Quick answer: AMH (anti-Müllerian hormone) shows roughly how many eggs your ovaries have left. It falls naturally with age. A low AMH doesn't mean you can't get pregnant naturally, and a high AMH is common with PCOS. It's most useful for planning: how soon to try, and whether fertility treatment is likely to work.
Typical AMH by age
Labs use different methods, so always compare with the range on your own report. As a rough guide, typical middle values are:
| Age | Typical AMH (ng/mL) |
|---|---|
| 25 | About 3.0 |
| 30 | About 2.5 |
| 35 | About 1.5 |
| 40 | About 1.0 |
| 45 | About 0.5 or lower |
Some labs report in pmol/L. To convert, multiply ng/mL by about 7.1.
Reading your result
- High (above about 4 ng/mL): many eggs. Often seen with PCOS, especially with irregular periods.
- In the usual range for your age: your egg reserve is as expected.
- Low for your age: fewer eggs than average. It's a reason not to delay trying and to see a doctor early, not a reason to panic.
What AMH can't tell you
- It measures egg number, not egg quality. Quality depends mostly on age.
- It doesn't predict whether you'll get pregnant naturally this month.
- It doesn't check your tubes, your womb or your partner's sperm.
Good to know
AMH can be tested on any day of your cycle, and no fasting is needed. Hormonal contraception can lower AMH slightly, so tell us if you're using it. An antral follicle count (AFC) scan gives a second view of your egg reserve.
