Brought to you by Penguin.

An indispensable guide to fertility, covering everything you need to know to optimise your hormones, get pregnant and take charge of your reproductive health.

Most of us are taught there’s nothing we can do to improve our fertility – that it’s simply a matter of luck – but this couldn’t be more wrong. In The Fertility Formula, fertility expert Dr Natalie Crawford breaks down the science behind fertility and guides you through what you can do, starting now, to improve your fertility and your chances of getting pregnant.

Weaving together cutting-edge science, clinical insight and patient stories, Dr Crawford gives you the tools to take control of your reproductive health, including:

• The most common but overlooked causes of infertility – and what you can actually do about them
• The truth about the ‘biological clock’, and why egg quality is about more than just age
• How to accurately track your menstrual cycle for conception, pregnancy prevention, and hormone health – 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 and movement
• 20+ recipes for quick, easy, and delicious meals that support hormones and fertility

It’s time to put fertility back in your hands – and The Fertility Formula will give you the knowledge, tools, and confidence to look after your reproductive future.
