Disrupts UK’s £320M fertility sector with breath analysis technology


Austrian femtech start-up breathe ilo, today lands on UK shores with the first-ever fertility breath test to help increase pregnancy rates in the UK, with a £4.4M investment. The innovative handheld device uses breath analysis to track fertility and menstrual cycles by measuring the breathe’s CO2 saturation levels – a first in the UK and world.


With the UK fertility sector estimated to be worth £320M, women can correctly estimate their ovulation day with breathe ilo, which offers an easy and comfortable way to naturally track cycles with incredible accuracy.


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 that connects to the app, 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 brainchild of leading gynaecologist Professor Dr. Ludwig Wildt and Dr. Horst Rüther, the parent company of breathe ilo, Carbomed Medical Solutions GmbH was founded in 2013. Following successfully launches in Austria and Germany in May 2019 and with a 15% month-on-month growth, breathe ilo’s inception has helped 1 in 3 women fall pregnant in just three months.
