Understand your AMH fertility test results. What's normal, what's low, and what AMH means for your IVF treatment options and success.
Understanding Your AMH Results: What Your Fertility Test Means
AMH (Anti-Müllerian Hormone) is one of the most important fertility tests. But getting your results can be confusing—or frightening if numbers seem "low." Here's what AMH actually means.
Key Takeaways
- What AMH measures: Your ovarian reserve (quantity of eggs remaining), not egg quality
- Normal range: 15-35 pmol/L (or 2.0-5.0 ng/mL)—though values decline naturally with age
- Low AMH is not hopeless: It means fewer eggs, not inability to conceive; quality matters as much as quantity
- Age determines quality: A 28-year-old with low AMH has better quality eggs than a 42-year-old with normal AMH
- IVF response: AMH helps predict how many eggs you'll retrieve, allowing doctors to customize your protocol
What Is AMH?
AMH is a hormone produced by cells in your ovarian follicles. It reflects your ovarian reserve—how many eggs you have remaining.
| What AMH Measures | What AMH Doesn't Measure |
|---|---|
| Quantity of eggs | Quality of eggs |
| Ovarian reserve | Ability to get pregnant naturally |
| Expected IVF response | Whether you'll have a baby |
AMH Levels by Age
Reference Ranges (pmol/L and ng/mL)
| Category | pmol/L | ng/mL |
|---|---|---|
| High | >35 | >5.0 |
| Normal | 15-35 | 2.0-5.0 |
| Low-normal | 7-15 | 1.0-2.0 |
| Low | 3-7 | 0.4-1.0 |
| Very low | <3 | <0.4 |
Expected AMH by Age
| Age | Typical AMH (pmol/L) |
|---|---|
| 25 | 25-35 |
| 30 | 20-28 |
| 35 | 12-22 |
| 38 | 8-16 |
| 40 | 5-12 |
| 42 | 3-8 |
| 44+ | <5 |
Note: Wide individual variation exists. These are averages.
What Your AMH Means for IVF
High AMH (>35 pmol/L)
| Implication | Details |
|---|---|
| Good egg numbers expected | 15+ eggs per retrieval |
| OHSS risk | Higher—may need careful monitoring |
| Prognosis | Excellent response to stimulation |
Normal AMH (15-35 pmol/L)
| Implication | Details |
|---|---|
| Good response expected | 8-15 eggs per retrieval |
| Standard protocols work well | Typical stimulation |
| Prognosis | Good for IVF |
Low-Normal AMH (7-15 pmol/L)
| Implication | Details |
|---|---|
| Moderate response expected | 5-10 eggs per retrieval |
| May need higher doses | Adjusted protocol |
| Prognosis | Still reasonable—quality matters |
Low AMH (3-7 pmol/L)
| Implication | Details |
|---|---|
| Lower egg numbers expected | 3-6 eggs per retrieval |
| Higher medication doses | More aggressive stimulation |
| Multiple cycles may be needed | To accumulate embryos |
| Prognosis | Challenging but not impossible |
Very Low AMH (<3 pmol/L)
| Implication | Details |
|---|---|
| Few eggs expected | 1-4 eggs per retrieval |
| Consider egg donation | May be recommended |
| Don't delay treatment | Every month counts |
| Prognosis | Difficult but pregnancies occur |
AMH Myths vs. Reality
Myth: Low AMH means I can't get pregnant
Reality: Low AMH means fewer eggs, not no eggs. Women with low AMH get pregnant—sometimes naturally, often with IVF. Quality matters as much as quantity.
Myth: High AMH guarantees success
Reality: High AMH means more eggs, but egg quality (mainly determined by age) affects success. High AMH with poor quality still struggles.
Myth: AMH predicts natural fertility
Reality: AMH primarily predicts IVF response. Women with low AMH often conceive naturally. High AMH doesn't mean easy natural conception.
Myth: AMH is the only important test
Reality: AMH is one piece. Antral follicle count, FSH, age, and partner factors all matter.

Complete Picture
| Test | What It Shows |
|---|---|
| AMH | Ovarian reserve (quantity) |
| Antral Follicle Count (AFC) | Visible follicles (confirms AMH) |
| FSH | Pituitary response (Day 3) |
| Estradiol | Baseline estrogen (Day 3) |
| Age | Proxy for egg quality |
Ideal Testing Panel
| Test | When |
|---|---|
| AMH | Any time in cycle |
| FSH + Estradiol | Day 2-4 of cycle |
| AFC ultrasound | Day 2-4 of cycle |
What to Do with Your Results
If AMH Is Normal/High
- Proceed with confidence
- Standard protocols likely work
- Don't delay unnecessarily (quality still declines with age)
If AMH Is Low
- Don't panic—low AMH doesn't mean failure
- Consult a specialist—get personalized advice
- Consider acting sooner—delays reduce options
- Discuss protocol options—tailored approaches help
- Consider egg freezing—if not ready for baby now
If AMH Is Very Low
- Get expert consultation—specialized clinics help
- Discuss egg donation—as backup or primary option
- Act quickly—time is not on your side
- Consider multiple retrievals—accumulate embryos
- Manage expectations—but don't lose hope
Questions to Ask Your Doctor
- What does my AMH mean for my specific situation?
- How many eggs can we expect per retrieval?
- What protocol do you recommend for my AMH level?
- Should I consider egg freezing now?
- At what point would you recommend egg donation?
- How does my age factor in with my AMH?
Frequently Asked Questions
Can AMH levels change?
Slightly, month to month. They trend downward with age but don't dramatically improve. Supplements claiming to "boost AMH" don't truly increase ovarian reserve.
Should I retest if my AMH was low?
Maybe—if there's doubt about the test accuracy. But don't keep retesting hoping for different results.
Does AMH affect egg quality?
No. AMH measures quantity. Quality is primarily age-related. A 28-year-old with low AMH has better quality eggs than a 42-year-old with normal AMH.
What if my AMH and AFC don't match?
Both should be considered. If they conflict significantly, your doctor will weigh the evidence.
Is there anything I can do to improve my reserve?
Nothing proven significantly increases ovarian reserve. Focus on overall health, stop smoking, and avoid delaying treatment.
The Bottom Line
AMH is one important number, not your fertility destiny. Low AMH is challenging but not hopeless. High AMH is encouraging but not a guarantee.
What matters most: getting good medical advice and making informed decisions.
