In this episode of the Good Medicine Podcast, Dr. David Bearss sits down with Dr. Jim Hotaling and Dr. Brad Cairns from Paterna Biosciences to talk about a new way of thinking about male infertility.
Dr. Brad Cairns explains that in many cases, stem cells themselves are not the root of the problem. Instead, the issue lies in the supporting or chaperoning cells that guide stem cells through normal development. Paterna’s work focuses on restoring that developmental process rather than replacing cells outright.
The conversation also explores how Paterna is developing approaches to help men with infertility at many different stages, offering options even when traditional treatments have failed. Dr. Jim Hotaling shares the deeply personal side of this work, reflecting on his role in delivering life altering news to families and how that responsibility drives his commitment to building better solutions.
This episode blends cutting edge science with the human reality behind infertility and why progress in this space matters so much.
