Low AMH: Can You Still Get Pregnant?

A low AMH result can feel like a door closing, especially when it comes from an at-home kit with little explanation. The evidence is more reassuring than the number suggests. Low AMH tells you something about how many eggs are left; it says much less about whether you will get pregnant. This guide covers what the research shows, how low AMH changes fertility treatment, and when it should change your timeline.

What does low AMH mean?

AMH (anti-Müllerian hormone) is made by small follicles in the ovary and is the most sensitive blood marker of ovarian reserve, the number of eggs remaining.² A low AMH means fewer eggs remain than is typical for your age. It does not measure egg quality: ASRM says ovarian reserve tests measure only quantity, and that diminished ovarian reserve does not necessarily mean an inability to conceive.²

There is no universal cut-off. Studies cited by ASRM have defined low AMH as below 0.7 ng/mL or below 1 ng/mL.² For the basics of the test, see AMH explained.

Can you get pregnant with low AMH?

Yes. The strongest evidence is the Time to Conceive study, published in JAMA in 2017. Researchers followed 750 women aged 30 to 44 with no history of infertility who had been trying for three months or less.¹

Predicted cumulative probabilities from the study; the differences were not statistically significant.¹ The authors concluded that biomarkers of diminished ovarian reserve were not associated with reduced fertility in this group.¹

ASRM’s 2020 committee opinion reaches the same conclusion across studies: ovarian reserve markers do not predict current reproductive potential in women with unproven fertility, and should not be used as a fertility test for people who are not infertile.² Another trial ASRM cites, in 1,202 women aged 18 to 40 with prior pregnancy loss, found similar cumulative pregnancy rates with AMH below 1 ng/mL and with normal AMH.²

Why does it work this way? Natural conception needs one egg per cycle. Having fewer eggs in reserve does not, by itself, stop you releasing one each month while you still ovulate.

Low AMH and age

Age is the bigger story. ACOG and ASRM say fertility declines gradually from about age 32 and more rapidly after 37.⁴ ASRM says female age is the single most important predictor of fertility, and that age is a much stronger predictor of reproductive success than ovarian reserve.³² In a North American cohort of 2,962 couples, women aged 37 to 39 had about 60% of the per-cycle chance of conceiving of women aged 21 to 24, and women 40 to 45 about 40%.⁶

So a low AMH at 30 is mostly a reason to keep the usual timeline and not panic. A low AMH at 38 is a reason to act on the timeline you already have: get evaluated after 6 months of trying, or now if you are over 40.⁴ See getting pregnant after 35.

Low AMH and IVF

AMH matters most once you are considering IVF. ASRM says AMH and antral follicle count reliably predict how many eggs stimulation will produce and whether you are likely to respond poorly or excessively to the drugs.² Low AMH usually means fewer eggs per retrieval.

That is not a reason to be turned away. In national data on more than 5,000 fresh IVF cycles in women with extremely low AMH (below 0.16 ng/mL), 54% of cycles were canceled and 25% had no embryo to transfer, but the live birth rate was 9.5% per cycle started.² ASRM says extremely low AMH can be used to counsel patients about a lower egg yield, but not to refuse treatment.² AMH and antral follicle count also have only a weak association with pregnancy and live birth after IVF.² For ovarian stimulation with IUI, a secondary analysis of a trial of 900 women with unexplained infertility found AMH did not predict pregnancy rates, so a low result is not a reason to skip IUI if it is otherwise the right next step.²

What can lower an AMH result?

• Hormonal contraception. ASRM says AMH may be decreased in people using hormonal contraceptives and should be interpreted with caution.²
• Ovarian surgery. The ESHRE endometriosis guideline says surgery for ovarian endometriomas is likely to have a negative impact on ovarian reserve.⁵
• Cancer treatment. ASRM lists chemotherapy and radiation among conditions that predispose to diminished ovarian reserve, and recommends evaluation without delay.³

Should you freeze your eggs if your AMH is low?

Not because of AMH alone. ASRM says ovarian reserve markers should not be used to promote planned egg freezing, and that the decision should be based on your reproductive plans and age.² If you are considering it, see egg freezing cost and talk to a reproductive endocrinologist about what your age and AMH together mean for expected egg numbers.

Questions to ask your clinician

• What does my AMH mean for my age, and should we confirm it with an antral follicle count?
• Was I on hormonal contraception when tested, and does that change how you read it?²
• Given my age and how long we have tried, how long should we keep trying before treatment?
• If we move to IVF, how many eggs would you expect per retrieval, and how many cycles should we plan for?
• Has my partner had a semen analysis yet?³

What to do next

1. Don’t stop trying. A low result is not a reason to give up natural attempts.¹
2. Know your threshold. Get evaluated after 12 months under 35, 6 months at 35 or older, or now if you are over 40 or have irregular periods.³⁴ See when to see a fertility specialist.
3. Test the other partner. A semen analysis belongs at the start of any evaluation when a male partner is involved.³ See semen analysis results.
4. Recheck if needed. If you were on hormonal contraception when tested, ask whether a repeat test makes sense.²
