  • CERN Physicist’s Fertility Algorithm Prevents Unwanted Pregnancy With 99.5% Efficacy

    A CERN physicist’s algorithm has been used to both prevent unwanted pregnancies and help over 5,000 women conceive.
    The creators hope for the app to officially be categorized as a contraceptive device.
    A NEW TRACK

    Back in 2012, a team at the Large Hadron Collider (LHC) found the elusive Higgs-Boson particle. While an impressive feat, it does raise the question: how do you top a discovery like that?

    For one physicist, the answer was to expand her horizons. That’s right, a scientist who was a part of the discovery of the Higgs-Boson switched gears to the field of female fertility, and has created an app that could eventually be the first smartphone-based contraceptive.

    The fertility app is called Natural Cycles, and it was developed by physicist Elina Berglund when she noticed there were few natural options for birth control. She even began the work while still at CERN.

    In order to provide a solution for this problem, she wrote an algorithm that analyses the user’s body temperature (input into the app) to display fertile and infertile days. Unlike other applications, Berglund’s algorithm is based on advanced statistical methods, earning it the distinction of being the only app of its kind regulated as an approved medical device.

    • Can an algorithm replace the pill? Natural Cycles app wants to do just that

      Berglund’s algorithm - based on advanced statistical methods from her time at CERN - uses body temperature to determine fertility. After ovulation, increased levels of progesterone make women’s bodies up to 0.45°C warmer. Input your daily temperature into her app, and by comparing the readings with those in its data set, it lets you know when you can have unprotected sex (shown as a green day in its calendar) and when to use contraception (shown as red).

      Natural Cycles has conducted two clinical trials, the second of which analysed the data of more than 4,000 women aged 20-35. Over the course of one year, there were 143 unplanned pregnancies, ten of which occurred on green days, giving the app a 99.5 per cent efficacy rating - the same as the pill. Natural Cycles is currently the only app of its kind to be regulated as an approved medical device, putting it in the same category as condoms and IUDs - albeit in a different class.
