The call usually comes the evening of the retrieval. The nurse says the number, three eggs, or two, sometimes one, and the woman on the other end goes quiet. She had psyched herself up for the injections, the scans, the two weeks of her life rearranged around this cycle. She was not prepared for the number to be this small.
If you are reading this after a retrieval like that, or your fertility clinic has just told you that you are likely to be a “poor responder” before you have even started, I want to walk you through what this actually means. Not the worst-case version you may have already found on a forum at 1 a.m., the clinical picture.
I’m Dr. Suganya Venkat, an OB-GYN with over fifteen years of experience, and this is one of the harder conversations I have with women at Fertilia. It is also one where the facts are genuinely more workable than the fear suggests. A poor response tells your clinic something useful about the next cycle. It is information, not a verdict.
This guide covers what poor ovarian response actually means by clinical definition, why it happens, what a clinic can realistically adjust for the next attempt, where donor eggs enter the conversation honestly, and how to hold the emotional weight of this news while you decide what comes next.
What “Poor Ovarian Response” Means
Poor ovarian response, often shortened to POR, describes how your ovaries respond to the stimulation medications in an IVF cycle, not a permanent statement about your fertility. It is measured by the number of eggs retrieved after your ovaries have been stimulated with gonadotropins, not by AMH or antral follicle count alone. Those tests predict response before the cycle. Poor response is what actually happened during it.
The most widely used clinical definition is the Bologna criteria, set by the European Society of Human Reproduction and Embryology (ESHRE) in 2011. A woman is classified as a poor responder if she meets at least two of the following three features (Ferraretti et al., Human Reproduction, 2011, PMID 21505041):
- Advanced maternal age (40 or above) or another known risk factor for poor response, such as previous ovarian surgery or chemotherapy
- A previous poor response, defined as three or fewer eggs retrieved with a conventional stimulation protocol
- An abnormal ovarian reserve test, typically an antral follicle count under 5 to 7 or an AMH under roughly 0.5 to 1.1 ng/mL
Notice what this definition does not require: it does not require you to be over 40. A 32-year-old with a low AFC who retrieves two eggs on a standard protocol meets the criteria just as much as a 43-year-old does. This surprises a lot of women, and understandably so. Age is one path into this category, but not the only one.
A more recent framework, POSEIDON, refines this further. Published in 2016 (Poseidon Group, Alviggi et al., Fertility and Sterility, PMID 26921622), the POSEIDON criteria separate poor responders into four groups based on age, ovarian reserve markers, and whether the poor response was expected going into the cycle or came as a surprise. A 33-year-old with a normal AFC who unexpectedly yields three eggs (POSEIDON group 1) is a genuinely different clinical situation from a 38-year-old whose AFC already predicted a low yield (POSEIDON group 4), even though both would be called “poor responders” under the older Bologna definition. This distinction matters because it changes what your clinic will try next, and how much that adjustment is likely to help.
If your report used the word “poor responder” without explaining which category you fall into, that is a reasonable thing to ask your clinic directly at your next visit.
Why Poor Response Happens
Age is the most common driver, but not the only one. The number of follicles that can be recruited in a given cycle declines with age, most steeply after 35 and again after 38. This is a supply issue, the pool of resting follicles shrinks over time, and no stimulation protocol can recruit follicles that are not there.
Diminished ovarian reserve independent of age. Some women in their late 20s or early 30s have a lower starting reserve than expected for their age, sometimes called premature ovarian insufficiency when it is significant. This can run in families, and a mother’s or sister’s early menopause is a useful detail to mention to your clinic if you have not already.
Previous ovarian surgery. Surgery for endometriomas, dermoid cysts, or other ovarian cysts can reduce the pool of follicles in the operated ovary, particularly if a large portion of ovarian tissue was removed alongside the cyst. This is one of the “known risk factor” pathways in the Bologna criteria, and it is worth mentioning explicitly if you have had ovarian surgery in the past, even years ago.
