The Egg Factor Podcast: Day 3 vs. Day 5 Embryo Transfers

The episode is also available on Spotify and Apple Podcasts!

In this episode of The Egg Factor, CHR’s Medical Director, Dr. Norbert Gleicher, unpacks one of the most commonly debated topics in IVF: Day 3 vs. Day 5 embryo transfers. Should embryos be transferred earlier or later—and what does the latest science actually say about success rates, implantation potential, and long-term outcomes?

Dr. Gleicher challenges prevailing assumptions in fertility care, discusses CHR’s individualized approach, and explains why extending embryos to blastocyst stage may not always be the best strategy—especially for patients with low ovarian reserve.

Whether you're early in your IVF journey or revisiting your treatment plan, this episode offers evidence-based insight you won’t hear everywhere else.
