Normal AMH Levels by Age Chart (Ages 20–45)

AMH declines steadily with age. Values below are an age-based population model (10th, 50th and 90th percentiles) built from large published nomograms. Laboratories and assays differ — always compare with your lab’s own reference range.

Age	10th pct (ng/mL)	Median (ng/mL)	90th pct (ng/mL)	Range in pmol/L
20	1.76	4.20	10.04	12.5 – 71.7
25	1.51	3.60	8.61	10.8 – 61.4
28	1.35	3.23	7.71	9.6 – 55.1
30	1.25	3.00	7.17	9.0 – 51.2
32	1.09	2.60	6.22	7.8 – 44.4
34	0.91	2.18	5.22	6.5 – 37.3
35	0.84	2.00	4.78	6.0 – 34.1
36	0.75	1.79	4.28	5.3 – 30.5
37	0.67	1.60	3.82	4.8 – 27.3
38	0.59	1.41	3.38	4.2 – 24.1
40	0.46	1.10	2.63	3.3 – 18.8
42	0.33	0.80	1.91	2.4 – 13.7
44	0.21	0.50	1.20	1.5 – 8.6
45	0.17	0.40	0.96	1.2 – 6.8

Unit conversion: 1 ng/mL = 7.14 pmol/L • 1 pmol/L = 0.14 ng/mL. AMH can be tested on any day of the cycle and is lower in women using hormonal contraception.

Low AMH (DOR) vs. High AMH (PCOS): What It Means

AMH (ng/mL)	Interpretation	What to discuss with your doctor
< 0.5	Very low reserve	Prompt specialist review; IVF may yield few eggs; consider earlier treatment or donor-egg options if needed
0.5 – 1.0	Low (diminished ovarian reserve)	Don’t delay trying; check FSH, AFC; consider egg freezing if not ready
1.0 – 3.5	Normal	Standard approach
3.5 – 5.0	High-normal	Good IVF response expected
> 5.0	High — often PCOS	Assess cycles & androgens (Rotterdam criteria); OHSS-safe IVF protocol

AMH ≠ fertility. In a JAMA 2017 study, women with low AMH were just as likely to conceive naturally within 12 months as women with normal AMH.
AMH is best for predicting response to IVF stimulation and planning egg freezing.
Vitamin D deficiency, smoking and ovarian surgery can lower AMH.

Frequently Asked Questions

What is a normal AMH level by age?

Roughly 3.0 ng/mL at 30, 2.0 ng/mL at 35, 1.1 ng/mL at 40 and 0.4 ng/mL at 45 (medians). A wide range is normal at every age — see the age chart above.

Can I get pregnant with low AMH?

Yes. AMH reflects the number of eggs remaining, not their quality or your monthly chance of natural conception. Many women with low AMH conceive naturally, but they should not delay seeing a specialist.

How do I convert AMH from pmol/L to ng/mL?

Divide pmol/L by 7.14 to get ng/mL, or multiply ng/mL by 7.14 to get pmol/L. For example, 14.3 pmol/L = 2.0 ng/mL.

Is a high AMH good?

A high AMH usually means a good egg supply, but values above about 5 ng/mL are often seen with PCOS and increase the risk of ovarian hyperstimulation during IVF.

Can AMH levels be increased?

No treatment reliably increases the number of eggs. Correcting vitamin D deficiency and stopping smoking may modestly help results. Focus on timely evaluation and treatment.