Genetics. Certain chromosomal patterns, including being a carrier for the FMR1 premutation associated with Fragile X, are linked to earlier decline in ovarian reserve. This is uncommon, but if poor response happens at a younger age with no other explanation, your clinic may suggest genetic testing.
Unexplained. Sometimes a full workup finds nothing. No surgery, no family history, no genetic flag, simply a lower-than-expected reserve or response. This is frustrating to sit with because there is no single thing to point to, but it does not change what the honest next steps are.
Chemotherapy or radiation exposure. Certain cancer treatments are directly toxic to ovarian follicles, which is why fertility preservation before treatment is now a standard conversation in oncology care where it is available.

What Your Clinic Can Adjust for the Next Cycle
This is the part of the conversation that gets skipped too often, because a poor response is upsetting to hear and the appointment moves on before the “what now” gets covered properly. Here is what genuinely changes between cycles for a poor responder.
Protocol changes. Fertility specialists commonly try switching between an antagonist and an agonist protocol, or adjusting the timing and dose within the same protocol type, based on how your ovaries responded the first time. There is no single protocol proven superior for every poor responder; the adjustment is individualised to what your specific cycle showed.
Dose adjustments. A higher gonadotropin dose is sometimes tried, though past a certain point, more medication does not recruit more follicles if the follicle pool itself is the limiting factor. Your clinic will weigh this against the cost of higher-dose medication and the physical toll of a more intensive stimulation.
Adjunct therapies, honestly scoped. DHEA and coenzyme Q10 are the two adjuncts with the most research behind them for poor responders, and it is worth being precise about what that research actually shows.
A randomised controlled trial of DHEA supplementation in poor responders found improved pregnancy rates when DHEA was given before and during the IVF cycle (Wiser et al., Human Reproduction, 2010, PMID 20729538). A separate randomised trial of coenzyme Q10 pretreatment in young women with decreased ovarian reserve found a higher number of retrieved oocytes and better embryo quality with CoQ10 compared to no pretreatment (Xu et al., Reproductive Biology and Endocrinology, 2018, PMID 29587861).
Both are reasonable to discuss with your fertility specialist. Neither is a guarantee, and neither reverses the underlying reserve. Think of them as adjuncts that may modestly improve the odds within a cycle, not a fix for the reserve itself. Any supplement should be started under your clinic’s guidance, timed correctly before your next stimulation begins.
Mild or minimal stimulation protocols. For some poor responders, a gentler stimulation approach using lower medication doses is tried instead of pushing for a higher dose. The logic is that if the ovary is only ever going to recruit a small number of follicles regardless of dose, a lower-intensity approach can retrieve a similar yield with less medication cost and less physical strain.
Accumulating oocytes or embryos across cycles. When each individual cycle yields only one to three eggs, some clinics will freeze eggs or embryos across two or three consecutive cycles and combine them before attempting a transfer, rather than transferring from a single low-yield cycle. This is a legitimate strategy worth asking about directly, since it changes how you think about the number from any one retrieval.
None of these guarantee a different outcome. What they represent is that a poor response in one cycle is a data point your clinic uses to plan the next one differently, not a reason to expect the same result every time.
When Donor Egg Becomes the Honest Next Conversation
For some women, after one or more cycles of poor response with adjusted protocols still yielding very few eggs or poor-quality embryos, donor eggs become the more honest conversation to have. This is not a failure of anything you did. It usually means the ovarian reserve itself, not the protocol, is the limiting factor, and no amount of protocol adjustment recruits follicles that are not there.
This is a significant decision, and it deserves its own careful conversation rather than a rushed mention at the end of a difficult retrieval day. I have written a complete guide covering who this genuinely applies to, how it works under Indian ART Act rules, and current 2026 costs and success rates: Donor Egg IVF in India: What to Know, Cost & Success Rates.

