AMH(AntiMullerian Hormone) is a snapshot of your ovarian reserve, meaning a rough estimate of remaining eggs in your body.
When is it done : Can be done on any day of menstrual cycle
Why is it done : to evaluate fertility potential and plan fertility treatments accordingly
What is AMH : AMH(AntiMullerian Hormone) is a hormone secreted by the small, growing follicles in the ovary.
Knowing the numbers :
All the females are born with specific number of eggs in each ovary at birth which decline eventually with age…AMH being a direct indicator of Egg Quantity instead of Egg Quality decline with age and the normal range is different for different age groups
Though there might be differences in the reference ranges across different laboartories, the following AMH ranges can be broadly considered and interpreted according to the age groups.
|
Age Group |
Typical AMH Range (ng/mL) |
What It Usually Suggests |
|
Under 30 |
2.0 – 6.8 |
Good, robust egg reserve for your age. |
|
30 – 35 |
1.5 – 4.0 |
Healthy reserve; beginning a gradual, expected decline. |
|
35 – 40 |
1.0 – 3.0 |
Reduced reserve; age begins to play a larger factor. |
|
40 – 45 |
0.3 – 1.5 |
Low reserve; highly expected as menopause approaches. |
|
Over 45 |
Below 0.5 |
Very low reserve; approaching natural menopause. |
- What High AMH Means (> 4.0 or 5.0 ng/mL): A high level indicates an abundant egg supply and in case of unusually high numbers are a primary marker for Polycystic Ovary Syndrome (PCOS) or PMOS(Polyendocrine Metabolic Syndrome). PCOS or PMOS is characterised by multiple small follicles which secrete more AMH but the regular follicle development is hindered.
- What Low AMH Means (< 1.0 ng/mL): This points to a diminished ovarian reserve.
