- If I’m planning IVF or egg freezing, how will my AMH shape my medication protocol?
- Which next steps make sense based on all of my results together?
