The number arrives in your inbox, and suddenly, your heart skips a beat.
You've done the research. Maybe you're curious about egg freezing, or you've been trying to conceive for a few months. The AMH testing seemed like the easiest way to get answers. One blood draw, one number, and total clarity, right?
But now you're looking at that result. Maybe it's 1.2 ng/mL or 3 ng/mL, and you're more confused than ever. Is it "good"? Why does a forum post say your number is great, while another says it's a crisis?
Here’s the truth: AMH is a single piece of a very big puzzle. It provides info, but it isn't a final verdict. At King Square Fertility, we don't treat you like a lab value. We use the ovarian reserve test to help paint a full picture of your health.
Anti-Mullerian hormone, or AMH, is a hormone produced by the cells surrounding the eggs in your ovaries. Because AMH levels reflect the number of developing follicles, they give insight into your ovarian reserve, or how many eggs you may still have.
For this reason, AMH is commonly used as an ovarian reserve test. It helps estimate egg quantity, but it doesn’t provide information about egg quality or guarantee your ability to conceive naturally.
Another reason AMH testing is widely used is its convenience. Unlike many other hormones that change throughout your cycle, AMH levels remain relatively stable. This means the test can be done at any time, without needing to time it to a specific day.
If AMH can’t predict whether you’ll get pregnant this month, why do we rely on it? The answer lies in planning for the future. When a specialist at a clinic like King Square Fertility looks at your AMH, they are usually looking for two things:
While a low result can feel startling, it’s simply a tool that lets us tailor a medical plan to your body. It helps us determine the right medication dosage so your journey is as safe and effective as possible.
AMH levels change over time and are closely linked to age. In women, AMH begins to rise during the teenage years, reaches its peak around the mid-20s, and then gradually declines as part of the natural aging process.
AMH is measured in nanograms per millilitre (ng/mL). While there’s some variation in how experts define ranges, general guidelines are often used.
To give a general sense of how levels may shift with age, here are approximate values on the lower end of the expected range:
Levels between 1.0 and 3.0 ng/mL are considered average. Levels below 1.0 ng/mL are typically described as low, and levels around 0.4 ng/mL may be very low.
It’s important to note that many women with low AMH conceive naturally every day. It simply means that if you require assisted reproduction, your ovaries might produce fewer eggs during a treatment cycle.
In contrast, AMH levels of 3.5-4.0 ng/mL suggest a higher egg supply. While this can be a positive sign, very high levels are sometimes associated with conditions such as Polycystic Ovary Syndrome, or PCOS, as noted in the Canadian Medical Association Journal.
Your specialist will look at this alongside your cycle history to ensure everything is balanced.
In recent years, the rise of at-home testing kits has made AMH very accessible. While knowledge is power, these kits often lack the human context needed to understand the results. A colour-coded "red" or "green" result can cause unnecessary stress or false confidence.
As stated earlier, AMH levels don’t accurately predict your chances of getting pregnant. You’re so much more than a lab value, and your potential to grow a family involves many factors that a blood draw simply can’t see.
At King Square Fertility, we use AMH as a starting point. To understand your reproductive health, we look at several pieces of the puzzle together:
Yes. A low AMH level means you have fewer eggs remaining, but it doesn’t mean you’re not ovulating or that you can’t conceive. Many women with low reserves achieve healthy pregnancies naturally.
AMH levels naturally decline as we age and cannot be significantly increased.
However, focusing on overall health, such as managing stress and balanced nutrition, supports the health of the eggs you do have.
Not necessarily. While it indicates a large egg reserve, it doesn't guarantee quality or ease of conception. In some cases, very high AMH can be a sign of PCOS, which may require specific support to regulate ovulation.
For most women, one AMH test provides a useful baseline. Repeating it every few months is rarely necessary unless you're actively monitoring response to treatment. AMH declines gradually over time, but frequent testing doesn't change the trajectory.
Information is a gift, but only when it’s accompanied by support. If your AMH results have left you feeling uncertain, the best thing you can do is speak with a professional who can provide the context you deserve.
We encourage you to speak with your family doctor about a referral to a fertility specialist.
Once you have a referral, King Square Fertility is here to welcome you. Whether you’re in Markham or anywhere in the Greater Toronto Area, we’re ready to help you turn that single number into a clear, hopeful plan for your future.
