Information on this page is educational and does not replace a medical consultation. Outcomes depend on individual clinical factors. Every figure quoted below is attributed to a named registry or published study; none of them are Aansh success rates, and none of them predict your individual outcome.
Aansh Hospital & IVF Center is a government-registered Level-2 ART clinic (Reg. No. MH/AC/2024/15441/L2/Chandrapur/132), part of a growing network of fertility centers across Vidarbha and northern Telangana — and unlike a chain, where each centre's doctors decide independently, Dr. Shweta Agarwal holds final treatment authority for every cycle, at every location. Our headquarters and in-house embryology lab are in Chandrapur. Our government ART registration covers the full range of regulated ART services under the clinical leadership of Dr. Shweta Agarwal and embryology led by Aayush Agarwal, Ph.D..
Clinic websites tend to describe success and stay quiet about failure. That is unhelpful, because failure is the more common outcome of a single cycle — most people who start IVF do not have a baby from their first attempt, at any age. If you are reading this after a negative beta-hCG, that silence can leave you feeling like an exception when the published data says otherwise.
This page tries to fill the gap honestly: where in the cycle things actually stop, what your body does in the weeks afterwards, which investigations and protocol changes are and are not justified, what the cumulative data really shows for a second and third cycle, and what is known about conceiving without treatment afterwards. It promises nothing. It gives you the map that should have come with the cycle.
At what stage do most IVF fail?
Short answer: No registry publishes a single stage-by-stage attrition figure, so "most IVF fail at stage X" cannot be stated as a fact. What is documented is that among cycles reaching embryo transfer, most transfers do not result in a birth — 35% births per fresh embryo transferred at ages 18–34 down to 5% at 43–44 in the HFEA's 2022 preliminary UK data. Cycles also end earlier, at stimulation, retrieval, fertilisation or embryo development.
Those HFEA figures carry real restrictions and you should read them with the restrictions attached: they are preliminary (not yet validated), UK data, fresh transfers using the patient's own eggs, calculated per embryo transferred, and they exclude donor-egg, surrogacy and PGT cycles. They tell you about the transfer step, not about the whole cycle, and they are not directly transferable to an Indian clinic population.
It also matters that "failure after transfer" is not one thing. It covers at least three different outcomes, which have different explanations and different next steps:
- No implantation — the beta-hCG is negative; nothing implanted detectably.
- Biochemical pregnancy — hCG rose and then fell; implantation started but did not continue.
- Clinical miscarriage — a pregnancy was seen on scan and then was lost.
Ask your team which of these happened, because the follow-up differs. Below is the cycle as a sequence of checkpoints, with the questions each one raises. Treat the right-hand column as the conversation to have at your review, not as an automatic prescription.
| Stage | What has to happen | How a cycle stops here | What it raises for discussion |
|---|---|---|---|
| 1. Ovarian stimulation | Enough follicles grow on the injections | Cycle cancelled for poor response, or cancelled/frozen for over-response and OHSS risk | Protocol type and dose; reassessment of ovarian reserve |
| 2. Egg retrieval | Mature eggs are collected from those follicles | Fewer eggs than expected from the follicle count; immature eggs | Trigger drug and trigger timing |
| 3. Fertilisation | Sperm fertilises the eggs in the lab | Low fertilisation rate, or total fertilisation failure | ICSI if conventional IVF was used; repeat semen assessment; egg maturity |
| 4. Embryo development | Fertilised eggs divide and reach Day 3 / blastocyst | Embryos arrest before Day 5; nothing suitable to transfer or freeze | Culture review; egg and sperm factors. Note PGT-A cannot assess embryos that never reached blastocyst |
| 5. After transfer | The embryo implants and the pregnancy continues | Negative beta-hCG, biochemical pregnancy, or miscarriage | Which of the three occurred; embryo genetics; endometrium and cavity; any procedural difficulty at transfer |
Why do IVF transfers fail — and why do euploid embryos fail to implant?
