The Fertility Formula
Fertility is more than luck—it’s science. And it starts long before you’re ready to conceive.
In this groundbreaking new book, board-certified Reproductive Endocrinologist and host of the As a Woman podcast, Dr. Natalie Crawford, pushes back on the standard recommendation requiring women to fail before we learn about our fertility. As infertility rates are rising, it is essential that we approach fertility proactively and begin to learn more about trimester zero.
The Fertility Formula is a science-backed, compassionate guide that reveals the connection between inflammation and fertility, empowering women to understand their hormones, optimize their health, and take charge of their fertility. Whether you're thinking about future family planning or simply want to feel better in your body today, this book is your essential starting point.

The guide to fertility, hormones, and lifestyle
Most of us are taught there’s nothing we can do to improve our fertility. It’s simply a matter of luck—and some of us are luckier than others. But this couldn’t be more wrong. When it comes to your health, hormones, and fertility—you deserve to be the one in control of your future.
An indispensable guide to fertility, covering everything you need to know to optimize your hormones, get pregnant, and take charge of your reproductive health.
This book will do what the other hormone and fertility books on the market have failed to do: teach you what you need to know about your lifestyle so you can optimize your hormones, health, and fertility now.
In The Fertility Formula, fertility physician Dr. Natalie Crawford reveals the science behind fertility and what you can do, starting now, to improve your fertility and your chances of getting pregnant.
It turns out, most root causes of infertility—from hormone issues and endocrine diseases like PCOS to abnormal cycles and endometriosis, even age-related factors—can be traced back to one thing: inflammation. Understanding and addressing this inflammation is the key to optimizing your fertility at every level.
Whether you're trying to conceive now, in the depths of infertility, or simply want to support your hormone health, this book gives you the knowledge and tools you need to take control.
In The Fertility Formula, you’ll find:
How fertility is a health marker for current and future disease
Why your fertility matters now even if you are not ready to get pregnant
The science behind how inflammation hijacks your fertility
The truth about the biologic clock and why egg quality is about more than just age
How to accurately track your menstrual cycle and uncover the root cause of abnormal cycles
A step-by-step guide to getting pregnant, from timing intercourse with ovulation to navigating infertility treatments if needed
A lifestyle plan to improve your hormone health, reduce inflammation, and boost fertility—through better sleep, stress-reduction, nutrition, movement and decreasing toxins
20+ recipes for quick, easy, and delicious meals that support hormones and fertility
Praise for The Fertility Formula
“Fertility isn’t luck. It’s knowledge, awareness, and empowerment. In The Fertility Formula, double board–certified OB-GYN and reproductive endocrinologist Dr. Natalie Crawford breaks down what every woman should know about her hormones, cycle, and reproductive health but was never taught. Grounded in science and empathy, this book gives you the tools to understand your body, protect your fertility, and take control of your future.”
Dr. Mary Claire Haver, board certified OB-GYN and bestselling author of The New Menopause
“Dr. Natalie Crawford has written the book I wish every woman had from the very beginning of her reproductive life. The Fertility Formula is not just about getting pregnant—it’s about understanding your body, your hormones, your health, and your options. She hands us the agency we have always deserved, guiding us toward a future where we can make informed choices for ourselves. This book is power. This book is permission. This book is a lifeline for women who are ready to take control of their own story.”
Jen Hatmaker 5x NY Times bestselling author and host of the For the Love Podcast
"For any woman wanting to conceive, The Fertility Formula has the insights to help unlayer the complexities, the fears, and gives actionable insight and hope. Dr Natalie Crawford shines as an expert clinician, but with the human softness to unpack the confusion and create clarity for all. I highly recommend this book to the many women (and their partners) who are seeking answers and guidance from a true, compassionate expert."
Stacy T. Sims, PhD, author of Roar and Next Level
“In The Fertility Formula, Dr. Natalie Crawford MD makes it clear how to assess and optimize your reproductive and hormone health. The roadmap she provides is based on her extensive clinical experience with thousands of patients, each of whom arrived to her with different histories, hopes and needs. The Fertility Formula is not only crucial for those who are planning to have children, it should be read by every woman-- regardless of age or reproductive goals, because of the close relationship that exists between hormone and general health, especially in women. The Fertility Formula is going to vastly improve and indeed save countless lives, and surely create many new ones as well!”
