Good embryos failing to implant is called Recurrent Implantation Failure (RIF). There is almost always a reason — chromosomal errors in embryos, a uterine cavity problem missed on 2D scan, the wrong transfer timing (ERA test), sperm DNA damage, immune factors, or a hydrosalpinx silently halving your success rate. A systematic investigation at Mother Hospitals identifies the cause — and fixing it makes the next cycle fundamentally different. Call 97059 93366 to book a second opinion consultation.
Each has a specific investigation and a specific treatment — not "try again and hope"
Embryos that look perfect under the microscope are chromosomally abnormal in 40–70% of cases — especially in women over 35. These embryos fail to implant or miscarry early. Standard IVF cannot distinguish normal from abnormal embryos visually.
✓ Fix: PGT-A — genetically test embryos, transfer only normal ones
Polyps, submucosal fibroids, Asherman's adhesions, or endometritis (uterine infection) — often invisible on standard 2D ultrasound but clearly seen on hysteroscopy. A single small polyp can halve implantation rates. Many IVF patients have never had a hysteroscopy.
✓ Fix: Hysteroscopy — diagnoses and treats in one procedure
The endometrium is receptive for only a narrow window (approximately 12–24 hours). In 30% of women with failed implantation, this window is "displaced" — earlier or later than the standard protocol assumes. Embryos transferred at the wrong time cannot implant even if perfect.
✓ Fix: ERA test → personalised transfer timing
A blocked, fluid-filled fallopian tube continuously leaks toxic fluid back into the uterine cavity — poisoning the embryo at the time of implantation. Reduces IVF success by 50%. Critically: hydrosalpinx can be missed on routine 2D ultrasound and only seen on careful 3D scan or hysteroscopy.
✓ Fix: Salpingectomy (remove tube) before next IVF — restores full success rate
Normal semen analysis (count, motility, morphology) does not rule out sperm DNA damage. High DNA fragmentation causes fertilisation and initial cell division — but then embryo development stalls at Day 3–5, or embryos appear poor quality. Often blamed on egg quality when sperm is the actual cause.
✓ Fix: DFI test → antioxidants, IMSI, or testicular sperm (TESA)
Elevated Natural Killer (NK) cell activity, HLA-C incompatibility, or other immune mechanisms can cause the body to reject embryos as foreign tissue. Suspected when: all embryos are chromosomally normal (PGT-A confirmed), cavity is clear (hysteroscopy done), ERA timing is correct — yet implantation still fails.
✓ Fix: Prednisolone, intralipid infusion, hydroxychloroquine
APS (antiphospholipid syndrome) and inherited clotting disorders (Factor V Leiden, MTHFR) can cause microscopic clots in placental vessels at the time of implantation — preventing the embryo from establishing blood supply. More often associated with miscarriage than failure to implant, but both patterns occur.
✓ Fix: Low-molecular-weight heparin + aspirin from embryo transfer day
Suboptimal stimulation (poor egg numbers or quality), wrong trigger timing, premature progesterone rise during stimulation, poor lab culture conditions, freeze-thaw damage — all affect outcome. A critical review of every previous cycle's data often reveals adjustable factors that were not optimised.
✓ Fix: Full cycle review, protocol redesign, experienced embryology team
A systematic workup finds the cause in most cases — done before designing the next cycle
Direct visualisation of the uterine cavity. Identifies polyps, fibroids, adhesions, septum, and endometritis — all invisible on 2D ultrasound. Recommended for all women with 2+ failed IVF cycles regardless of previous scan results.
When: before next IVF cycle
Endometrial Receptivity Analysis — biopsy of the uterine lining at standard transfer time. Gene expression profile determines if your implantation window is on time, early, or late. A personalised transfer time is given for the next FET cycle.
When: after 2–3 failed FET cycles with good embryos
If PGT-A has not been done in previous cycles, planning it for the next cycle is the single highest-yield change. Ensures only chromosomally normal embryos are transferred — eliminating the most common cause of IVF failure.
