Together, they break down:

- The science behind mitochondrial transfer
- Why this technique is currently banned by the FDA

While headlines might portray it as a breakthrough, CHR’s team sees it differently. Tune in for a grounded, science-based conversation about why this experimental method isn't the solution it's being marketed to be—and what real innovation in fertility care should look like.

In this listener-driven Q&A episode of The Egg Factor, CHR’s Dr. Norbert Gleicher and Dr. David Barad answer two critical questions from our patient community. First up: If you're doing a Day 3 frozen embryo transfer (FET) and had no choice—should you opt for a medicated or modified natural cycle? Then, the doctors tackle a question that weighs heavily on many: What are the most common chromosomal abnormalities seen in women 40 and older, and how do they impact fertility treatment?

Known for their candor and decades of clinical experience, Dr. Gleicher and Dr. Barad break down the science behind these decisions and offer guidance for navigating the complex path to parenthood later in life.
