Introduction
Anti-mullerian hormone (AMH) plays a crucial role in understanding a woman’s fertility potential. AMH is produced by the small follicles in the ovaries and serves as a marker of a woman’s ovarian reserve the number of viable eggs left in the ovaries. Women considering pregnancy, whether naturally or through fertility treatments like IVF (In Vitro Fertilization), often undergo an AMH test to determine their fertility status.
This article will explore key aspects of AMH levels, focusing on how they vary by age, their role in fertility, and how they impact IVF outcomes. We will also address common questions about AMH, such as its relationship to egg quality, its significance in conditions like PCOS (Polycystic Ovary Syndrome), and how AMH levels can be improved. We’ll also look at the average AMH levels by age and the AMH levels normal range by age, with an AMH levels by age chart, included for clarity.
What is Anti-Mullerian Hormone (AMH)?
Anti-Mullerian Hormone, or AMH, is a protein hormone produced by ovarian follicles. It is widely used as a biomarker to assess ovarian reserve—the number of eggs a woman has left in her ovaries. A simple blood test, known as the AMH test, measures the amount of this hormone, and the results provide valuable insights into a woman’s reproductive lifespan and fertility potential.
Does AMH Level by Age Predict Egg Quality?
While AMH levels give a good indication of the number of eggs remaining in the ovaries, they do not directly predict the quality of those eggs. Egg quality declines naturally with age, particularly after the mid-30s, even if AMH levels remain within the normal range. This means that a woman could have a high AMH level but still face difficulties conceiving due to declining egg quality. On the other hand, younger women with lower AMH levels might still have good egg quality.
In conclusion, AMH levels are more closely associated with the quantity of eggs, while age remains the primary factor affecting egg quality.
AMH Levels by Age: What is a Good for Pregnancy?
AMH levels vary naturally with age, and understanding what is considered “normal” or “good” is essential for assessing fertility. Below is a general breakdown of AMH levels by age, showing what might be considered normal or indicative of good fertility.
AMH Levels Chart by Age
Age Range | Good AMH Level (ng/mL) | Normal Range (ng/mL) |
Under 25 | 4.1 | 2.5 – 6.0 |
25-29 | 3.5 | 2.0 – 5.5 |
30-34 | 2.8 | 1.5 – 4.5 |
35-39 | 1.5 | 1.0 – 3.0 |
40-44 | 0.9 | 0.5 – 2.0 |
45+ | 0.4 | 0.1 – 0.9 |
How Much AMH is Normal for Pregnancy by Age?
The normal AMH levels by age depend on various factors. Generally, women under 35 with AMH levels above 1.5 ng/mL are considered to have a normal ovarian reserve, while those with levels between 1.0 and 1.5 ng/mL may have diminished ovarian reserve. Women over 40 typically have lower AMH levels, which may impact their ability to conceive naturally or with assisted reproductive technologies such as IVF.
For women in their 20s and early 30s, AMH levels in the range of 2.0 to 4.0 ng/mL are usually considered normal for pregnancy. However, as women age, AMH levels decrease, and by the mid-40s, levels below 1.0 ng/mL are common, reflecting a decline in fertility potential.
What is a Bad AMH Level?
A “bad” or low AMH level typically refers to levels that indicate diminished ovarian reserve. In general:
- AMH levels below 1.0 ng/mL are often considered low, especially for women under 35.
- AMH levels below 0.5 ng/mL may suggest a very low ovarian reserve, which can make it difficult to conceive naturally or through IVF.
Low AMH levels, while not necessarily indicating infertility, may require more aggressive fertility treatments to conceive.
AMH Levels for PCOS by Age: What You Need to Know
Women with Polycystic Ovary Syndrome (PCOS) often have elevated AMH levels due to the presence of a large number of small follicles in the ovaries. While high AMH levels are not typically a direct cause for concern, they can be indicative of the hormonal imbalances associated with PCOS.
For women with PCOS, AMH levels above 6.0 ng/mL are common. In such cases, fertility treatments may need to be adjusted, as women with high AMH levels may have a higher risk of ovarian hyperstimulation during IVF.

