🎧 Episode Overview:

In this solo episode of Modern Thyroid Wellness, McCall McPherson, thyroid expert and founder of Modern Thyroid Clinic, explores the critical connection between thyroid health and fertility. Even mild or subclinical thyroid dysfunction can have profound effects on conception, pregnancy outcomes, and postpartum recovery—yet it's often overlooked in conventional care.

She offers actionable guidance on how to advocate for more comprehensive testing and personalized hormone management before, during, and after pregnancy.
