It’s not the first fertility app out there, but Berglund’s app works so well that it’s been shown to help women avoid pregnancy with 99.5 percent reliability – to put that into perspective, condoms are 98 percent effective, and IUD devices are 99 percent reliable, as is the pill, when taken at the same time every day.
Best of all, the app doesn’t have any side effects, and just requires women to input their temperature daily to map their fertility throughout the month. . . .
Using a woman’s natural fertility cycle to help her avoid getting pregnant isn’t a new idea –
but Berglund’s algorithm is different – it uses the same advanced statistical methods she used at CERN, and is based on a woman’s daily temperature rather than simply the day of her cycle. That’s because after ovulation, women see a spike in progesterone, which makes their bodies up to 0.45 degrees Celsius warmer. So by entering your temperature in the app daily, and comparing the results with a broader dataset, the app lets you know when you can have unprotected sex (a green day) and when to use contraception, such as condoms (a red day).
There have been two trials so far, and the second one analysed data on more than 4,000 women aged 20 to 35 using the app.
