What Does Your AMH Blood Test Actually Tell You?
AMH is one of the first tests ordered in a fertility workup — and one of the most misread. Here's what the number actually means.
AMH (anti-Müllerian hormone) is produced by small follicles in the ovaries. The more follicles you have, the higher your AMH. It's the most commonly used marker of ovarian reserve — but it's a quantity marker, not a quality marker, and that distinction matters.
What AMH measures
AMH reflects the size of your remaining follicle pool. A higher number means more follicles in reserve. A lower number means fewer. It does not tell you about egg quality, the likelihood of conception in any given cycle, or how long you have before fertility declines.
What the numbers mean
- Above 1.0 ng/mL: Generally considered normal to high reserve
- 0.5 to 1.0 ng/mL: Low to borderline reserve
- Below 0.5 ng/mL: Diminished ovarian reserve
These numbers must be interpreted in the context of your age. An AMH of 0.8 ng/mL at 38 has different implications than the same number at 28.
When AMH is most useful
AMH is genuinely useful for predicting ovarian response to stimulation in IVF and for counseling around fertility preservation decisions.
What AMH cannot tell you
- Whether you'll conceive naturally
- The quality of your eggs
- Whether IVF will work
The bottom line
AMH is a useful but limited tool. It tells you about quantity, not quality. A low number warrants a conversation with a reproductive endocrinologist — not a conclusion that conception is off the table.
