Failed IVF with Good Embryos – 6 Questions to Ask Your Doctor
By Dr. Ashish Soni | Metro IVF Test Tube Baby Center, Ambikapur | metrofertility.in
Of all the scenarios a couple can face in IVF, this one is among the most bewildering and the most painful: the embryos were good. The doctor confirmed it. Grade A blastocysts, the embryologist said. Perfect development. Everything looked exactly as it should.
And then — nothing. No pregnancy. No implantation. The transfer happened, the two-week wait happened, and the blood test came back negative.
When a cycle fails with poor embryos, there is at least a clinical explanation — the embryo quality was not sufficient. When a cycle fails with good embryos, the explanation is harder to find and harder to accept. The part of the process that was supposed to be the hardest — creating viable embryos — worked. And the part that should have followed naturally — implantation — did not.
The question that consumes every couple in this situation is the same: if the embryos were good, why didn't it work? And the answer — which most clinics provide inadequately, if at all — is that good-looking embryos and good-quality embryos are not always the same thing, and that the uterine environment into which even a genuinely good embryo is transferred must be precisely right for implantation to occur.
Finding the real answer requires asking the right questions. This article gives you exactly those questions — six specific, medically grounded questions that every couple should ask their doctor after failing IVF with apparently good embryos. The answers to these questions will tell you more about the real reason your cycle failed — and what needs to change before the next one — than any generic explanation your clinic may have offered.
Why "Good Embryos" Is Not the Complete Picture
Before the six questions, one concept deserves to be clearly established — because it shapes the entire conversation that follows.
When an embryologist describes an embryo as "good," they are making a morphological assessment. They are describing what the embryo looks like under the microscope — its cell number, the regularity of its cell division, its degree of fragmentation, and in the case of blastocysts, the development and compaction of its inner cell mass and trophectoderm. These are visible, assessable features that correlate broadly with developmental competence.
But morphological appearance is an imperfect proxy for the quality that truly matters — chromosomal integrity and developmental viability. An embryo that looks perfect under the microscope can carry chromosomal abnormalities that make it incapable of sustaining implantation. An embryo that reaches blastocyst stage with good morphology can carry unrepaired sperm DNA damage that compromises its post-implantation development. The microscope reveals the outside of the embryo. It cannot reveal the genetic content within.
This is why the phrase "we had good embryos" is the beginning of the clinical conversation after a failed IVF cycle — not the end of it. Good morphology increases the probability of a viable embryo but does not guarantee it. And when good-morphology embryos fail to implant, the investigation must look both at the embryo — with tools that go beyond morphology — and at the uterine environment into which it was transferred.
The six questions below address both.
Question One: Were the Embryos Tested for Chromosomal Abnormalities?
This is the most important question to ask after a failed cycle with apparently good embryos — and it is the question whose answer most frequently reveals the gap between "looks good" and "is genetically viable."
Preimplantation genetic testing for aneuploidies — PGT-A — is a technique that examines the chromosomal content of an embryo before transfer. It identifies embryos that carry the correct number of chromosomes — euploid embryos — and distinguishes them from embryos that carry chromosomal abnormalities — aneuploid embryos — that cannot sustain a pregnancy.
The critical insight is this: an aneuploid embryo can have perfect morphology. It can reach blastocyst stage with an excellent inner cell mass and a well-expanded trophectoderm. An embryologist scoring it without PGT-A information would grade it as top quality. And when transferred, it will fail to implant — or will implant briefly and result in an early miscarriage — because its chromosomal content is incompatible with continued development.
The proportion of embryos that are chromosomally abnormal increases with maternal age — from approximately 20 to 25 percent in women under 30 to over 50 percent in women over 38. But chromosomal abnormalities occur at all ages, and in some couples the rate of aneuploidy is higher than expected for the woman's age.
If previous transfers involved embryos that were not PGT-A tested — which is the case at most clinics in India where PGT-A is not routine — the question of whether those embryos were chromosomally normal is unanswered. And if they were aneuploid, no amount of uterine preparation or protocol adjustment will produce a different outcome from transferring another aneuploid embryo.
The right next step, when this question has not been answered, is to discuss PGT-A testing for future embryos — understanding both its potential benefit in selecting chromosomally normal embryos for transfer and its limitations, including the small risk of misdiagnosis and the cost. The decision about whether PGT-A is appropriate for a specific couple depends on their age, embryo history, and clinical context — a conversation that Dr. Soni has with every couple for whom it is relevant.
Question Two: Was My Uterine Cavity Fully Assessed Before Transfer?
The second question shifts focus from the embryo to the environment into which it was transferred — and it is a question whose answer reveals the most commonly missed structural cause of implantation failure.
The uterine cavity must be free of abnormalities for an embryo to implant successfully. Polyps — benign growths of endometrial tissue — can physically obstruct implantation or alter the local hormonal environment of the endometrium in ways that reduce receptivity. Submucosal fibroids — fibroids that protrude into the uterine cavity — compress and distort the endometrial surface and impair blood flow to the lining. Intrauterine adhesions — scar tissue formed after surgery, infection, or trauma — replace normal endometrial tissue with fibrous material that cannot participate in implantation. Uterine septum — a band of tissue dividing the cavity — creates an area of poor vascularity that is inhospitable to embryo attachment.