When: especially if age >35 or all previous embryos were untested
DFI (DNA Fragmentation Index) test on ejaculated sperm. If DFI >25%, treatment is: antioxidant course (3 months), IMSI (very high magnification sperm selection in IVF lab), or testicular sperm extraction (TESA/TESE) where testicular sperm has lower fragmentation.
When: poor embryo quality or early embryo arrest in lab
APS panel (lupus anticoagulant, anticardiolipin, anti-β2GP1), Factor V Leiden, prothrombin mutation, protein C/S, antithrombin, homocysteine. Guides heparin + aspirin use from transfer day in positive cases.
When: especially with prior miscarriage or recurrent implantation failure
Peripheral blood NK cell count and activity, or endometrial NK cell biopsy. Elevated activity may indicate immune rejection of embryos. Treated with prednisolone, intralipid infusions, or hydroxychloroquine. Done when standard causes have all been excluded.
When: unexplained RIF after hysteroscopy, ERA, PGT-A all done
3D ultrasound detects uterine morphology issues (arcuate, bicornuate uterus) and endometrial pattern. Doppler assesses uterine artery blood flow — poor flow is associated with thin endometrium and implantation failure. Guides uterine vasodilator treatment.
When: thin endometrium or poor endometrial pattern on previous cycles
Detailed review of all previous cycle records: stimulation protocol, peak oestradiol, progesterone on trigger day, number of eggs, fertilisation rate, embryo grading days 1–5, transfer day, endometrial thickness and pattern. Identifies optimisation opportunities missed in previous cycles.
When: always — before designing next protocol
In a standard FET cycle, embryos are transferred at a fixed time — assumed to be when the endometrium is receptive. But 30% of women have a displaced window — their endometrium is receptive earlier or later than the standard protocol assumes.
The ERA test takes a biopsy of your uterine lining at the standard transfer time and analyses the expression of 248 genes linked to receptivity. The result is: "Receptive" (transfer as normal), "Pre-receptive" (transfer later), or "Post-receptive" (transfer earlier).
The next FET is then timed to your personalised window — with implantation rates significantly higher in ERA-guided transfers for women who had a displaced window.
Each cause has a specific, evidence-based treatment — not the same protocol repeated
Biopsy and chromosome test every blastocyst embryo. Transfer only euploid (normal) embryos. Reduces "wasted" transfers of genetically abnormal embryos. Single biggest protocol change for women over 35 with multiple failures.
↑ Implantation rate: 60–70% per euploid embryo transferred
Polyp removal, fibroid resection, adhesion division, septum resection — all done in the same hysteroscopy procedure. 4–8 weeks healing before FET. Implantation rates return to expected levels after cavity normalisation.
↑ Success rate: 2× improvement after cavity correction
Progesterone exposure is adjusted based on your ERA result. Transfer is scheduled at your personalised receptive window — hours earlier or later than standard. One ERA test guides all future FET cycles (window is stable).
↑ Implantation in displaced-window patients: significantly improved
Laparoscopic removal of the affected tube eliminates toxic fluid leakage into the uterus. IVF success rates return to expected levels for your age group. Done 4–6 weeks before next IVF cycle. Proximal ligation is an alternative if salpingectomy is not possible.
↑ From 50% below expected → back to normal success rate
IMSI uses 6000× magnification (vs 200× standard ICSI) to select sperm with minimal vacuoles — a marker of DNA integrity. TESA (testicular sperm aspiration) harvests sperm directly from the testis — testicular sperm has significantly lower DNA fragmentation than ejaculated sperm.
↑ Embryo quality and development rates with lower-SDF sperm
Low-dose prednisolone (5–10 mg/day) from embryo transfer. Intralipid (intravenous lipid infusion) once or twice per cycle to dampen NK cell activity. Hydroxychloroquine for longer-term immune modulation. Used only when standard causes are excluded.
Improving evidence in unexplained RIF with elevated NK cells
Low-molecular-weight heparin injections started from the day of embryo transfer — prevents microscopic clotting around the implanting embryo. Low-dose aspirin improves uterine blood flow. Continued through first trimester if pregnancy is confirmed.
