New Breath Test to Help Increase Pregnancy Rates

A new breath test has launched that can help to increase pregnancy rates with the world’s first fertility tracker breathe ilo, that uses breath analysis (CO2) to identify ovulation patterns.

With a study revealing that only 12.7% of women correctly estimate their ovulation day¹, breathe ilo is the easiest and most comfortable way to naturally track cycles with a small handheld device that is synced to an app. The technology reads the breath’s CO2 saturation to determine where a woman is in her cycle with incredible accuracy. The device uses real-time ovulation and historic symptom data to offer women precise day-to-day insights into their fertility forecast. 

The new technology signals a shift so women no longer need to track their cycles by urinating on a stick or by measuring their temperature early in the morning. The innovative device works by simply breathing and displays the results in just 60 seconds, with no consumables or maintenance needed. Through consistent daily use, the breath analysis tracker empowers women to understand their body and cycle phases better. 

The breathe ilo app, which is compatible with iOS and Android, features a calendar that displays a clear overview of fertile days and a cycle diary to learn more about individual cycle patterns. breathe ilo’s cycle diary also offers the possibility to document further cycle symptoms like breast tenderness, PMS, cervical mucus, or headaches to help prepare women for their next cycle. 

Lisa Krapinger, breathe ilo’s spokesperson, says, “We believe that fertility and cycle tracking should not be a tiresome task. breathe ilo is designed to bring fertility tracking into the 21st century and the precise and uncomplicated nature of the device is the future of female health by using their breath.

Our mission is to not only make fertility tracking as easy as breathing, but we have a wider ambition to create a comfortable space where women can speak freely about trying to conceive and their menstrual cycles, along with all that is in between. With 640,370 women in England & Wales giving birth in 2019², we hope to make it easier and less stressful for those trying to conceive moving forward.”

With the option to buy a device for £259.00 or rent for £29.90 a month, breathe ilo is available to purchase exclusively now at
