AMH: What to Know About Anti-Mullerian Hormone
Alex Myron
If you’ve started exploring fertility testing or treatment, you’ve likely encountered the term “AMH” in conversations with your healthcare provider.
Anti-Müllerian Hormone (AMH) testing has become a cornerstone of fertility assessment, but understanding what your results mean—and what they don’t mean—can feel overwhelming. At Open Fertility, we believe that knowledge is empowering. That’s why we’re breaking down everything you need to know about AMH testing in clear, straightforward terms, so you can make informed decisions about your fertility journey.What Is AMH?
Anti-Müllerian Hormone (AMH) is a protein produced by the small follicles in your ovaries. Think of these follicles as tiny sacs that contain your eggs. The more follicles you have, the higher your AMH level will be. Essentially, AMH serves as a window into your ovarian reserve—the number of eggs remaining in your ovaries. Unlike other hormones that fluctuate throughout your menstrual cycle, AMH levels remain relatively stable, making it a reliable marker that can be tested at any time during your cycle.Why AMH Testing Matters
Your AMH level provides valuable insight into several aspects of your fertility: Ovarian Reserve Assessment: AMH helps estimate how many eggs you have left. While you’re born with all the eggs you’ll ever have, this number naturally declines with age. AMH testing gives us a snapshot of where you stand. At your consult, your provider will test your AMH levels to better understand what treatment options are available for you. Treatment Planning: If you’re considering IVF, your AMH level helps your fertility team predict how your ovaries might respond to stimulation medications and plan treatment accordingly. Egg Freezing Decisions: For those considering egg freezing, AMH testing can help determine the optimal timing and expected outcomes of the procedure. Our egg calculator can also help you understand potential outcomes based on your age and individual factors. Timeline Considerations: While AMH doesn’t predict when you’ll reach menopause, significantly low levels may suggest that time may be a more pressing factor in your family-building plans.Understanding Your AMH Results
AMH is measured in nanograms per milliliter (ng/mL) or picomoles per liter (pmol/L). Here’s what different ranges typically indicate: High AMH (above 3.0 ng/mL): This suggests a good ovarian reserve; however, very high levels may indicate potential PCOS (Polycystic Ovary Syndrome). Normal AMH (1.0-3.0 ng/mL): This range indicates a typical ovarian reserve for your age group. Low AMH (0.3-1.0 ng/mL): This suggests diminished ovarian reserve, meaning fewer eggs remain. Very Low AMH (below 0.3 ng/mL): This indicates significantly diminished ovarian reserve. *It’s important to remember that these ranges can vary between laboratories and can vary from month to month or be falsely (temporarily!) deflated if you’ve been on hormonal birth control for a long period of time. Your results should always be interpreted in the context of your age, overall health, and fertility goals.What AMH Can’t Tell You
While AMH testing is incredibly valuable, it’s important to understand its limitations: Egg Quality: AMH only measures quantity, not quality. You could have a lower AMH but still have high-quality eggs that lead to successful pregnancies. Natural Conception: AMH doesn’t predict your ability to conceive naturally. Many people with low AMH go on to have successful pregnancies without intervention. Pregnancy Success: A higher AMH doesn’t guarantee pregnancy success, just as a lower AMH doesn’t rule it out. Exact Timeline: AMH can’t tell you precisely when your fertility will decline or when menopause will occur.AMH and Age: What to Expect
AMH levels naturally decline with age, but this decline isn’t uniform for everyone. Some women maintain higher levels longer, while others experience earlier declines. Here’s what’s typically expected:- 20s: AMH levels are generally at their highest
- 30s: Gradual decline begins, with more noticeable changes after 35
- 40s: More significant decline as menopause approaches
How AMH Testing Fits Into Your Overall Fertility Assessment
AMH testing is typically part of a comprehensive fertility evaluation that may include other hormone tests, ultrasounds, and partner evaluation if applicable. This holistic approach helps create a complete picture of your fertility status. At Open Fertility, we’ve streamlined this process to be as efficient and accessible as possible. Rather than requiring multiple separate appointments, we coordinate your testing to minimize the time and cost involved while ensuring you receive thorough care.The Emotional Side of AMH Results
Receiving your AMH results can bring up a range of emotions. Whether your levels are higher or lower than expected, it’s normal to feel anxious, relieved, confused, or overwhelmed. Remember that these numbers, while informative, don’t define your worth or determine your entire fertility future. Many of our patients find it helpful to process their results with our care team, who can explain what the numbers mean in the context of your individual situation and goals. We’re here to support not just the medical aspects of your fertility journey, but the emotional components as well.Making AMH Work for You