Embryo chromosomal abnormality is regarded as a principal factor in implantation failure, and it increases with female age. Franasiak and colleagues, reviewing 15,169 consecutive trophectoderm biopsies (Fertility and Sterility, 2014), found aneuploidy rising predictably after age 26 and calculated the probability of a patient having no chromosomally normal blastocyst at all: 2–6% between ages 26 and 37, 33% at age 42 and 53% at age 44. Two limits on that study matter: it describes blastocysts that reached biopsy in a selected IVF population, and it does not establish the cause of any individual failed transfer.
It is also important not to over-read what genetic testing can do. The American Society for Reproductive Medicine's committee opinion on recurrent implantation failure states that although aneuploidy is believed to be a major contributor, PGT-A has not been shown to improve live-birth rates in general infertility populations or in recurrent implantation failure. Testing embryos does not diagnose every reason a transfer did not work.
When chromosomally normal (euploid) embryos still fail repeatedly, attention shifts to the uterus and the wider clinical picture: endometrial thickness and preparation, a cavity abnormality such as a polyp, fibroid, adhesion or septum, endometriosis or adenomyosis, hydrosalpinx (a fluid-filled blocked tube), thyroid and prolactin abnormalities, poorly controlled blood sugar, and difficulty at the transfer itself. That pattern has its own name and its own guideline-based workup — see recurrent implantation failure. Both ESHRE and ASRM caution that a proportion of these failures remain unexplained, and advise against broad routine testing panels.
What is the hardest stage of IVF?
There are three honest answers to three different questions. Clinically, among cycles that get that far, the transfer-to-pregnancy step is where most attempts are lost. Physically, in our clinic patients most often describe the stimulation-to-retrieval phase as the demanding part — daily injections, repeated scans, and a procedure under sedation. Emotionally, most describe the two-week wait, because it is the stage where nothing can be done and no information arrives; the two-week wait guide covers that window. The last two are our clinical experience, not survey data.
Is it common for IVF to fail first time?
Short answer: Yes. In the University of New South Wales NPESU analysis of Australian women who started IVF in 2016–17 (reported by VARTA), most people did not have a baby after one stimulated cycle at any age — from 43–48% live births after a single cycle in the youngest groups, down to under a third from the late thirties onward.
A first negative result therefore does not by itself indicate that anything is unusually wrong. It means the attempt fell on the wrong side of odds that were never better than roughly one in two even at the most favourable ages. The useful question after a first failure is not "what is wrong with me" but "what did this cycle show that should change the next one".
Before the result: this page starts at the negative beta-hCG
There are no reliable early signs that a transfer has failed — cramping, spotting, bloating, breast tenderness, fatigue and having no symptoms at all occur in cycles that go on to be positive as well as in those that do not, and only the beta-hCG blood test answers the question; the day-by-day account is in positive signs after embryo transfer: Day 1 to Day 14. Do not stop progesterone on the basis of symptoms or a home test — everything below assumes your clinic has confirmed a negative result.
After failed IVF side effects: what happens to your body
Short answer: After the medications stop, hormone levels fall and a withdrawal bleed usually follows within a few days to about a week; it is often heavier than a usual period. Bloating and fluid retention from stimulation typically settle over one to two weeks, and most women see their cycle regularise within one to two menstrual cycles. Severe abdominal pain or distension, breathlessness, rapid weight gain, fever or very heavy bleeding need same-day medical review.
The detail below reflects the usual clinical course. Your protocol, your response to stimulation and any complications change the picture, so use it as orientation and confirm the specifics with your own team.
In the first week after the negative result. Oestrogen and progesterone support is stopped and a withdrawal bleed generally follows within a few days to about a week. It is commonly heavier, longer or more crampy than your usual period, because the lining was built up on medication. A sharp drop in mood in these days is common — part grief, part hormonal withdrawal.
Left over from stimulation and retrieval. Abdominal bloating, fullness and some fluid weight from stimulation usually settle over one to two weeks. The ovaries stay enlarged and tender for a period after retrieval, so return to vigorous exercise gradually and on your clinic's advice. Retrieval is a surgical procedure and, uncommonly, has its own complications — bleeding, infection or injury to nearby structures — which present as pain, fever or unwellness rather than as ordinary post-cycle discomfort.
