One of the most discussed tests in evaluating female fertility in recent years is the AMH (Anti-Müllerian Hormone) test. Many women worry, "My AMH is low, does that mean I can't get pregnant?" Although this hormone provides an idea about ovarian reserve, it is not a direct measure of the probability of pregnancy. In this article, we will discuss what AMH is, how it is measured, and how the results should be interpreted.

What is AMH?

AMH is a hormone secreted by small, immature follicles in the ovaries. This hormone gives an idea about the number of "waiting" eggs in the ovary. It is a biochemical indicator of your ovarian reserve. If the AMH level is high, there are plenty of egg candidates. If it is low, the number of eggs is reduced. For this reason, it is frequently used to predict ovarian response, especially in patients planning IVF.

How is the AMH Value Measured?

The AMH test can be measured in the blood on any day of the menstrual cycle. Unlike other hormone tests (e.g., FSH, LH, E2), the AMH level does not vary much during the monthly cycle, making it a reliable reserve indicator. Values are generally interpreted as follows:

>3.5 ng/mL: High reserve (e.g., in PCOS)
1.5–3.5 ng/mL: Normal reserve
0.5–1.5 ng/mL: Low reserve
<0.5 ng/mL: Significantly decreased reserve

Does AMH Indicate Ability to Conceive?

AMH provides information about the number of eggs, but not directly about their quality. Therefore, low AMH does not always mean that the chances of pregnancy are low. A 30-year-old woman with low AMH may have much better egg quality than a 42-year-old with normal AMH. There are many other factors affecting the chance of pregnancy, such as age, genetic structure of the egg, intrauterine environment, sperm quality, and hormone balance.

What is AMH's Role in IVF Treatment?

In the IVF process, the AMH value is used to predict the ovaries' response to medications. It roughly answers the question "how many eggs can be collected?". Thanks to this, appropriate medication doses are determined, patients at risk of OHSS are recognized early, and protocol strategies are planned for poor responders.

Factors Affecting AMH

Age: It is the most important determining factor. After age 35, AMH begins to decrease every year.
Smoking: Creates a toxic effect on ovarian cells.
Excess weight and stress: Can lower AMH by disrupting hormone balance.
Surgical procedures: Especially endometrioma (chocolate cyst) surgeries can reduce the reserve.

What Can Be Done with Low AMH?

It is wise to plan pregnancy without delay. However, remember that low AMH indicates a decrease in ovarian reserve, not the chance of pregnancy. Thus, there is always a chance of conceiving spontaneously. But if pregnancy is not achieved within 6 months, it would be appropriate to consider IVF. Additionally, treatments to support ovarian reserve (e.g., DHEA, CoQ10) or embryo freezing options can be evaluated.

Conclusion

AMH is an important indicator in evaluating a woman's ovarian reserve. However, it does not determine the chance of pregnancy alone; it must be considered along with age, egg quality, and other factors. AMH is like a "compass indicating ovarian capacity", helping guide the way.
