AMH Test Explained: What Your Result Actually Means for Fertility
AMH (Anti-Müllerian Hormone) is the most important fertility marker most women never test. Here is what your result means, what the numbers mean by age, and how to get tested privately in Australia.
Get Your AMH Test — $139AMH is a blood test that estimates your ovarian reserve — how many eggs you have remaining. Levels naturally decline with age. A typical healthy AMH for women in their 20s is 2.0 to 6.8 ng/mL, dropping steadily with age. You can test AMH on any day of your cycle and you do not need a GP referral to order one privately in Australia.
- AMH measures egg quantity (ovarian reserve) — not egg quality, not current fertility
- AMH can be tested on any day of your cycle, unlike FSH, LH or oestradiol
- Low AMH does not mean you cannot conceive naturally — it is information, not a verdict
- The contraceptive pill can modestly lower AMH readings — test 6+ weeks after stopping for a true read
- PCOS often produces high AMH due to many small follicles, even if ovulation is irregular
- You can get a private AMH test in Australia without a GP referral
What is AMH?
Anti-Müllerian Hormone is produced by the small developing follicles in your ovaries. Each follicle is a tiny sac containing an immature egg. Because AMH comes directly from these follicles, your blood AMH level gives an indirect count of how many follicles you have left. The more follicles, the higher your AMH.
This is why AMH is called the "ovarian reserve" hormone — it is the best widely available blood marker for estimating egg quantity.
What AMH does not measure:
- Egg quality. AMH tells you how many follicles you have, not how healthy those eggs are. Egg quality is more strongly tied to age than to AMH.
- Current fertility. A woman with low AMH can still conceive naturally.
- Time to menopause precisely. AMH is associated with menopause timing but cannot predict exact dates.
AMH is one piece of the fertility picture, not the whole answer. But it is a piece most women never see until they are already struggling.
AMH levels by age: what is normal
AMH naturally declines as you age. The table below shows general reference ranges in ng/mL — the standard Australian unit. Your individual context always matters more than the raw number.
| Age range | Average AMH (ng/mL) | What it typically indicates |
|---|---|---|
| Under 25 | 2.0 to 6.8 | Strong ovarian reserve |
| 25 to 30 | 1.5 to 4.0 | Healthy range |
| 30 to 35 | 1.0 to 3.5 | Beginning to decline, still normal |
| 35 to 40 | 0.5 to 2.5 | Notable decline, fertility planning more urgent |
| 40 to 45 | 0.2 to 1.0 | Significant reduction |
| Over 45 | Under 0.5 | Approaching menopause |
Some labs report AMH in pmol/L. To convert, multiply ng/mL by 7.14 (so 1.0 ng/mL = 7.14 pmol/L).
A few important caveats: AMH fluctuates less than other hormones across your cycle — you can test on any day. Hormonal contraception can lower AMH modestly, and PCOS often pushes AMH significantly higher than average due to the high number of small follicles present.
Test AMH privately — no GP referral needed
Get AMH TestWhy women get AMH tested
Family planning timing
The most common reason. Women in their late 20s through mid-30s want a numerical answer to the question: how much time do I have? AMH is one of the few markers that gives you that answer directly.
Investigating cycle changes
Irregular periods, shorter cycles, or early signs of menopause. Low AMH alongside elevated FSH is the classic biochemical signature of diminished ovarian reserve.
PCOS investigation
High AMH is one of the diagnostic clues for Polycystic Ovary Syndrome (also referred to as Polycystic Metabolic Syndrome). Combined with elevated testosterone and irregular cycles, AMH helps confirm the pattern. The PCOS Hormone Check covers this alongside the metabolic markers typically affected.
IVF preparation
AMH predicts how well your ovaries will respond to stimulation drugs. Higher AMH generally means more eggs retrieved per cycle, which influences treatment protocols and success expectations.
Egg freezing decisions
Women considering egg freezing use AMH to time the decision and estimate how many cycles may be needed to bank a sufficient number of eggs.
When should you test AMH?
The honest answer: earlier than most women think.
Research shows that women lose about 90% of their maximum potential egg supply by age 30 — but that figure needs context. Women begin life with 1 to 2 million eggs at birth, so even at 30, a significant number remain and natural conception is absolutely achievable. The decline continues through the 30s, accelerating after 35. The point is not to cause alarm, but to note that most women only discover their AMH numbers when they have been trying to conceive without success for over a year, at which point some earlier options are no longer available.
AMH can be tested on any day of your cycle with no scheduling complexity. If you are thinking about your fertility timeline, it is a reasonable marker to know.
What to do if your AMH is low
A low AMH result can feel devastating. It should not.
Low AMH does not equal infertility. Plenty of women with low AMH conceive naturally. AMH measures egg quantity, not quality, and not your ability to ovulate. Egg quality is more closely linked to age — a 30-year-old with low AMH still has younger, healthier eggs than a 40-year-old with high AMH.
Use the result as information. It informs timing decisions, egg freezing conversations and fertility consultations. It is not a verdict.
The natural next step is to get the rest of the picture. Pair AMH with FSH, LH, oestradiol and progesterone for the full ovarian reserve story. The Female Fertility Panel includes all of these in one draw.
What does a high AMH mean?
A high AMH result on its own does not mean something is wrong. In many women it simply reflects excellent ovarian reserve for their age, which is a positive finding. However, AMH that is significantly above the expected range for your age can sometimes be associated with PCOS, because polycystic ovaries contain a high number of small follicles that each produce AMH.
Importantly, a high AMH does not diagnose PCOS on its own. PCOS is a clinical diagnosis that involves a combination of factors including cycle regularity, androgen levels and ultrasound findings. If your AMH is elevated and you have irregular periods, acne, hair changes or other symptoms, the PCOS Hormone Check covers testosterone, SHBG, insulin and glucose alongside the relevant hormones.

Frequently asked questions
Privately, AMH testing costs $139 privately. Medicare covers AMH only in limited circumstances through a GP referral. Through MediTests, the AMH test ($139) is available privately without a referral.
AMH requires a blood draw at an accredited pathology collection centre. It cannot be reliably tested at home with current technology. With 3,300+ collection centres across Australia, a walk-in appointment is straightforward.
Hormonal contraception can lower AMH modestly. The effect is reversible after stopping. If you have been on the pill long-term, your reading may slightly under-represent your true reserve. For the most accurate result, test 6 weeks or more after stopping.
A single test provides a useful snapshot. If you are making a significant decision (such as egg freezing or fertility treatment), having a follow-up test at a later point gives you a trajectory that is more informative than a single reading. Discuss timing with your GP or fertility specialist based on your individual situation.
As a guide: 2.0 to 6.8 ng/mL for women under 25, dropping to 1.0 to 3.5 ng/mL in the early 30s, and 0.5 to 2.5 ng/mL in the late 30s. See the age table in this article for full detail. Reference ranges vary slightly between labs.
No. Follicles do not regenerate. AMH reflects how many remain. However, optimising Vitamin D status, stopping smoking, managing weight and reducing oxidative stress can support egg quality, which matters alongside quantity.
Low AMH is associated with earlier menopause but is not a precise predictor. Many women with lower-than-average AMH for their age still reach menopause at average ages. One low reading is not a timeline.
For a complete fertility picture, AMH pairs best with FSH, LH, oestradiol, progesterone and prolactin. The Female Fertility Panel includes all of these. If PCOS is suspected, the PCOS Hormone Check adds testosterone, insulin and glucose to complete the metabolic picture.