What is the Minimum AMH Level for IVF by Age?
There is no strict “minimum” AMH level required for IVF, but low levels can reduce the chances of success. Typically, an AMH level above 1.0 ng/mL is considered favorable for IVF, as it suggests that the ovaries will respond well to ovarian stimulation, leading to the production of multiple eggs for retrieval.
- AMH levels between 1.0 and 3.5 ng/mL are considered optimal for IVF.
- AMH levels below 1.0 ng/mL may indicate poor ovarian reserve, which can lead to fewer eggs being retrieved during IVF.
However, many women with lower AMH levels still achieve successful pregnancies with IVF, though the process may require more cycles or the use of donor eggs.
What are the Causes of Low AMH?
Multiple factors can contribute to low AMH levels, including:
- Age – AMH naturally declines as women age, with the steepest drop occurring after the age of 35.
- Genetics – Some women are genetically predisposed to lower ovarian reserves, even at younger ages.
- Lifestyle Factors – Smoking, poor diet, and environmental toxins can negatively affect AMH levels.
- Medical Conditions – Autoimmune disorders, certain medications, or previous treatments like chemotherapy can reduce ovarian reserve and lower AMH levels.
How to Improve AMH Levels?
While there is no surefire way to increase AMH levels, certain lifestyle changes and treatments may help improve ovarian health:
- Healthy Diet: A diet rich in antioxidants, vitamins, and healthy fats can support ovarian health. Foods like leafy greens, nuts, seeds, and fatty fish are excellent for maintaining hormone balance.
- Exercise: Moderate exercise can improve blood flow to the ovaries and support overall reproductive health.
- Supplements: Some studies suggest that supplements like Coenzyme Q10 (CoQ10) and DHEA (Dehydroepiandrosterone) may help improve ovarian reserve in some women.
- Avoid Smoking and Toxins: Smoking is known to accelerate ovarian aging, so quitting is crucial for maintaining AMH levels.
- Fertility Treatments: For women with significantly low AMH levels, fertility treatments like IVF can still offer hope, and in some cases, egg freezing or using donor eggs may be considered.
AMH Levels by Age for IVF: What You Need to Know
AMH levels are a critical factor in determining a woman’s response to ovarian stimulation during IVF. Women with normal AMH levels by age typically respond better to fertility treatments, as they are likely to produce more eggs.
For example, women under 35 with AMH levels between 2.0 and 4.0 ng/mL generally have a higher success rate with IVF. As AMH levels decline with age, women over 40 with AMH levels below 1.0 ng/mL may face more challenges but can still conceive through IVF with the right ovarian stimulation protocols.

Conclusion
Understanding AMH levels by age is a vital part of assessing fertility potential. While low AMH levels may suggest poor or diminished ovarian reserve, many women with low levels still achieve successful pregnancies with the help of fertility treatments like IVF. Whether you’re trying to conceive naturally or exploring assisted reproduction options, staying informed about your AMH levels and their implications for your fertility journey is crucial.
By consulting with a fertility specialist and taking proactive steps to support your reproductive health, you can better navigate the complexities of fertility and improve your chances of achieving a successful pregnancy.
FAQ:
How To Check Egg Quality In Females?
Egg quality is often evaluated through the AMH test, antral follicle count (AFC) via ultrasound, and sometimes through hormone tests like FSH and estradiol levels.
Can I Get Pregnant At 37 With Low AMH?
Yes, it is possible to get pregnant with low AMH at 37. Natural conception might take a longer time and it may be more challenging. IVF or fertility treatments can be a help, and consulting a fertility specialist is recommended in these cases.
Is High AMH Bad for Fertility?
High AMH can indicate conditions like PCOS, which may affect ovulation. However, it also suggests a good ovarian reserve, which can be favorable for fertility treatment outcomes.
When is AMH highest in the cycle?
AMH levels remain relatively stable throughout the menstrual cycle, so they can be measured at any time, unlike other hormones.
