Bad IVF News? What to Do Next - From the Lab’s Perspective

Hearing disappointing IVF results can be devastating, but understanding the laboratory findings can help you make informed decisions about your next steps. Here's what embryologists wish patients knew when facing challenging outcomes.

Decoding Common Scenarios and Lab Insights

1. "No Embryos Made It to Blastocyst"

What the lab sees:

  • Arrest at cleavage stage (Days 2-3)

  • Failure to compact (Day 4)

  • Early blastocyst collapse (Day 5)

Possible causes:

  • Chromosomal abnormalities (60-80% of cases)

  • Sperm DNA fragmentation

  • Mitochondrial dysfunction

  • Suboptimal culture conditions

Lab-recommended next steps:

  • Request detailed embryo development notes

  • Consider PGT-A testing in future cycles

  • Discuss culture media alternatives

  • Evaluate sperm DNA fragmentation testing

2. "All Embryos Were Poor Quality"

Grading reality check:

  • CC-graded (3CC, 4CC, etc.) blastocysts have <15% implantation rate

  • Severe fragmentation (>25%) reduces viability

  • Asymmetric cell division impacts the potential

Lab perspective:

  • "Poor quality" often reflects chromosomal issues

  • Some "ugly" embryos can still be genetically normal

  • Morphology doesn't always predict function

Action items:

  • Review time-lapse videos if available

  • Ask about rescue ICSI for future cycles

  • Consider co-culture systems if repeated

3. "Fertilization Failed"

Behind the lab door:

  • 0PN (no pronuclei) vs 1PN (one pronucleus) outcomes

  • Post-ICSI degeneration rates

  • Sperm binding/activation issues

Technical solutions:

  • Calcium ionophore activation (for egg activation deficiency)

  • PICSI sperm selection (for binding issues)

  • Polarized light microscopy for spindle detection

The Lab's Problem-Solving Toolkit

There are a few things the lab can do. We’ve included a graphic below, but keep in mind that it’s very rare for labs to perform these diagnostic measures. It’s more realistic for labs to try these assessments:

  • Spindle-view analysis - Checks meiotic spindle integrity for optimal ICSI timing

    • Check out this study by Suji Kim (2024) that found spindle-view significantly improved blastocyst transfers

  • Different ICSI timing - Gives eggs more time to mature for optimal ICSI timing

  • Physiologic ICSI (PICSI) - Captures mature sperm for ICSI

  • Zymot - Captures high-quality sperm for ICSI

  • Zona drilling - Thin the zona pellucida for less aggressive ICSI manipulation

  • Calcium Ionophore - Activates the egg

When to Seek a Second Opinion (From a Lab Specialist)

Red flags worth investigating:

  • 50% embryo arrest rate in multiple cycles

  • Fertilization rates <30% with ICSI

  • Discrepancies between egg maturity and blastocyst rates

  • Unusually high degeneration post-thaw

The Silver Linings Labs Observe

  1. One good embryo is enough - Many success stories start with a single fair-quality blastocyst

    1. The IVF Kitchen believes in positivity, yet we understand how this process can wear down positivity throughout the IVF cycle. This phrase, “one good embryo is enough,” is quite common, and while it is true, many patients have had issues with the phrase. Understandably, if we all played the statistics game, then yes, more is better, but this simply isn’t the reality for most patients. For the amount of negative experiences with only having one good embryo, there is easily more positive experiences from patients who only had one good embryo, so stay strong and stay positive!

  2. Arrest reveals problems early - Better than repeated implantation failure

  3. Each cycle provides data - Even "failed" cycles guide better protocols

  4. Technology keeps advancing - Today's limitations may be solved tomorrow

Your 7-Point Action Plan

  1. Schedule a lab consult - Not just with your doctor, but with the lead embryologist

  2. Request raw data - Developmental timelines, photos, grading sheets

  3. Compare to lab averages - Ask how your results stack up to their typical outcomes

  4. Review media/incubators - Some patients respond better to certain systems

  5. Consider split trials - Test different protocols simultaneously

  6. Explore clinical trials - Experimental approaches for tough cases

  7. Preserve evidence - Request vitrification of arrested embryos for future analysis

Each individual's situation is unique so don’t get discouraged when reading through this perspective. Even the most difficult cases have been able to have a live birth with today’s scientific advances in the lab. Every failed IVF cycle is an opportunity to collect relevant data so that you may have a baby on the next IVF cycle. Some of our most successful patients had multiple poor cycles before we cracked their unique biological code. The IVF journey is not an easy one, but definitely the most rewarding one!
