What Does It Really Mean When Ovaries Age?

We often hear about the biological clock—but what does “ovarian aging” really mean? In this episode of The Egg Factor, Dr. Norbert Gleicher and Dr. David Barad explain the science behind ovarian aging, how it differs from chronological age, and what it means for fertility—especially for women in their late 30s, 40s, or those diagnosed with low ovarian reserve.

Brought to you by the Center for Human Reproduction (CHR) on the Upper East Side of New York City. With over 40 years of experience and a history of innovation, CHR has been at the forefront of fertility care since the beginning.

Our founder, Dr. Norbert Gleicher, reported the first successful transvaginal egg retrieval in human history, helping to shape the future of IVF as we know it today. CHR is known for tackling some of the most challenging fertility cases—especially women over 40 and those with diminished ovarian reserve—by offering highly individualized, evidence-based care when others often turn patients away.