Ovarian hyperstimulation syndrome (OHSS). OHSS is a recognised complication of stimulation. The RCOG's patient guidance describes mild cases as usually settling with rest and simple measures, and lists the features that need urgent assessment: worsening abdominal swelling and pain, vomiting that prevents drinking, shortness of breath, reduced urine output, rapid weight gain, or leg swelling and calf pain. In a cycle that did not result in pregnancy, OHSS generally settles sooner, because there is no pregnancy hCG to sustain it. Severe OHSS is an emergency at any stage of the process — do not wait for your follow-up appointment.
Return of periods and ovulation. For most women the cycle re-regulates within one to two menstrual cycles, and ovulation resumes in that period. If you have had no period at all six weeks after stopping medication, contact your clinic rather than waiting.
Other common, temporary effects. Injection-site bruising and small lumps that resolve over days to weeks; constipation and headaches associated with progesterone; disturbed sleep; breast tenderness that eases with the withdrawal bleed; and a level of exhaustion out of proportion to physical activity.
What an uncomplicated failed cycle is not expected to do. It is not expected to damage the uterus — although, as above, retrieval and transfer are procedures and rare complications exist. It is not expected to reduce your remaining egg reserve: a stimulation cycle recruits follicles from that month's cohort, which would otherwise have been lost, rather than drawing on future reserve. And the cycle itself is not expected to reduce your chance of conceiving later. What a failed cycle can do is reveal something about the underlying problem — that information is about your diagnosis, not damage caused by the treatment.
On cancer risk specifically: ASRM's 2024 guideline on fertility drugs and cancer concludes that the evidence is broadly reassuring, while noting that a possible association with ovarian and borderline ovarian tumours is difficult to separate from the effects of underlying infertility and endometriosis. That is a more accurate statement than a flat "no risk", and it is worth discussing with your clinician if you have a family history.
When to call rather than wait: fever, bleeding heavy enough to soak a pad an hour or more, severe or one-sided abdominal pain, breathlessness, calf pain or swelling, fainting, or no period six weeks after stopping medication.
"ivf fail hone ke bad side effects in hindi" — IVF fail hone ke baad kya hota hai
This is a common search phrasing among Hindi-speaking patients, so here is the same answer in direct terms. (A full Hindi version of this page is available at /hi/blog/ivf-failed-what-happens-next-stages-causes-options.)
After a failed IVF cycle the medicines are stopped, hormone levels fall, and a period — usually heavier than normal — arrives within a few days to about a week. Bloating and swelling from the injections settle over roughly one to two weeks, the ovaries return to their normal size, and the menstrual cycle generally regularises within one to two cycles, which is also when ovulation returns. Tiredness, low mood, headaches, constipation, breast tenderness and injection-site bruising are common and temporary. An uncomplicated cycle is not expected to harm the uterus, use up remaining egg reserve, or reduce your chance of conceiving later. Get same-day medical review — do not wait for the follow-up appointment — if there is severe abdominal pain or swelling, breathlessness, rapid weight gain, fever, or very heavy bleeding.
What investigations and protocol changes should come after a failed cycle?
A follow-up review is where the data your cycle generated gets read back to you. Ask for the stimulation monitoring record, the embryology report (eggs collected, mature eggs, fertilisation, Day 3 and Day 5 grades, what was frozen), and the transfer note.