↑ Implantation and early pregnancy maintenance in APS/thrombophilia
Extended oestrogen (oral + vaginal + patches), vaginal sildenafil (improves uterine artery flow), low-dose aspirin, G-CSF uterine infusion, or Platelet-Rich Plasma (PRP) injection into the uterine cavity — builds lining before FET. Transfer only when lining reaches ≥8 mm with trilaminar pattern.

Good-looking embryos failing to implant is called Recurrent Implantation Failure (RIF). The most common reasons are chromosomal abnormalities in embryos that appear visually normal (PGT-A is needed), uterine cavity issues invisible on 2D scan but seen on hysteroscopy, a displaced implantation window (ERA test), sperm DNA damage causing poor development after fertilisation, or immune/clotting factors. A systematic investigation at Mother Hospitals identifies the cause in most cases and guides a fundamentally different next cycle.

The ERA (Endometrial Receptivity Analysis) test analyses 248 genes in your uterine lining to determine whether your implantation window is on time, early, or late. In 30% of women with repeated implantation failure, the window is displaced — meaning embryos are transferred when the endometrium is not truly receptive. The ERA gives a personalised transfer schedule. It is recommended after 2–3 failed FET cycles with good quality embryos where the cavity is confirmed clear on hysteroscopy.
Sperm DNA fragmentation (SDF) is damage to the genetic material inside sperm. A normal semen analysis does NOT rule this out — count, motility, and morphology can all be normal while DNA is significantly fragmented. High SDF causes fertilisation and early cell division but then embryos arrest or develop poorly. If your embryos consistently fail to reach blastocyst (Day 5) or are poor quality despite good eggs, SDF is a key suspect. A DFI test costs ₹3,000–5,000 and can be done before the next cycle.
Yes — dramatically. A fluid-filled blocked tube continuously leaks toxic fluid into the uterine cavity, reducing IVF implantation rates by approximately 50%. Critically, it can be missed on routine 2D ultrasound — a careful 3D scan or hysteroscopy is needed. Salpingectomy (laparoscopic removal of the tube) before the next IVF cycle fully corrects this and restores expected success rates. This is one of the most impactful and overlooked causes of repeated IVF failure.
Donor eggs are considered when poor egg quality is confirmed as the cause — indicated by: consistently poor fertilisation rates, all embryos arresting before Day 5, very low AMH with poor response despite optimised protocols, or age over 42–43 with repeated failures. However, before considering donor eggs, PGT-A should confirm that embryos are chromosomally abnormal (not just morphologically poor), and the uterine environment should be optimised. If PGT-A shows normal embryos are failing to implant, the problem is the uterus — not the eggs — and donor eggs will not help.
A second opinion should be sought after two failed cycles — especially if no investigation into the cause has been performed. After one failure, changing is premature — IVF has a 40–50% success rate per cycle even optimally, and one failure can be a chromosomal random event. After two failures without investigation, the pattern needs analysis. If your clinic is repeating the same protocol without investigating why it failed, that is a clear signal to seek an external review. Bring your complete records to Mother Hospitals — a detailed protocol review is done at every second opinion consultation.
Standard ICSI selects sperm at 200–400× magnification. IMSI (Intracytoplasmic Morphologically Selected Sperm Injection) uses 6000× digital magnification — revealing fine structural details of the sperm head, including vacuoles that indicate DNA damage. Sperm with vacuoles are excluded; only the most structurally perfect sperm are selected. IMSI is recommended when sperm DNA fragmentation is high or when previous ICSI cycles have produced poor embryo quality. It is available at Mother Hospitals as part of the RIF investigation protocol.
Yes — and this is one of the most common scenarios we see. Bring your complete records from previous cycles (stimulation protocol, laboratory reports, embryo grading, transfer records, all investigation results). Dr. Prashanthi reviews these in detail, identifies what may have been suboptimal, and designs a protocol specifically for your case. You do not need to repeat baseline investigations that were recently done elsewhere — we build on what has already been established.
