Why does the cycle day matter?

FSH and estradiol both change substantially across the cycle, and are only interpretable in the first few days. AMH is different — it is stable enough to draw any day. Because two of the three need early-cycle timing, we ask you to book for days 2 to 4.

What if my periods are irregular or absent?

Come whenever is practical and note that your cycles are irregular. AMH remains informative. FSH and estradiol are harder to interpret without a known cycle day, so your clinician may want to repeat them or interpret them alongside the rest of your history.

Does hormonal birth control affect the results?

Yes. Combined hormonal contraception can lower AMH and suppress FSH and estradiol, so results taken while using it may understate your reserve. Tell us if you are using it, and discuss with your clinician whether to test after a break.

What does a low AMH mean?

It suggests a smaller remaining follicle pool than is typical for your age. It is not a diagnosis of infertility and it does not mean you cannot conceive — many people with low AMH do. It is information for planning, and a reason to discuss timing with a clinician rather than a verdict.

Ovarian Reserve Blood Test Panel

Ovarian reserve describes roughly how many eggs remain, not how likely you are to conceive. These three markers are the standard way to assess it, and they are most informative read together.

Ovarian reserve refers to the size of the remaining egg pool. It declines with age in everyone, at a pace that varies considerably from person to person, and these three markers are the standard way to assess it.

AMH (anti-Müllerian hormone) is produced by small developing follicles and reflects the size of that pool. It is relatively stable across the menstrual cycle, so it can be drawn on any day.

FSH is the pituitary signal telling the ovaries to recruit a follicle. As reserve falls, the pituitary compensates by pushing harder, so a rising early-cycle FSH suggests the ovaries are becoming less responsive.

Estradiol is measured alongside FSH because it provides the context. An early rise in estradiol can suppress FSH into the normal range and mask a reduced reserve, so an FSH result is difficult to interpret without it.

What these tests can tell you is how your reserve compares with others your age, which is genuinely useful when planning — considering egg freezing, deciding on timing, or preparing for fertility treatment, where these values help predict response to ovarian stimulation.

What they cannot tell you is whether or when you will conceive naturally. In people who are not otherwise experiencing infertility, a single AMH measurement does not reliably predict time to pregnancy. A low result is not a diagnosis of infertility, and a reassuring one is not a guarantee.

What This Panel Measures

Three markers of ovarian reserve: AMH (reflecting the remaining follicle pool), FSH (the pituitary signal to the ovaries) and estradiol (which provides the context needed to interpret FSH correctly).

Who Should Get This Panel

People planning pregnancy later, considering egg freezing, preparing for fertility treatment, wanting a baseline before or after treatments that affect the ovaries, or investigating irregular cycles alongside other testing.

When to Get Tested

Cycle days 2-4 if you are having regular periods. AMH is stable across the cycle, but FSH and estradiol are not, and a mid-cycle draw makes both uninterpretable.

Understanding Your Results

Results are reported with age-referenced ranges, since what counts as expected changes considerably by age. AMH is usually the headline number, read alongside a day 2-4 FSH and estradiol. Higher FSH with low estradiol suggests reduced reserve; a raised estradiol means the FSH should be interpreted cautiously. These numbers describe reserve, not fertility, and are best discussed with a clinician in the context of your plans.
