NaturalCycles was founded by husband and wife, Elina Berglund and Raoul Scherwitzl out of a personal need. With PhD’s in physics, they applied their mathematical techniques to developing the NaturalCycles algorithm in order to find a healthy way to prevent and plan pregnancy. Elina was a researcher at CERN and was one of the physicists that discovered the Higgs Boson, which lead to the Nobel Prize in 2013. The clinical study proving NaturalCycles 99.9% accuracy is soon-to-be published in the peer-reviewed European Journal of Contraception and Reproductive Health.