Two principles before the table. First, investigation should follow an indication, not a reflex. After a single failed transfer, ESHRE and ASRM guidance does not support routine hysteroscopy, thrombophilia or immunological testing, parental karyotyping, antiphospholipid testing or endometrial receptivity assays — those belong to specific recurrent or risk-based indications. Second, several add-ons marketed after failed cycles have limited or absent evidence that they improve live births; ask of anything offered what it will change about your plan and what evidence supports it.
| Where the cycle stopped | Reasonable next step | Usually reserved for a specific indication |
|---|---|---|
| Poor stimulation response | Review of ovarian reserve markers — AMH, antral follicle count, FSH; thyroid and prolactin if not recent. See AMH and ovarian reserve testing | Adjuvants and unproven "ovarian rejuvenation" treatments |
| Fertilisation failure | Repeat semen analysis; review of egg maturity; ICSI in a subsequent cycle if conventional IVF was used | Sperm DNA fragmentation testing — considered in selected cases such as repeated poor embryo development or unexplained failure, not routinely |
| Embryos arresting before blastocyst | Review of laboratory culture and of egg and sperm factors — see blastocyst culture | PGT-A does not help here: embryos that arrest never reach the blastocyst stage at which biopsy is possible |
| Negative beta-hCG after a good-quality transfer | Confirm what the endometrium and transfer notes showed; discuss whether to use frozen embryos in a frozen embryo transfer | The full recurrent implantation failure workup, including hysteroscopy — indicated after repeated failures or a suspicious finding on scan, not after one |
| Biochemical pregnancy or clinical miscarriage | Thyroid function and blood sugar; review the pregnancy timeline in detail | Parental karyotype, antiphospholipid and thrombophilia screening, products-of-conception testing — indicated for recurrent loss or specific risk factors. See recurrent pregnancy loss |
Questions to ask your doctor after a failed IVF
- At which stage did this cycle actually stop — and if it was after transfer, was it no implantation, a biochemical pregnancy, or a miscarriage?
- How many eggs were retrieved, how many were mature, how many fertilised, and how many reached blastocyst?
- What were the embryo grades, and do we have anything frozen?
- What was my endometrial thickness and pattern at transfer, and was the transfer technically straightforward?
- Was the stimulation response what you expected for my AMH and antral follicle count?
- What specifically would you change in the next cycle, and why?
- Which investigations do you recommend now, what is the indication for each, and what will each one change?
- Given my age and these results, what is a realistic expectation for the next attempt?
IVF success rate second time: chances of IVF working second time and third time
Short answer: There is no single second-attempt figure. The most useful published data is cumulative: the University of New South Wales NPESU analysis reported by VARTA, covering Australian women who started IVF in 2016–17 and were followed for three to four years, gives the chance of having had a baby by the end of one, two or three stimulated cycles, by age at the first cycle.
| Age at first cycle | After 1 cycle | After 2 cycles | After 3 cycles |
|---|---|---|---|
| Under 30 | 43% | 59% | 66% |
| 30–31 | 48% | 61% | 67% |
| 32–33 | 44% | 60% | 67% |
| 34–35 | 40% | 54% | 61% |
| 36–37 | 32% | 44% | 50% |
| 38–39 | 22% | 32% | 38% |
| 40–41 | 13% | 21% | 25% |
| 42–43 | 6% | 10% | 11% |
| 44+ | 2% | 5% | 5% |

Three things to read carefully.
These are cumulative figures, not the odds of your second attempt. The table describes the proportion of women who had had a baby by the end of one, two or three cycles. It does not report the conditional probability that cycle two succeeds given that cycle one failed — that number is not what was published, and quoting the "after 2 cycles" figure as a second-cycle success rate overstates it.
A stimulated cycle includes all the transfers arising from it. All transfers using embryos from one egg collection — fresh and frozen — belong to that stimulated cycle in this counting. So if your next step is a frozen transfer using embryos from your first retrieval, that is another transfer attempt, but it is not the "second cycle" in the table.
The numbers still increase across cycles, with diminishing increments. In each age band the increase from one cycle to two is larger than from two to three. That is a description of what the cohort did, not a promise about what repetition will do for any individual.
One practical point on cost and effort: if you have embryos frozen from the first stimulation, the next attempt is a frozen embryo transfer rather than a full cycle — no stimulation injections, no retrieval, no anaesthesia, and lower cost. The HFEA's 2022 preliminary data records the average UK birth rate from frozen transfers rising from around 15% in 2012 to around 30% in 2022 as freezing techniques improved. Ask whether a FET is your next step before assuming another full cycle. Our IVF cost and 0% EMI page sets out the price bands for each.
