Why do eggs that look perfect on retrieval day sometimes lead to poor embryos, failed implantation, or no pregnancy at all?
If your clinic once told you your eggs “look great,” only to later say the cycle failed due to an egg issue… you’re not alone. And no, your doctor didn’t lie to you.

In this episode of Taco Bout Fertility Tuesday, Dr. Mark Amols unpacks one of the biggest misunderstandings in IVF:
the difference between how an egg looks and how an egg functions.

Drawing from real-world experiences and the new research review “Unveiling the Realms of Reproduction: A Reflection of Oocyte Assessment” by Gardner et al. , Dr. Amols breaks down:

• Why egg morphology (appearance) is a terrible predictor of success
• What embryologists can see… and what’s completely invisible
• Why the true egg issues only show up later — during fertilization, cleavage, and blastocyst development
• The “cohort effect”: why some cycles are full of rock-star eggs and others feel like the B-team
• Why a failed cycle doesn’t mean your eggs are bad or that you did anything wrong
• The future of egg assessment: AI scoring, time-lapse imaging, metabolomics, autofluorescence, and more

If you’ve ever wondered how “good eggs go bad,” or felt frustrated when early optimism turned into confusion, this episode gives you the clarity, science, and reassurance you’ve been looking for.
