AMH levels by age: charts and fertility implications

Here at Modern Fertility, we’re hormone obsessed — especially when it comes to AMH. That’s because AMH levels can give us huge insight into our fertility curves and help us make decisions about the future.

Why are your AMH levels important?

AMH stands for anti-Mullerian hormone — the hormone produced by the granulosa cells surrounding your follicles (the little fluid-filled sacs in your ovaries that house and release eggs).

Studies have shown that AMH is the most reliable marker of ovarian reserve — or how many eggs you have. Higher AMH may be a sign that you have a higher egg and follicle count, and lower AMH may be a sign that you have a lower egg and follicle count.

Your AMH can also help you estimate your chances at success for assisted reproductive technology (ART) procedures like in-vitro fertilization (IVF) and egg freezing — and when you might enter menopause.

What are normal AMH levels by age and how can they change over time?

Every person with ovaries is born with 1-2 million eggs — enough to populate the entire city of Dallas, TX. Some disintegrate before puberty and about 1,000 leave the body each month until menopause, when egg count and AMH drop down to zero. 

Studies show that egg count begins to significantly diminish around age 25, more rapidly around 30, and then even more steeply around 35. As egg count lowers, so does AMH.

But the word “typically” is key here: Every individual is totally unique — your egg count and AMH may lower at a different rate. Measuring your level over time can help you track changes and predict when menopause onset might happen for you.

What can normal AMH levels tell you?

No hormone test, including an AMH test, can guarantee pregnancy or confirm infertility. Think of it like a cholesterol test — while knowing your cholesterol level can’t tell you whether or not you’ll have a heart attack, it can help you track changes over time and inform convos with your doctor.

That said, if your AMH test results come back at a level expected for your age, there’s a good chance that you’ll be able to retrieve a higher number of eggs in preparation for procedures like IVF or egg freezing. It’s also likely that you’ll reach the onset of menopause around age 51 (the average age).

To sum it up: AMH isn’t a crystal ball that can look into your reproductive future, but it is the most reliable marker for understanding your unique fertility curve.

What can low AMH levels tell you?

Women with lower AMH for their age are likely to have a shorter reproductive window (i.e., the time between the start of periods and the onset of menopause) than women with normal AMH for their age.

According to Prof. Scott Nelson, who’s considered one of the leading experts on AMH, “When women enter menopause at an earlier age, it impacts their total fertility across their lifespan and potentially their ability to complete their desired family size.”
