Calculator
Enter the AMH value, choose the unit, add age, and optionally compare against your lab’s reference interval.
Example Data Table
| Case | Age | AMH (ng/mL) | AMH (pmol/L) | General Band | Example Interpretation |
|---|---|---|---|---|---|
| A | 27 | 3.20 | 22.85 | High | Above average range. Review context and symptoms if PCOS is suspected. |
| B | 31 | 1.90 | 13.57 | Average | Average range with a value near expected age-linked benchmark. |
| C | 35 | 1.10 | 7.85 | Average | Lower end of average range. Compare with ultrasound and clinician review. |
| D | 39 | 0.70 | 5.00 | Low | Low range and below age-linked benchmark. Requires broader fertility context. |
| E | 42 | 0.30 | 2.14 | Severely Low | Markedly low range. Interpretation should remain individualized and clinically reviewed. |

Formula Used
1) Unit conversion
AMH (pmol/L) = AMH (ng/mL) × 7.14
AMH (ng/mL) = AMH (pmol/L) ÷ 7.14
2) General interpretation bands used in this calculator
Severely Low: < 0.40 ng/mL
Low: 0.40 to < 1.00 ng/mL
Average: 1.00 to 3.00 ng/mL
High: > 3.00 to 5.00 ng/mL
Very High: > 5.00 ng/mL
3) Age-linked benchmark model
The calculator uses lower-side reference anchors and linearly interpolates between ages 20, 25, 30, 35, 40, and 45.
4) Benchmark ratio
Benchmark Ratio (%) = [AMH in ng/mL ÷ Age Benchmark in ng/mL] × 100
How to Use This Calculator
Step 1
Enter the patient label if you want a named report.
Step 2
Add age, AMH value, and choose the correct unit.
Step 3
Optionally add your lab’s lower and upper reference values.
Step 4
Submit to view interpretation, ratio, graph, and export options.
For follow-up testing, trend comparison is usually cleaner when the same lab and assay are used.
FAQs
1) What does AMH measure?
AMH helps estimate ovarian reserve, which reflects the remaining follicle pool. It is useful context, but it is not a standalone fertility verdict.
2) Does AMH predict pregnancy chances?
No. AMH can help estimate ovarian response and reserve, but pregnancy chances also depend on age, egg quality, sperm factors, uterus, tubes, and overall health.
3) Can AMH be checked on any day?
AMH varies less across the menstrual cycle than several other reproductive hormones, so it is commonly measured without strict cycle-day timing.
4) Why does this calculator compare age too?
AMH naturally trends downward with age. A value that looks acceptable in isolation may still sit below or above an age-linked expectation.
5) Why can a high AMH need caution?
A higher AMH may suggest a stronger follicle pool, but it can also overlap with PCOS patterns or a stronger response to stimulation.
6) Why should I enter my lab range?
Labs may use different assays and reference intervals. Entering the report range gives a more report-specific comparison beside the calculator’s general model.
7) Is low AMH the same as infertility?
No. Low AMH may suggest lower ovarian reserve, but it does not prove infertility and does not exclude natural conception or treatment success.
8) Should this calculator replace a clinician visit?
No. It is best used as a structured interpretation tool for discussion, not as a diagnosis or individualized treatment decision.