All of these conditions can be present without causing noticeable symptoms. Many of them are not reliably detected on standard pelvic ultrasound. The only way to definitively assess the uterine cavity is through hysteroscopy — the direct visual examination of the cavity using a thin camera passed through the cervix.
If hysteroscopy was not performed before your transfer — and at many IVF clinics it is not performed routinely — the uterine cavity was not fully assessed. A condition that could be silently preventing implantation may be present and unidentified.
The appropriate response to a failed cycle with good embryos, when hysteroscopy has not been performed, is to schedule hysteroscopy before the next transfer. If an abnormality is found, it should be corrected — through hysteroscopic surgery — before any embryo is transferred. The improvement in implantation rates following correction of uterine cavity abnormalities is well documented and can be substantial.
Question Three: Was My Embryo Transfer Timed to My Personal Implantation Window?
This question surprises many patients — because the assumption embedded in standard IVF practice is that the implantation window is the same for every woman, and that timing the transfer to a standard protocol is sufficient.
It is not — for every woman.
The implantation window is the specific period during which the endometrium is capable of accepting and sustaining an embryo. In the vast majority of women, this window occurs at a predictable time relative to progesterone exposure — in a standard frozen embryo transfer protocol, approximately five days after progesterone is started for a blastocyst transfer. The standard protocol is timed to this average.
But a significant minority of women — studies suggest somewhere between 20 and 30 percent of women with recurrent implantation failure — have an implantation window that is displaced. Their window opens one or two days earlier or later than the standard assumed timing. When transfers are performed at the standard time for a woman whose window is displaced, the embryo arrives in the uterus when the endometrium is not yet receptive — or has already closed its receptivity — and implantation fails. Consistently.
This displacement is invisible to standard monitoring. Ultrasound assessment of lining thickness and pattern cannot detect it. It requires ERA testing — Endometrial Receptivity Analysis — a test that examines the gene expression pattern of the endometrial tissue at the assumed time of transfer and determines whether the endometrium is genuinely in its receptive phase at that moment.
If the ERA reveals a displaced window, subsequent transfers are timed to the personalized window rather than the standard protocol. The improvement in implantation rates in ERA-identified displaced-window patients who subsequently transfer at their personalized time is consistently reported in the literature as significant.
If ERA testing has not been discussed or performed after your failed transfers, and particularly if multiple transfers of good-quality embryos have all failed without a structural or embryological explanation, this question is one of the most important you can ask.
Question Four: Has My Husband's Sperm DNA Fragmentation Been Tested?
As the previous article in this series established in detail, sperm DNA fragmentation is one of the most common and most consistently overlooked causes of repeated IVF failure with apparently good embryos — and it is entirely invisible to standard semen analysis.
An embryo created from high-DFI sperm can develop through the first three to five days of culture in a way that looks completely normal under the microscope — good morphology, good cell number, appropriate development pattern. The egg's DNA repair mechanisms sustain early development. But the underlying DNA damage, if severe enough, compromises the embryo's capacity for sustained implantation — and the embryo that received a top grade from the embryologist fails to implant when transferred.
The clinical picture that results — repeated transfers of morphologically excellent embryos, all failing to implant, with no structural uterine cause identified — is one of the most characteristic presentations of unrecognized high sperm DNA fragmentation. And it is a presentation that continues through cycle after cycle at clinics that never order the test.
If your husband's semen analysis has been described as normal but his sperm DNA fragmentation has never been specifically tested, the investigation is incomplete. The test is straightforward and should be performed as part of the re-evaluation after any failed cycle with good embryos — particularly when the male partner has risk factors including varicocele, significant smoking history, environmental toxin exposure, older age, or a history of genitourinary infection.
When high DFI is found and addressed — through antioxidant therapy, varicocele treatment, lifestyle modification, or testicular sperm extraction — subsequent cycles frequently produce embryos with better true developmental competence than the morphologically identical embryos from previous cycles. The appearance does not change. The underlying genetic integrity does.
Question Five: Were Any Measures Taken to Assess and Optimize Uterine Blood Flow?
This question addresses a dimension of endometrial preparation that is frequently overlooked in standard IVF protocols — the vascularity of the uterine lining.
An embryo does not implant into a passive surface. It implants into an actively vascularized, metabolically active tissue that must provide the nutritional and hormonal support necessary for the earliest stages of placental development. The blood supply to the endometrium — the density and pattern of its vasculature, the resistance of its feeding arteries — directly affects its receptivity to implantation.
Doppler ultrasound assessment of uterine artery blood flow provides information about the adequacy of uterine vascular supply. When blood flow resistance is high — indicating relatively poor blood delivery to the uterine lining — the endometrial environment may be suboptimal for implantation even when the lining appears adequate in thickness and pattern. This finding is associated with lower implantation rates and can be present in women who have no other identified cause of repeated failure.
