Natural Cycles FDA Clearance Advances Its Next-Generation Fertility Algorithm
Natural Cycles FDA clearance news is pushing digital contraception into its next chapter. Natural Cycles announced that it has received its sixth FDA clearance, this time for a next-generation AI-powered fertility algorithm designed to make fertility predictions more personalized while maintaining the app’s established effectiveness rates.
The announcement, published through PR Newswire, says the clearance covers the company’s updated NC Fertility Algorithm. The algorithm combines statistical modeling with machine learning trained on tens of millions of real-world fertility data points.
Natural Cycles describes the update as a way to give many users more Green Days, or days when the app confirms pregnancy protection is not needed, while maintaining its established safety and effectiveness. According to the release, Natural Cycles remains 98% effective when used as intended and 93% effective with typical use.
Why Breath3in is watching this
This belongs in the Breath3in press release feed because it sits at the intersection of women’s health, regulated software, biomarker tracking, wearable data, and everyday behavior. It is not just an app update. It is a signal about where reproductive health tools are going.
For a long time, cycle tracking sat in a softer wellness category. Natural Cycles is part of a more serious shift: software that touches daily routines, intimate health decisions, medical-device regulation, and personal data all at once. That is the bigger thing to watch.
There is also a cultural layer here. More people are asking for health tools that feel less blunt and more personalized. That does not make the technology simple. It actually raises the standard. If a product is going to guide birth control decisions, the science, data privacy, regulatory review, and user education all matter.
What the updated algorithm does
According to the release, the updated algorithm is designed to provide more Green Days while maintaining effectiveness, improve performance for people with irregular cycles, better handle lower-quality temperature and biomarker data, and personalize more quickly as cycles change over time.
The company also said it has filed a patent application covering key innovations in the updated algorithm. Natural Cycles frames the clearance as part of a longer regulatory path for digital contraception, including FDA clearances for integrations with Oura Ring and Apple Watch, over-the-counter and prescription availability, and a regulatory pathway for future hardware integrations.
Company context
Natural Cycles is a women’s digital health company founded in 2013 by physicists Dr. Elina Berglund Scherwitzl and Dr. Raoul Scherwitzl. The company developed an FDA-cleared digital method of birth control powered by an algorithm that interprets biomarker data, including body temperature, to provide personalized cycle insights and daily fertility status.
The Natural Cycles app includes modes for birth control, planning pregnancy, following pregnancy, postpartum, and perimenopause. The company says it has more than six million registered users worldwide and 30 peer-reviewed studies.