How long should I wait after a failed IVF cycle?
Physically, in the absence of OHSS or another complication, treatment can commonly resume after one to two natural menstrual cycles — roughly four to eight weeks — and a frozen transfer is often scheduled sooner than a fresh cycle. If a procedure such as hysteroscopy, or treatment for a hydrosalpinx, endometriosis, thyroid or metabolic problem is planned, the timing follows that rather than a fixed interval. Your own clinic's advice takes precedence over any general figure, because it accounts for your protocol and your recovery.
Emotionally, there is no correct interval. Some couples want the next cycle booked before they leave the follow-up appointment; others need months. Both are reasonable. Where delay does carry a measurable cost — significantly reduced ovarian reserve, or age in the early forties, where per-cycle chances decline with time — your clinician should say so plainly rather than let you find out later. You are entitled to know whether time is a clinical variable in your particular case.
Has anyone got pregnant naturally after failed IVF?
Short answer: Yes — conception without treatment after unsuccessful IVF is documented in cohort studies, though it is a possibility rather than a plan. In a Scottish cohort of 2,133 women treated between 1998 and 2011, 17% of those whose treatment had been unsuccessful had a treatment-independent live birth within five years of their last embryo transfer.
Two published cohorts are worth knowing about:
- The Scottish cohort (2,133 women, IVF/ICSI 1998–2011) reported that within five years of the last embryo transfer, 17% of women whose treatment was unsuccessful — and 15% of women whose treatment had resulted in a live birth — had given birth after conceiving without treatment. Shorter duration of infertility, younger female age, and IVF rather than ICSI were associated with a higher likelihood.
- The French DAIFI study (Troude and colleagues) followed 6,507 couples who began IVF in 2000–02 across eight centres. Eight years on, 71% had a child: 41% through IVF at the centre, 7% after treatment elsewhere, 12% by spontaneous conception and 11% through adoption. Among couples who left ART after unsuccessful treatment and responded to follow-up, about a quarter subsequently had a spontaneous birth. As with any long-term questionnaire follow-up, couples who responded may differ from those who did not, so treat the exact proportion with caution.
Both cohorts describe European populations from earlier treatment eras, and neither says that IVF itself improves subsequent natural fertility. Spontaneous conception is more plausible where infertility was unexplained or mild and the duration was short, and much less so with bilateral tubal blockage, severe male factor or azoospermia, where the underlying barrier does not change.
Are you more fertile after an IVF cycle? There is no good evidence that IVF makes the following months more fertile. What does change is that problems get diagnosed and treated along the way and that ovulation resumes normally afterwards. Keep trying naturally between cycles unless your doctor has advised otherwise — and if your family is complete, use contraception, because these pregnancies are common enough to be genuinely unplanned.
Recovering emotionally, and deciding what comes next
A failed cycle is a loss and deserves to be treated as one rather than as a scheduling problem. Grief, anger, numbness and the particular difficulty of not knowing why are ordinary responses, and in our experience most couples go through some version of them. We have written separately about that side of it — see coming to terms after a failed IVF cycle — including what happens when partners grieve at different speeds, and when a fertility counsellor is worth seeing.
Alongside time, what helps most is information: which stage stopped, what will be different next time, and what the realistic numbers are. That is the purpose of the follow-up review, and the reason this page exists.
If your cycle failed elsewhere and you want an independent read of what happened, we can help. Aansh offers a free second-opinion review for couples who have completed at least one IVF cycle at another centre. Bring everything: the stimulation monitoring chart, the embryology report with fertilisation numbers and embryo grades, the transfer note, and both partners' investigation reports. Dr. Shweta Agarwal will go through the cycle stage by stage and tell you what she would change — including when the honest answer is that the previous protocol was reasonable and another attempt is the right step. We are in Chandrapur, with our own on-site embryology lab, and we see couples from across Vidarbha. Call +91 80056 85160 or message us on WhatsApp.
