Fertility may be more about the daily choices we make rather than factors like delayed maternal age, says fertility physician Dr. Natalie Crawford. Markers of metabolic health, such as chronic inflammation, affect women’s egg quality. Crawford, who experienced four failed pregnancies before having her children, began studying the link between inflammation and infertility. Taking charge of your fertility, she says, means having early conversations about hormonal health and taking steps, like better sleep and nutrition, to improve your chances of getting pregnant. She speaks with Pamela Brown, anchor and correspondent for CNN, about her new book The Fertility Formula: Take Control of Your Reproductive Future.