Sitting With the Diagnosis
I want to say this plainly, because I see how much silent weight women carry after a poor response: this number is not a verdict on you, your body, or your worth as a mother. It is one piece of clinical information gathered at one point in time, under one specific protocol.
It is also completely normal to grieve it. Many women describe a poor response as feeling like a door closing, even while their clinic is telling them there are more paths. Both things can be true: the news is genuinely hard, and there are genuinely more options ahead. You do not have to rush from the first feeling to the second one in the same appointment.
If you are the partner or family member of a woman going through this, the most useful thing you can offer is usually not reassurance about outcomes, since none of us can promise those, but steady presence while she processes the news at her own pace.
At Fertilia, poor ovarian response is one of the situations where I work alongside a woman’s existing fertility specialist rather than replacing that relationship. Your IVF clinic manages the stimulation protocol and retrieval. My role, and the role of our Fertility and IVF Support programs, is the layer around that: making sure the rest of your health, from thyroid function to vitamin D to stress load to sleep, is not adding an avoidable obstacle on top of an already difficult picture, and helping you think clearly about the decisions in front of you.

Frequently Asked Questions
What is considered a poor ovarian response in IVF? Under the Bologna criteria, poor ovarian response is defined as meeting at least two of three features: advanced maternal age (40 or above) or another risk factor for poor response, a previous cycle retrieving three or fewer eggs on a conventional protocol, or an abnormal ovarian reserve test such as a low AFC or low AMH. You do not need to be over 40 to meet this definition; a younger woman with a low reserve marker and a prior low-yield cycle can meet it too.
Does poor ovarian response mean I have a low chance of pregnancy? It means your chance per retrieved egg is not different from anyone else’s, but you may have fewer eggs to work with per cycle, which affects the odds within a single attempt. It does not tell you anything about egg quality, only quantity. Many women with a poor response history do go on to conceive, sometimes by adjusting the protocol, sometimes by accumulating across cycles, and sometimes with donor eggs. The right next step depends on your specific numbers and history, not a general statistic.
Can poor ovarian response improve with treatment? The underlying reserve, the number of follicles remaining, does not increase with treatment. What can improve is the yield your clinic gets from the follicles that are there, through protocol adjustments, dose changes, or adjuncts like DHEA or CoQ10, which have shown benefit in some randomised trials. Think of it as optimising the response, not reversing the reserve.
Should I try a different IVF clinic after a poor response? Not automatically. A poor response is often a predictable outcome of your ovarian reserve rather than a reflection of your clinic’s skill, and switching clinics does not change your underlying biology. What is worth doing is having a direct conversation with your current clinic about which POSEIDON group you fall into and what specifically they plan to change for the next cycle. If that conversation feels rushed or generic, a second opinion is reasonable, but the decision should be about the plan, not a reflexive switch.
How many eggs are needed for a reasonable chance at pregnancy in IVF? There is no fixed number that guarantees anything, since embryo quality and uterine factors matter as much as egg count. But broadly, more eggs retrieved gives more chances for at least one to fertilise, develop normally, and result in a viable embryo. This is exactly why some clinics recommend accumulating eggs or embryos across two or three low-yield cycles before attempting a transfer, rather than working from a single small cohort.
Is DHEA or CoQ10 safe to take before starting my next IVF cycle? Both have research behind them specifically in poor responders, but they should be started under your fertility specialist’s guidance, at the correct dose and timing before stimulation begins, not self-initiated from an online recommendation. Your clinic will also want to confirm there is no reason in your specific case, such as certain hormone-sensitive conditions, to avoid DHEA.
When should I consider donor eggs instead of continuing with my own? This conversation usually comes up after one or more cycles of adjusted protocols still yield very few eggs or consistently poor-quality embryos, particularly when combined with advanced age or a significantly reduced reserve. It is a decision worth making deliberately rather than under pressure, ideally after your clinic has genuinely tried the adjustments available for a poor responder. Our complete guide to donor egg IVF in India covers who this applies to, the legal framework, and current costs.
