If you’ve started exploring your fertility or have visited a fertility clinic, you’ve likely heard about Anti-Müllerian Hormone (AMH). AMH is one of the most commonly measured hormones during fertility assessments because it provides valuable information about ovarian reserve.
However, AMH is also one of the most misunderstood fertility markers. A low AMH level does not necessarily mean you cannot become pregnant, and a high AMH level does not guarantee fertility.
Understanding what AMH measures—and what it doesn’t—can help you make more informed decisions about your reproductive health.

Anti-Müllerian Hormone is produced by small follicles within the ovaries.
These follicles contain immature eggs, and the amount of AMH in the bloodstream provides an estimate of ovarian reserve, which refers to the number of eggs remaining in the ovaries.
Because AMH levels change relatively little throughout the menstrual cycle, they can usually be measured at any time.
Healthcare providers often include AMH testing as part of a broader fertility evaluation.
An AMH test provides information about egg quantity, not egg quality.
Generally:
However, AMH cannot determine:
Your age, overall health, ovulation, partner’s fertility, and many other factors also influence fertility.
Several factors may influence AMH levels, including:
Age is the strongest predictor of AMH.
Women are born with all of the eggs they will ever have, and ovarian reserve naturally declines over time. AMH levels typically decrease as women get older.
Women with PCOS often have higher-than-average AMH levels because they typically have a larger number of small ovarian follicles.
High AMH alone does not diagnose PCOS, but it may provide additional information when considered alongside symptoms, hormone tests, and ultrasound findings.
Some medical treatments, including chemotherapy or ovarian surgery, may reduce ovarian reserve and affect AMH levels.
Your healthcare provider can explain how your medical history may influence your test results.
Many websites claim that certain diets, supplements, or exercise programs can significantly increase AMH levels.
At present, there is limited scientific evidence that lifestyle changes can meaningfully increase ovarian reserve or permanently raise AMH levels.
However, maintaining good overall health remains important for reproductive wellness.
Healthy habits include:
These habits support your overall health and may improve fertility outcomes, even if they do not directly increase AMH.
AMH is a useful tool, but it is only one piece of the fertility picture.
Healthcare providers also consider:
For this reason, an AMH result should always be interpreted alongside other clinical information.
Understanding your menstrual cycle is an important part of reproductive health.
Tracking cycle length, ovulation patterns, and menstrual changes can help you recognize trends and provide useful information to discuss with your healthcare provider during fertility assessments.

Anti-Müllerian Hormone is an important marker of ovarian reserve, but it does not tell the complete story about fertility.
While AMH can help healthcare providers estimate the number of eggs remaining in the ovaries, it cannot predict whether pregnancy will occur naturally or guarantee the success of fertility treatment.
If you’re concerned about your fertility or are considering pregnancy, speaking with your healthcare provider can help you understand whether AMH testing is appropriate and how the results fit into your overall reproductive health.
AMH measures ovarian reserve, or the estimated number of remaining eggs in the ovaries. It does not measure egg quality or predict natural fertility on its own.
Yes. Many women with low AMH conceive naturally. Fertility depends on many factors, including age, ovulation, overall reproductive health, and sperm quality.
Not necessarily. Higher AMH usually indicates a larger ovarian reserve, but it does not guarantee pregnancy. Women with PCOS, for example, often have high AMH while still experiencing ovulation problems.
Not always. AMH testing is most useful when recommended by a healthcare provider as part of a fertility evaluation or treatment plan.
