Dr. Natalie Crawford, MD, is a double board-certified OB-GYN and reproductive endocrinologist. We discuss how to improve hormone health at any age and the importance of fertility markers not just for pregnancy, but as a powerful window into overall health, vitality and longevity. We discuss hormone replacement therapy, egg freezing, IVF, and what biomarkers like AMH really indicate. Plus, how anti-inflammatory diets and specific supplements can be beneficial and the impact of microplastics and certain fragrances on hormones. We also discuss lesser-known factors that deplete male and female fertility, vitality and health. This conversation highlights how better understanding of hormones and your reproductive markers can empower better informed choices at every stage of life. Read the show notes at hubermanlab.com.
