The Physicists Who Found The Higgs Boson Now Build Birth Control

Natural Cycles just hit a significant regulatory milestone with its sixth FDA clearance. The company, which pioneered the first FDA-cleared birth control app, is using a next-generation algorithm to process massive amounts of fertility data. What stands out is the team behind the technology. Several leaders at the company, including co-founder Elina Berglund Scherwitzl, are former particle physicists who worked on the discovery of the Higgs boson at CERN.

This transition from high-energy physics to reproductive health is not a coincidence. These researchers approached fertility tracking as a data problem. While medical practitioners focus on clinical observations, these scientists applied the same statistical rigor used in particle physics to isolate genuine physiological signals from noise. By processing data on previous cycles and hormonal trends, they developed a tool that distinguishes ovulation patterns with high precision.

This approach challenged traditional medical views on women's health. For years, complex hormonal fluctuations were often dismissed as too variable for accurate measurement. These physicists treated that complexity as a dataset to be interrogated. They spent years securing regulatory approvals, eventually moving the product from a niche wellness tool to a Class II medical device that offers 98 percent effectiveness with perfect use.

To move from a theoretical algorithm to a practical tool, the company integrated clinical expertise into their development. Physicians like Dr. Kerry Krauss and Dr. Semiya Aziz provide the necessary medical context, bridging the gap between raw data and patient care. Dr. Aziz notes that menstrual cycles act as vital signs, often offering early indicators of broader health trends. By shifting the power of data collection into the hands of women, the company is changing the dynamic between patients and providers.

As the industry explores new technologies, such as continuous hormone monitoring, Natural Cycles continues to emphasize peer-reviewed evidence. Their latest clearance rests on their thirtieth published study. This trajectory shows how disciplined data practices can meet the standards of regulated medical devices. Women now have access to tools that turn personal health information into actionable insights, moving them from passive recipients of care to active participants in their health decisions.