Interventions to improve uterine blood flow — including low-dose aspirin, vaginal sildenafil, vitamin E, and pentoxifylline — have evidence supporting their use in improving endometrial vascularity and implantation rates in women with documented poor uterine perfusion. These are simple, low-risk additions to the transfer preparation protocol that can produce meaningful improvements in the endometrial environment.
If Doppler assessment of uterine blood flow was not performed during your endometrial preparation — and at many clinics it is not — the adequacy of your uterine vascularity was not assessed. Asking this question opens a dimension of investigation that may reveal a correctable contribution to implantation failure.
Question Six: Is There Any Evidence of Chronic Endometritis?
Chronic endometritis — a low-grade, persistent infection or inflammation of the endometrial lining — is one of the most frequently undiagnosed causes of repeated implantation failure, including in transfers of morphologically excellent embryos.
Unlike acute endometritis, which causes obvious symptoms including fever, pelvic pain, and abnormal discharge, chronic endometritis is typically silent. The woman has no significant symptoms. Standard pelvic ultrasound may show no abnormality. The endometrium appears on ultrasound to have reached adequate thickness with a normal trilaminar pattern. And yet the microscopic inflammatory environment of the lining — characterized by the presence of plasma cells that are not normally found in the endometrium — is hostile to implantation in ways that prevent even a chromosomally normal, morphologically excellent embryo from establishing a pregnancy.
The diagnosis of chronic endometritis requires endometrial biopsy — a small sample of endometrial tissue taken and examined histologically for the presence of plasma cells — and endometrial culture, to identify the specific organism responsible for the infection. The treatment — targeted antibiotic therapy directed at the identified organism — resolves the infection in most cases and restores normal endometrial function.
Studies examining the prevalence of chronic endometritis in women with repeated implantation failure have found it in approximately 30 percent of cases — meaning that in roughly one in three women with unexplained repeated implantation failure, a treatable infection is contributing to the failure. Treatment of chronic endometritis before subsequent transfers significantly improves implantation rates in these patients.
If endometrial biopsy for chronic endometritis has not been discussed or performed after your failed transfers with good embryos, this question may lead to the diagnosis of a condition that is entirely treatable — and whose treatment may change the outcome of your next transfer substantially.
What to Do With the Answers
These six questions are not merely conversational. They are diagnostic tools. The answers your doctor gives — or cannot give — will tell you two things.
First, they will reveal which investigations have not been performed — and which gaps in your clinical work-up may be allowing a treatable cause of failure to remain unidentified. Every question above corresponds to a specific, performable investigation. If the answer to any question is "no, that has not been done," that investigation should be performed before the next transfer cycle begins.
Second, they will reveal the depth of clinical thinking being applied to your case. A doctor who can answer each question specifically — with reference to your actual cycle data, your individual test results, and a clear explanation of what was found and what was not — is a doctor who has engaged thoroughly with your case. A doctor who responds with generalities, who deflects the questions, or who cannot explain why specific investigations were or were not performed, is a doctor whose approach to your care may not be sufficiently individualized for the complexity of your presentation.
Both pieces of information are valuable. Both inform the most important decision you will make after a failed cycle with good embryos: what to do next, and with whom.
If the Answers Leave You With More Questions Than Before
It is not unusual for couples who ask these questions to find that several of them have not been addressed — that hysteroscopy was not performed, that PGT-A was not discussed, that ERA was never mentioned, that sperm DNA fragmentation was never tested, that uterine blood flow was never assessed, and that chronic endometritis was never investigated.
When this is the case, the appropriate next step is a comprehensive re-evaluation with a specialist who has specific experience in failed-implantation cases — someone who will not simply recommend another cycle with the same protocol, but will conduct the thorough investigation that your case requires before any further transfer is attempted.
At Metro IVF in Ambikapur, Dr. Ashish Soni conducts exactly this re-evaluation for couples with repeated failed transfers of good embryos. Every previous cycle is reviewed in detail. Every investigation that has not been performed is identified. A complete, individualized work-up is conducted — covering all six dimensions addressed by the questions in this article, and any additional factors suggested by the clinical history. And a treatment plan is built specifically around what that work-up actually finds.
The couples who come to Metro IVF after multiple failed transfers of good embryos — some of them carrying years of unexplained failure and the emotional weight of hope repeatedly raised and dashed — frequently receive, for the first time, a specific, evidence-based explanation for why their transfers did not work. And with that explanation comes a genuinely different approach to the next cycle — one designed around the real cause of failure rather than around the assumption that the previous protocol was correct.
That explanation, and that different approach, is what makes the next cycle different. Not luck. Not hope. Investigation, followed by the right treatment for what the investigation actually finds.
Your Next Step
If you have had IVF fail with good embryos and the explanation you received was insufficient — if none of the six questions above were fully addressed, if the investigation that should have followed your failure has not happened — you deserve a more thorough conversation than you have had so far.
Book a consultation with Dr. Ashish Soni at Metro IVF in Ambikapur. Bring every report from every previous cycle — the stimulation monitoring records, the embryology grading reports, the transfer records, the blood test results. Dr. Soni will review all of it, identify what has been missed, and give you an honest, specific, and actionable assessment of what needs to happen before your next attempt.
The embryos were good. The question of why they did not implant deserves a good answer.
