A quick disclaimer
Zoyra's AMH Calculator is intended for educational and informational purposes only. It compares your AMH result with age-specific values published in Seifer et al. (2011).
These comparisons are not a diagnosis of diminished ovarian reserve, infertility or any other medical condition. AMH alone cannot determine your individual chances of conceiving, the quality of your eggs or the outcome of fertility treatment.
The calculator does not replace medical advice. We recommend discussing your results with a qualified fertility specialist, who can interpret them alongside your medical history, other investigations and individual circumstances.
Your AMH level compared with your age
Enter your age and AMH result above, then select "Compare my AMH" to see your comparison.
Your fertility journey deserves support. What if your employer could help?
Egg freezing, embryo freezing and other fertility treatments can involve substantial costs. Employer support could make access to care easier. Zoyra is developing a fertility and family-building benefit for workplaces. Tell us where you work and we will take the conversation from there.
Understanding your AMH is one step. Getting the right fertility support is another.
There's no obligation, and suggesting Zoyra doesn't mean your employer has committed to offering the benefit.
How AMH levels change with age
The lines show the published median and mean AMH for each age in Seifer et al. (2011). They describe groups of women, not how any individual's AMH will change in the future.
Chart summary: Published median AMH: 3.4 ng/mL (Age 24) → 0.0 ng/mL (Age 50).
Where mean minus 1 SD falls below zero, the band is drawn from 0: the statistical lower bound is below the biologically meaningful measurement range. AMH values were skewed, so this band is not a percentile range, normal range or clinical reference range.
Reference values at older ages are based on smaller study groups and may be less statistically stable.
Source: Seifer DB, Baker VL, Leader B (2011), Fertility and Sterility 95(2):747–750, Table 1. Values are the published median, mean and standard deviation for each year of age, shown without smoothing or modification.
The age-specific AMH reference values used in this calculator come directly from Table 1 of Seifer et al. (2011), a retrospective study of 17,120 women aged 24–50 attending fertility centres in the United States. The table reports the observed median, mean and standard deviation for each single year of age.
AMH values were measured using a laboratory-developed assay, and results obtained using other laboratory methods may differ. The study population may not represent the general population.
AMH distributions were skewed, so the median is presented as the primary descriptive comparison. These results are not clinical diagnostic thresholds and cannot establish an individual's fertility potential.
Data limitations and source attribution
- The underlying study (Seifer et al., 2011) looked at AMH in 17,120 women aged 24 to 50 attending fertility centres in the United States. People attending fertility clinics may not represent the general population.
- The values shown are the study's published year-by-year median, mean and standard deviation from Table 1.
- AMH values were skewed rather than normally distributed. Mean ±1 SD is shown only as a descriptive band. It is not a percentile interval, normal range or clinical reference range.
- Fewer women were studied at older ages (for example 227 at age 45, 41 at age 48 and 10 at age 50), so reference values at older ages may be less statistically stable.
- AMH assays differ between laboratories, so the same blood sample can give slightly different numbers.
What is AMH?
Anti-Müllerian Hormone (AMH) is produced by granulosa cells in small, developing ovarian follicles. AMH is used as an indirect marker of ovarian reserve, helping clinicians assess the remaining egg supply. However, it does not directly measure the total number of eggs remaining in the ovaries.
AMH is measured through a blood test and can generally be tested at any point during the menstrual cycle, although some variation may occur.
How does AMH change with age?
Across large groups of women, average AMH levels are highest in the twenties and gradually fall through the thirties and forties, becoming very low around menopause.
This is a population trend. Individual levels vary widely at every age, and not everyone's AMH falls at the same rate.
What can AMH tell you?
According to guidance from ASRM and ESHRE, AMH is a useful marker of ovarian reserve and can help predict whether the ovaries are likely to show a low or high response to stimulation during IVF or egg-freezing treatment.
Fertility specialists may use AMH or Antral Follicle Count (AFC) to assess ovarian response and help plan treatment. Measuring both is not always necessary, and combining them does not necessarily improve prediction accuracy.
Although AMH can help estimate ovarian response, it cannot reliably predict the exact number of eggs that will be retrieved in an individual treatment cycle.
What can't AMH tell you?
AMH alone cannot accurately predict natural conception, egg quality, the chance of a future live birth, the timing of menopause or the exact number of eggs remaining.
Many people with a lower AMH conceive naturally, and a higher AMH does not guarantee fertility.
Why can AMH levels vary?
AMH levels can vary between individuals and may differ depending on the laboratory assay used. Some biological variation can also occur between tests.
Hormonal contraception, particularly combined hormonal contraceptives, may temporarily lower measured AMH levels. Higher AMH levels are often associated with polycystic ovary syndrome (PCOS), although AMH alone cannot diagnose the condition.
Other factors, including ovarian surgery, certain ovarian conditions and treatments such as chemotherapy, may affect AMH levels. Research has also explored associations with smoking and vitamin D, but findings are not sufficiently consistent to predict how these factors will influence an individual's AMH result.
A fertility specialist can help interpret your AMH level in the context of your medical history, medication use and other investigations.
What could your AMH level mean for egg freezing?
AMH is one of several factors used to assess how your ovaries might respond to stimulation. If you're considering egg freezing, you can explore a research-based estimate of the number of eggs that might be retrieved during a cycle.
Try the Egg Retrieval CalculatorAMH cannot be used directly to predict egg quality or the chance of a live birth. To explore how the number and age of frozen eggs relate to success, use our Frozen Egg Success Calculator. Your AMH result is not passed to either tool.
