Ovarian reserve testing estimates how many eggs remain in your ovaries using one or more of three tools: an AMH blood test, an FSH blood test, and an antral follicle count (AFC) ultrasound. These tests are part of a standard infertility workup, but none of them can tell you your exact egg count, your egg quality, or whether you will get pregnant.
The Three Main Tests, Explained
Doctors often order more than one of these tests together because each one has blind spots on its own.
AMH (Anti-Müllerian Hormone)
- What it measures: A hormone made by small ovarian follicles, used as a marker of remaining egg supply
- When it’s done: A blood draw, on any day of the menstrual cycle
- Key limitation: Reflects egg quantity only, not egg quality or your odds of pregnancy
FSH (Follicle-Stimulating Hormone)
- What it measures: A pituitary hormone that tends to rise as ovarian reserve declines
- When it’s done: A blood draw, typically early in the menstrual cycle
- Key limitation: Can shift from cycle to cycle and is affected by hormonal birth control
AFC (Antral Follicle Count)
- What it measures: The number of small follicles visible on a transvaginal ultrasound
- When it’s done: An ultrasound, typically early in the cycle
- Key limitation: Results can vary depending on the equipment and the person performing the scan
Extra Caution: When to Talk to a Provider Sooner Rather Than Later
Some situations call for an earlier conversation with a reproductive specialist rather than waiting to pursue ovarian reserve testing on your own timeline:
- Periods that have stopped or become irregular before age 40
- A personal history of chemotherapy, radiation, or ovarian surgery
- A family history of early menopause or primary ovarian insufficiency
- A known genetic condition linked to reduced ovarian reserve, such as Turner syndrome or fragile X premutation
If any of these apply to you, a qualified clinician can help decide which tests to order and how urgently.
What a Low Result Does — and Doesn’t — Mean
A lower AMH, a higher FSH, or a lower AFC suggests fewer remaining eggs than average for your age. It does not mean you are infertile. Many people with low ovarian reserve markers conceive, including without fertility treatment, because reserve is only one piece of the fertility picture. Egg quality, ovulation regularity, uterine health, and a partner’s fertility all factor in separately and are not captured by these tests.
What a Normal Result Does — and Doesn’t — Mean
A result in the expected range for your age is reassuring about egg supply, but it is not a pregnancy guarantee. These tests do not check egg quality, tubal patency, or whether ovulation is happening regularly. Someone with normal ovarian reserve markers can still have unexplained infertility or another underlying issue that these three tests were never designed to catch.
Why Age-Adjusted Reference Ranges Matter
AMH and AFC naturally decline with age, and FSH naturally rises. Reference ranges also vary between labs and between the specific assay used, which is why a result should always be interpreted against the range your own lab reports rather than a number found online. Ask your provider to explain where your result falls relative to your age group, using their lab’s specific reference range.
A Simple Worksheet: Questions to Bring to Your Appointment
- What test result did I get, and what is the reference range for my age at this specific lab?
- Does this result change your recommendation for how soon to seek fertility care?
- Which other tests, if any, would give a fuller picture, such as a partner’s semen analysis, ovulation tracking, or a tubal evaluation?
- Should this test be repeated, and if so, when?
- What lifestyle or timeline factors should I be thinking about based on this result?
Evidence Limits
Ovarian reserve tests are most useful for predicting how someone might respond to ovarian stimulation during IVF. They are far less reliable for predicting natural conception or the exact timing of menopause in an individual. Research in this area continues to evolve, and the current guidance is to use these results as one input among several, not as a standalone verdict on fertility.
Frequently Asked Questions
Can I test my ovarian reserve at home?
At-home AMH kits exist, but results still need a qualified clinician to interpret correctly alongside your age, cycle history, and other findings. A home test alone shouldn’t guide major decisions.
Does a low AMH mean I’m infertile?
No. Low AMH points to a smaller egg supply, but it doesn’t measure egg quality or your ability to conceive. Many people with low AMH still get pregnant.
Can these tests predict exactly when I’ll reach menopause?
Not precisely. AMH trends can offer a general sense of ovarian aging, but these tests are not a reliable calendar for pinpointing your menopause age.
How often should ovarian reserve testing be repeated?
That depends on your age, your fertility goals, and your provider’s assessment. There’s no single interval that fits everyone, so this is a question to bring to your own clinician.
