Inside the Lab: The Science Behind Your Embryos
Special Guest: Olivia Pavlik, Embryology Lab Manager
What actually happens to your eggs, sperm, and embryos once they disappear behind the lab doors? 👀
In this episode, Laura and Brandis sit down with Olivia Pavlik, CNY Fertility’s Embryology Lab Manager, for a deep (but approachable) dive inside the IVF lab — answering the questions patients ask all the time but rarely get explained in plain English.
From fertilization methods to embryo grading, PGT testing myths to why embryologists work holidays, this episode pulls back the curtain on the science, precision, and heart behind embryology.
🧬 What We Cover in This Episode
✨ Meet the Embryologist:
Olivia shares her journey into embryology — including the full-circle moment of being an IUI baby herself and now helping others build families.
🔬 ICSI vs. Conventional IVF – What’s the Real Difference?
Why CNY uses ICSI for nearly all IVF cycles, the risks of conventional fertilization, and why ICSI isn’t “less natural” than people think.
🧪 Zymōt, PICSI & DNA Fragmentation
What sperm-selection add-ons actually do, which ones show benefit, and why Zymōt may be a smarter option than expensive DNA fragmentation testing for some patients.
⚡ Calcium Ionophore: When Is It Used?
Why this add-on is reserved for specific cases like failed fertilization — and why more isn’t always better.
📊 Embryo Grading (A Real-Talk Breakdown)
What embryo grades actually mean, why they’re subjective, and why lower-graded embryos can still become healthy babies.
🧠 PGT Testing, Mosaicism & Misconceptions
What’s tested, what’s debated, why mosaic embryos can still work, and why genetics matter more than looks.
🧯 Assisted Hatching & Embryo Glue
What they are, when they’re used, and how embryologists help embryos implant without harming them.
🧾 Embryo Safety & Witnessing Protocols
How CNY ensures the right embryo goes to the right patient — with multiple layers of human verification and redundancy.
❤️ The Human Side of the Lab
Why embryologists work weekends, holidays, blizzards, and hurricanes — and how deeply they understand the weight of their work.
🧊 What Happens to Unused Embryos?
A compassionate, honest discussion about embryo storage, donation, training, research, and disposal — and why there is no “dumpster full of embryos.”
💬 Key Takeaways• Embryo grading is a prioritization tool, not a prediction
• “Pretty” embryos don’t guarantee pregnancy — genetics matter most
• Not all add-ons are equal (and some are just trendy 👀)
• Embryologists treat your embryos with the same care they’d want for their own
• Knowledge = power when navigating IVF decisions
If you’ve ever wished you could just talk to the lab, this episode is for you.
