A low AMH result or a cycle that produced only a few eggs changes how you should plan IVF abroad. The test does not tell you whether you can get pregnant. It tells you roughly how many eggs a clinic can expect to collect per cycle, and that number drives everything else: how many trips you may need, how a package should be priced, and when donor eggs become a reasonable conversation.
This guide explains what AMH and antral follicle counts actually measure, how specialists define "poor response," which protocol changes and add-on drugs have evidence behind them, and how to compare clinics when your egg numbers are low. If you are also over 40, read it alongside our guide to IVF abroad over 40, which covers age limits and age-specific success data.
What AMH and antral follicle count really tell you
Anti-Müllerian hormone (AMH) is made by small follicles in the ovary. Because it is fairly stable across the menstrual cycle, it can be drawn on almost any day. The antral follicle count (AFC) is an ultrasound count of the small 2–10 mm follicles in both ovaries, done early in the cycle.1
Both tests predict how many eggs you are likely to produce with stimulation. Neither is a good predictor of pregnancy. The American Society for Reproductive Medicine (ASRM) says AMH on its own is only weakly predictive of pregnancy, and that ovarian reserve markers are poor predictors of natural fertility. In one cohort it cites, women with low AMH had cumulative pregnancy rates after 6 and 12 months of trying that were similar to women with normal levels.1
ESHRE, the European society for reproduction and embryology, recommends AFC or AMH over other ovarian reserve tests for predicting response, and advises against relying on basal FSH, inhibin B, basal estradiol, age or BMI for that purpose.2
Labs report AMH in either ng/mL or pmol/L, and assays differ. When you send results abroad, include the unit, the lab name and the date. ASRM also notes that AMH can be lower in people using hormonal contraception, so mention it if you were on the pill when tested.1
The most important practical point: ASRM states that very low AMH values should not be used to refuse treatment, and that ovarian reserve tests should not be the only reason to deny access to IVF.1 If a clinic turns you away on AMH alone, or tells you donor eggs are your only option based on a single number, get another opinion.
Bologna and POSEIDON: how "poor responder" is defined
Two classification systems come up in clinic consultations and research papers. Knowing which one a clinic uses helps you read its success claims.
The Bologna criteria (ESHRE, 2011)
An ESHRE working group defined poor ovarian response as meeting at least two of three features: age 40 or older (or another risk factor), a previous poor response of three or fewer eggs with a conventional protocol, and an abnormal ovarian reserve test. Two previous poor responses after maximal stimulation are enough on their own.31 ESHRE's stimulation guideline uses the same definition, describing low response as three or fewer follicles on trigger day and/or three or fewer eggs collected.2
The POSEIDON groups (2016)
The POSEIDON group argued that Bologna lumps together very different patients. It proposed four "low prognosis" groups based on age (under or over 35) and whether ovarian reserve markers are normal or low, with an AMH cutoff of 1.2 ng/mL and an AFC cutoff of 5.4 Its proposed measure of success is whether a cycle yields the number of eggs needed to get at least one chromosomally normal embryo.5
| Group | Age | Ovarian reserve tests | What it usually means for planning |
|---|---|---|---|
| 1 | Under 35 | Normal (AFC 5 or more, AMH 1.2 ng/mL or more) | Unexpectedly low egg yield; the protocol or dose may be the issue |
| 2 | 35 or older | Normal | Unexpectedly low yield plus age-related egg quality concerns |
| 3 | Under 35 | Low (AFC under 5 or AMH under 1.2 ng/mL) | Few eggs, but egg quality usually reflects younger age |
| 4 | 35 or older | Low | Few eggs and age-related quality decline; most trips per embryo |
The distinction matters abroad. A woman in group 3 and a woman in group 4 may both collect three eggs, but the chance that one of those eggs becomes a healthy embryo is very different. Ask which group the clinic places you in and what its own data show for patients like you.
What the outcome data look like
Published numbers for low responders vary enormously by age and by how "low" is defined, so treat any single figure with caution. ASRM summarizes US national data on about 5,000 IVF cycles in women with extremely low AMH (under 0.16 ng/mL):1
Two lessons follow. First, pregnancies do happen at the very bottom of the AMH range, which is why ASRM does not support refusing treatment. Second, cancellation and "no embryo" outcomes are common enough that your trip plan, budget and refund terms need to assume they can happen to you.
