As a general guideline, the following amounts (in nanograms per milliliter) reflect the lower limit of serum AMH values by age:
45 years old: 0.5 ng/mL
40 years old: 1 ng/mL
35 years old: 1.5 ng/ mL
30 years old: 2.5 ng/mL
25 years old: 3.0 ng/mL
High (often PCOS): Over 4.0 ng/ml
Normal: 1.5 – 4.0 ng/ml
Low Normal Range: 1.0 – 1.5 ng/ml
Low: 0.5 – 1.0 ng/ml
Very Low Less than 0.5 ng/ml
If you test your AMH today and find it low, it doesn’t imply you can’t get pregnant tomorrow or in three months. AMH levels below 1.6 ng/mL indicate fewer eggs retrieved with IVF. Levels less than 0.4 ng/mL are considered extremely low.
While test findings are useful, it’s also worth noting that you have fewer eggs as you age. This is very normal! It means that AMH levels decline during a woman’s reproductive life.
Just because you have “normal” AMH levels now does not mean they will remain normal in the future. All women will experience a decline in fertility as they age, but the rate at which this decline happens varies from woman to woman and cannot be anticipated.
The amounts shown above are considered conservative estimates, and the cutoffs vary based on the lab. Any test results should be discussed with the doctor who ordered the test.