Dr. Andrew Huberman, Ph.D., Stanford School of Medicine & Host of the Huberman Lab Podcast
“I am so excited to be able to refer my readers to The Fertility Formula by Dr. Crawford . It’s such an accessible guide, not just for those dealing with fertility issues, but those wanting to be proactive with their family-building. By using a wholistic approach to diagnosing the root cause of a problem, she covers the overall health of both women and their partners, including evidence-based recommendations about nutrition and other complementary therapies that really should be part of any excellent clinician’s therapeutic options. I also love her use of analogies to explain complicated principles. And the fact that she was so honest about her own fertility challenges makes her that much more credible and sensitive to the concerns of her readers and patients. Kudos for a fabulous book!”
Toni Weschler, MPH, Author of Taking Charge of Your Fertility and co-creator of the cycle tracking app, Cyclisity
As a surgeon and longevity doctor, I’ve long believed that our menstrual cycle is not a mystery to be endured but a vital sign—one of the clearest indicators of our metabolic health, hormonal balance, and overall well-being. In The Fertility Formula, Dr. Natalie Crawford demystifies this truth with science-backed clarity, compassion, and deeply practical steps that every woman deserves to know. Her evidence-based approach to optimizing reproductive health fills a gap that has existed for far too long, and I can honestly say I would have loved to have a book like this when I was hoping to have children. Dr. Crawford has created a truly empowering guide that helps women understand their bodies and take confident action in one of the most important aspects of their health.
Vonda Wright MD, MS, board certified orthopedic surgeon and New York Times best selling author of Unbreakable
“The Fertility Formula makes a powerful case for a proactive, anti-inflammatory approach to fertility -- and to health itself. Dr. Natalie Crawford shows how healing the gut, calming inflammation, and syncing your rhythm can help you take control of your reproductive future. A bold and necessary roadmap for thriving reproductive health and overall well-being.”
Will Bulsiewicz, MD, MSCI, Gastroenterologist and New York Times bestselling author of Plant Powered Plus
“Natalie Crawford, MD, has written the book I wish every patient—and every clinician—had years ago. The Fertility Formula is honest, practical, and deeply empowering, giving readers the knowledge and confidence they need to understand their bodies and advocate for their fertility with clarity and compassion. The Fertility Formula provides a fertility roadmap that is both an actionable checklist and a deeply evidence-based guide. She helps readers understand the ‘why’ behind every recommendation, helping women truly understand—and take control of—their fertility.”
Lora Shahine, MD, board certified OB-GYN and reproductive endocrinologist, author, host of the Brave and Curious podcast
“Women are taught to treat fertility like a coin toss — something you get lucky with or not. In The Fertility Formula, Dr. Natalie Crawford makes clear just how culturally harmful this thinking is. Crawford gives women the language and agency to approach their fertility with care and control — Amen to that!”
Dr. Pooja Lakshmin MD, psychiatrist and author of Real Self-Care
The Fertility Formula goes far beyond getting pregnant—it teaches you to understand your body so deeply no one can dismiss your experience again. With expert clarity and genuine allyship, Dr. Crawford breaks down hormones, cycles, and reproductive health in a way every woman deserves. If you’ve ever felt dismissed or told to “just relax,” this practical and empowering guide is your antidote to confusion, shame, and silence.
Dr. Kelly Casperson, board certified urologist and author of The Menopause Moment
"A comprehensive guide to the science behind hormones and conception, including the role of lifestyle factors such as nutrition, exercise, and sleep. An absolute must-read for anyone looking to understand and optimize their fertility!"
Karen Tang, MD, board certified gynecologist and author of It's Not Hysteria: Everything You Need to Know About Your Reproductive Health (but Were Never Told)

Hi friends! I’m DR Natalie CRAWFORD -
I’m a double board certified fertility doctor with a nutrition degree who loves science.
I am passionate about optimizing your lifestyle to improve your fertility. I love educating you about your body and fertility.
I’m also a mom to 2 who struggled with infertility and pregnancy loss. My kids were pregnancies 5 & 6 after four pregnancy losses. During my own infertility, I searched everywhere for educational content that could help guide me on what I could do to improve my chances of conceiving. I researched natural fertility and lifestyle factors in fellowship and beyond—and kept seeing one word over and over: inflammation. What started with Instagram has grown to include the As a Woman Podcast and my YouTube channel—Natalie Crawford, MD.
I am co-founder of Fora Fertility, a boutique fertility practice in Austin, Texas, and Pinnacle Conference, a leadership conference for women in medicine. You’ll also find me speaking to national media outlets about fertility, IVF, and hot news topics. I am a huge believer that you can’t make decisions on data you don’t know.
The Fertility Formula represents years of dedication, passion, and hard work to help you get information you can trust about fertility, hormones and lifestyle. I’m so thrilled to finally share this book with you.