Protocol options: what ESHRE's stimulation guideline says
Clinics marketing to low responders often promote special protocols. ESHRE's ovarian stimulation guideline is the most thorough independent review of the evidence.26 The positions below come from its 2019 edition. ESHRE published an updated version in 2025, so ask your clinic whether its plan reflects the update and where it departs from it.7
| Approach | ESHRE position |
|---|---|
| Gonadotropin dose above 150 IU | Unclear whether it helps |
| Gonadotropin dose above 300 IU | Not recommended |
| GnRH antagonist vs agonist protocol | Equally recommended |
| Clomiphene alone or with gonadotropins | Equally recommended with gonadotropins alone |
| Letrozole added to gonadotropins | Probably not recommended |
| Modified natural cycle | Probably not recommended |
| Luteal-phase start of stimulation | Probably not recommended |
| Double stimulation in one cycle (DuoStim) | Research setting only |
| Birth control pill pretreatment | Not recommended with antagonist protocols |
The big takeaway is that no protocol reliably turns a low responder into a normal responder. Very high doses of stimulation drugs are not supported, which is worth knowing because medication is often one of the largest line items in a quote. ESHRE also rates protocols that use clomiphene as equal to gonadotropins alone for predicted poor responders, which may mean less injectable medication. Ask the clinic to price each option it offers you.2
Adjuncts: DHEA, growth hormone and the rest
Many clinics abroad sell add-on drugs to low responders. ESHRE reviewed the main ones and did not endorse any of them:2
| Adjunct | ESHRE 2019 position for poor responders |
|---|---|
| Growth hormone | Probably not recommended |
| DHEA | Probably not recommended |
| Testosterone | Probably not recommended |
| Aspirin | Not recommended |
| Sildenafil | Not recommended |
"Probably not recommended" means the evidence is weak or inconsistent, not that the drug is proven useless. Some specialists still use growth hormone or DHEA in selected cases. If a clinic includes an adjunct, it should be able to tell you why, what evidence it relies on, what it costs and whether you can decline it without losing your package price. A quote where several adjuncts are bundled in by default is a reason to ask more questions.
DHEA and testosterone are hormones. Do not start them on your own because a forum or a clinic brochure suggests it. Any adjunct should be prescribed by your treating doctor, who knows your history and other medications.
Several cycles, banking, and how many trips to expect
With low egg numbers, the realistic question is not "will this cycle work?" but "how many cycles might it take to get one or more transferable embryos?" That reframing changes how you plan travel and money.
Banking eggs or embryos
Some clinics offer to bank eggs or embryos over several retrievals before any transfer. This can make sense if you want to test embryos for chromosomal problems or need several embryos for more than one child. It also means more trips or a longer stay, more monitoring and more storage fees. Ask how long the clinic will store embryos and what local law allows; our guide to embryo storage limits by country covers the legal side.
Planning the trips
- Ask whether early monitoring scans and blood tests can be done at home so you arrive only for the final days and the retrieval. See our remote monitoring guide.
- Assume one cycle may be canceled. Book flexible flights and lodging where you can.
- Get the cancellation and refund policy in writing before paying, including what happens if only one follicle grows or no egg is collected.
- Ask whether a multi-cycle package discounts later cycles or simply locks you into the same clinic.
Cost per baby, not cost per cycle
A cheap single cycle is not good value if you are likely to need three of them. Compare clinics on the total cost to reach a transfer, including medication, monitoring, freezing, storage, embryo testing if you choose it, and repeat flights. Ask each clinic for a written quote that separates these items; you can also request a quote through us to compare line by line.
When donor eggs come into the conversation
For some people, especially in POSEIDON group 4 after repeated cycles with no usable embryos, donor eggs offer a much higher chance of pregnancy per transfer. That is a personal decision, and the timing is yours. A good clinic will raise it honestly, with your own results in hand, without pressuring you after a single low AMH test.
If you start thinking about it, donor egg availability, donor anonymity rules and waiting times differ sharply by country. Our donor egg IVF abroad guide walks through how the main destinations compare. Some people try one or two cycles with their own eggs at a clinic that also runs a donor program, so the switch, if it comes, does not mean starting over somewhere new.
Comparing clinics when your egg numbers are low
Headline success rates are usually dominated by younger women with normal ovarian reserve. They tell you little about your own chances. Ask for numbers that match your situation, and ask how they are counted.
- Send complete records. AMH with units and lab, AFC with the date and cycle day, previous stimulation protocols, doses, number of follicles and eggs, fertilization and embryo reports.
- Ask how they classify you. Bologna, POSEIDON, or their own definition, and why.
- Ask for outcomes in patients like you. Live births per cycle started, not just per transfer, for your age group and AMH range. Ask how many cycles were canceled.
- Ask what they would change. If you have had a poor cycle before, what specifically will they do differently, and what evidence supports it?
- Ask about every add-on. What it is, the evidence, the cost and whether it is optional.
- Get the money terms in writing. Cancellation refunds, multi-cycle pricing and storage fees.
If a clinic promises results that sound far better than the data above, ask how they define success and whether the figure includes canceled cycles. Your doctor at home can help you weigh the answers, and should remain part of your care while you plan.
