Understanding human fertility is an essential part of every person’s overall health. Anti-Müllerian hormone (AMH) has emerged as one of the most reliable indicators for knowing the ovarian reserve, that “number of eggs” that can influence the chances of pregnancy over time. For this reason, knowing how to correctly interpret the values of this hormone has become an essential tool, both for those who want to have children soon and for those who seek to plan for the long term.
This topic is especially relevant because fertility is not limited only to the moment of trying to get pregnant. It is a reality that changes over time and varies from person to person. Knowing normal AMH values not only allows you to assess reproductive health, but also to better understand how your body works and what options exist for the future.
Now, what is really considered a normal value of the anti-Müllerian hormone? Understanding these numbers and their meaning is key to making informed decisions about fertility at every stage of life.
What is considered a “normal” AMH value?

The range of normal values for anti-Müllerian hormone depends on age and individual circumstances. Generally speaking, AMH levels that are between 2 and 4 ng/mL are considered normal for a woman of reproductive age. However, these ranges are not rigid and can change depending on the clinical context and the laboratory performing the test.
Here’s a basic breakdown of what each level can indicate:
- High AMH (> 4 ng/mL): An elevated AMH level may suggest the presence of a greater number of follicles in the ovaries. In some cases, these high values are linked to polycystic ovary syndrome (PCOS), a condition that affects ovulation. Although a high number can be interpreted as a good ovarian reserve, it is important to consider other factors before drawing conclusions.
- Normal AMH (2 – 4 ng/mL): In this range, the ovarian reserve is considered adequate for a woman of childbearing age. The chances of conceiving are good, but as always, it is essential to supplement this information with other medical tests to assess reproductive health in its entirety.
- Low AMH (< 2 ng/mL): A low AMH level indicates a decrease in ovarian reserve. This does not necessarily mean that it is impossible to achieve pregnancy, but it may suggest that the number of eggs is limited. It is common to find these values in women over 35 years of age, as the ovarian reserve decreases with age.
How do AMH levels vary with age?
Age is a crucial factor that influences AMH levels. In young women, it is common to find higher levels, while over time, these tend to decrease. Here’s an overview of how AMH can behave at different stages of life:
- Between 20 and 30 years old: AMH levels are usually higher at this stage, indicating a good number of eggs available. This not only suggests a healthy ovarian reserve, but also a greater chance of conceiving naturally.
- Between 30 and 35 years old: AMH values begin to decrease gradually. Although it is still considered that there is a good ovarian reserve, it may be a good time for those who want to plan for the future or consider egg preservation.
- From the age of 35: It is common to observe a more significant drop in AMH levels, reflecting the reduction in the number of eggs. This does not imply an impossibility of pregnancy, but it can be indicative of the need to evaluate alternatives, especially if there is an interest in postponing motherhood.
How to interpret the results of the AMH?
The AMH test must be interpreted by a specialist, as this hormone is only one piece of the complex fertility puzzle. Normal values may vary slightly depending on the laboratory, as each one manages its own reference parameters. Therefore, it is essential to have the right medical guidance to understand what the results mean in each particular case.
In some contexts, a low AMH level might suggest the possibility of early menopause, while a high level may indicate the presence of polycystic ovaries. In any case, the correct interpretation will allow you to design a personalized plan to optimize reproductive health.
When is it necessary to monitor AMH levels?
The evaluation of anti-Müllerian hormone is not a test that is performed routinely, but it is especially relevant in certain situations. For example, if there is a family history of early menopause, difficulties conceiving, or if you want to postpone motherhood, regular follow-up can provide useful information.
In addition, in fertility treatments, measuring AMH allows you to adjust the doses of ovarian stimulation drugs and plan appropriate strategies for each case. In this sense, AMH becomes an ally to personalize the therapeutic approach.
Today, many people want to understand their fertility in order to make future decisions, and in this context, AMH is an invaluable tool. Knowing normal values and what factors can alter them allows you to act with greater security and clarity, making each step on the road to motherhood well-founded.
