AMH Levels Explained: Normal Ranges, Chart by Age & Fertility Meaning (2026)

What Is AMH and Why Does It Matter?

AMH (Anti-Müllerian Hormone) is a protein produced by the small follicles in your ovaries — the ones that contain your immature eggs. The more follicles you have, the higher your AMH. This makes AMH the most reliable single blood test for measuring ovarian reserve (how many eggs remain). Unlike FSH, AMH can be tested on any day of your cycle, making it the most convenient fertility hormone to test.

What Is a Normal AMH Level?

There's no single 'normal' — it depends entirely on your age. Here are the general categories used by most fertility clinics:

• High AMH (>4.0 ng/mL / >28.6 pmol/L): May indicate PCOS or unusually high reserve. Good for IVF egg retrieval but may increase OHSS risk.
• Normal AMH (1.0–4.0 ng/mL / 7.1–28.6 pmol/L): Healthy ovarian reserve. Good prognosis for natural conception and IVF.
• Low-Normal AMH (0.7–1.0 ng/mL / 5.0–7.1 pmol/L): Below average but not critically low. Time-sensitive planning recommended.
• Low AMH (0.3–0.7 ng/mL / 2.1–5.0 pmol/L): Diminished reserve. Specialist consultation recommended.
• Very Low AMH (<0.3 ng/mL / <2.1 pmol/L): Severely diminished reserve. Urgent specialist consultation advised.

AMH Levels by Age Chart (ng/mL and pmol/L)

AMH naturally declines as you age. For a detailed age-by-age breakdown, see our AMH Levels by Age Chart. Here are the population averages:

• Under 25: 3.0–4.0 ng/mL (21–29 pmol/L) average, range 1.5–6.0
• 25–30: 2.5–3.5 ng/mL (18–25 pmol/L) average
• 30–35: 1.5–3.0 ng/mL (11–21 pmol/L) — decline begins accelerating
• 35–38: 1.0–2.5 ng/mL (7–18 pmol/L) — significant acceleration after 37
• 38–40: 0.7–1.5 ng/mL (5–11 pmol/L)
• 40–43: 0.3–1.0 ng/mL (2–7 pmol/L)
• Over 43: Below 0.5 ng/mL (3.6 pmol/L) average

AMH ng/mL vs pmol/L: Quick Conversion

US/Australia report in ng/mL; UK/Europe report in pmol/L. The conversion factor is 7.14. For a complete conversion chart with all common values, see our dedicated guide.

• ng/mL → pmol/L: Multiply by 7.14
• pmol/L → ng/mL: Divide by 7.14
• Quick reference: 1.0 ng/mL = 7.1 pmol/L | 2.0 = 14.3 | 3.0 = 21.4 | 5.0 = 35.7

What Does Low AMH Mean for Getting Pregnant?

This is the question that causes the most anxiety — and the answer may surprise you. Research (Steiner et al., 2017, JAMA) shows that women under 40 with low AMH have similar monthly natural conception rates to women with normal AMH. Your body only needs ONE egg per month, and AMH doesn't measure egg quality. Low AMH primarily affects IVF response (fewer eggs retrieved), not your ability to conceive naturally. Read our complete guide: Can You Still Get Pregnant with Low AMH?

What Does High AMH Mean?

AMH above 4.0–5.0 ng/mL is considered elevated and often associated with PCOS (Polycystic Ovary Syndrome). In PCOS, the ovaries contain too many small follicles, inflating the AMH number. While this means more eggs, PCOS can cause irregular ovulation, making conception harder. The good news: PCOS is very treatable. See our complete guide: High AMH and PCOS

What Is a Good AMH Level for IVF?

For IVF, AMH predicts how many eggs you'll retrieve during stimulation. Higher AMH = more eggs = more embryos to choose from = higher cumulative success rates. But there's no 'minimum' AMH for IVF — women with AMH 0.3 still have successful cycles. See our detailed guides: What AMH Level Do You Need to Get Pregnant? and AMH Levels & IVF: How Many Eggs Will I Get?

• AMH >3.5: Expect 15-25+ eggs — excellent IVF prognosis, but OHSS risk needs monitoring
• AMH 1.5–3.5: Expect 8-18 eggs — standard protocols work well
• AMH 0.5–1.5: Expect 3-8 eggs — may need higher doses or specialized protocols
• AMH <0.5: Expect 1-4 eggs — mini-IVF or natural cycle IVF may be recommended

Factors That Can Affect Your AMH Result

While AMH is more stable than FSH or estradiol, several factors can influence your reading. For a complete guide on testing, see When to Test AMH.

• Hormonal birth control: Can suppress AMH by 20-30%. Wait 2-3 months after stopping for accurate baseline.
• Vitamin D deficiency: May lower AMH readings — correcting deficiency can modestly improve AMH. See Can AMH Levels Improve?
• Smoking: Accelerates ovarian aging and lowers AMH at any age
• Recent ovarian surgery: Cystectomy can reduce AMH if ovarian tissue was removed
• BMI extremes: Both very low and very high BMI may affect AMH readings

AMH vs Other Fertility Tests: Which Do You Need?

AMH is important but it's just one piece. For the complete picture, your doctor will also check FSH (day 3), AFC (antral follicle count via ultrasound), and possibly estradiol. Read our comparison guide: AMH vs FSH vs AFC: Which Test Do You Actually Need?

• AMH: Test any day. Best for ovarian reserve screening. Stable throughout cycle.
• FSH: Must test day 2-4. High FSH = brain working harder to stimulate fewer follicles.
• AFC: Ultrasound count of small follicles. Most direct real-time measure.
• Low AMH + High FSH + Low AFC = strongest evidence of diminished reserve

What to Do After Getting Your AMH Results

Don't panic, don't Google for hours, and don't make any decisions in isolation. Here's your action plan:

• Step 1: Run the AMH Analyzer — see your exact age-adjusted percentile in 60 seconds
• Step 2: Look up your specific AMH number for a detailed interpretation
• Step 3: If concerned, book a consultation with a reproductive endocrinologist (not just OB/GYN)
• Step 4: Complete the picture — get AFC and FSH tested alongside AMH
• Step 5: Make a plan — whether that's monitoring, lifestyle optimization, egg freezing, or treatment

Key takeaways

• AMH measures egg QUANTITY (ovarian reserve), not egg QUALITY — quality depends on age
• Normal AMH ranges from 1.0-4.0 ng/mL (7-29 pmol/L), but always compare to YOUR age group
• Low AMH does NOT mean you can't get pregnant — natural conception rates are similar under 40
• High AMH (>4-5 ng/mL) may indicate PCOS, which is highly treatable
• Convert units: ng/mL × 7.14 = pmol/L | pmol/L ÷ 7.14 = ng/mL
• Use the free AMH Analyzer for your exact age-adjusted percentile and personalized doctor questions
