Fertility testing can bring up a mix of emotions, especially when the results are unclear or unexpected. If you’ve been told you have low AMH, you might be wondering what that means for your chances of getting pregnant. The good news is that low AMH fertility challenges are more nuanced than they first appear. With the right information and support, you still have a way forward.
What Is AMH?
Anti-Müllerian Hormone (AMH) is a hormone produced by small follicles in the ovaries, each containing an immature egg. Therefore, AMH is used as a marker of ovarian reserve, which refers to the number of eggs left in the ovaries.
An AMH test is a simple blood test that measures this hormone. Unlike some other fertility hormones, AMH levels stay fairly stable throughout your cycle, so the test can be done at almost any time. Higher AMH levels suggest a larger egg supply, while lower levels point to fewer remaining eggs.
How Are AMH Levels Used in Fertility?
Doctors use AMH levels as one piece of the fertility puzzle. It doesn’t account for egg quality or guarantee whether pregnancy will happen. Instead, it gives insight into how the ovaries might respond to treatment.
For example, AMH is commonly used to guide IVF options. If your AMH is lower, your ovaries may produce fewer eggs during treatment. Knowing this ahead of time allows your fertility specialist to adjust your medications and talk through what to expect.
Note that while diminished ovarian reserve means your egg supply is lower than expected for your age, many people with low AMH still ovulate regularly and may conceive naturally or with treatment.
What Is a Normal AMH Level?
AMH levels vary by individual biology and age, so there is no one-size-fits-all number. Still, you can use these general ranges as a guide:
- An AMH level above 1.0 ng/mL is typically considered normal.
- A range of 1.0 to 3.5 ng/mL reflects a robust ovarian reserve.
- Slightly below 1.0 ng/mL may suggest diminished ovarian reserve.
- Anything below 0.5 ng/mL indicates a significantly reduced egg supply.
It’s important to interpret these numbers in context. A lower AMH level doesn’t automatically mean infertility. It simply reflects egg quantity and can’t fully predict your ability to get pregnant.
What Are the Symptoms of Low AMH?
Low AMH usually doesn’t cause noticeable symptoms. Many people only discover it through fertility testing. In some cases, it may be associated with:
- Shorter menstrual cycles
- Irregular periods
- Difficulty getting pregnant
However, these signs are not specific to low AMH. Many people with diminished ovarian reserve have completely regular cycles and no apparent symptoms at all.
What Are Common Causes of Low AMH?
Several factors contribute to lower AMH levels. Some are expected, while others may surprise you:
- Age: This is the most common factor. AMH naturally declines as you get older, though it’s important to note that it can still happen to people in their 20s or early 30s.
- Genetics: Some women are born with a lower egg supply.
- Cancer treatment: Chemotherapy or radiation may affect ovarian reserve.
- Ovarian surgery: Procedures involving the ovaries may reduce egg count.
- Endometriosis: This condition damages the ovarian environment, reducing the number of available eggs.
- Unknown causes: In some cases, a woman’s egg count is low for no clear reason.
What If I Have Low AMH Levels?
A low AMH result may feel discouraging, but it’s not the end of the road. Many options are still available, depending on your goals and timeline. Fertility specialists can help you develop a personalized approach that may include the following:
- Trying to conceive sooner rather than later
- Timing intercourse with ovulation cycles
- Adjusting your medications during IVF to encourage your ovaries to produce as many eggs as possible
- Considering multiple IVF cycles to retrieve more eggs
- Discussing egg freezing if you’re not ready to be a parent yet
Even with low AMH fertility challenges, having a child is still possible. Some people conceive naturally, while others achieve pregnancy through treatment. The most important step is to get a thorough evaluation and create a plan that fits your situation.
