Oura Ring Expands Into Women's Health and Olympics

Oura, a Finnish wearable company, has secured official partnerships with Team USA and Team Finland for the 2026 and LA28 Olympic and Paralympic Games. This announcement caps an 18-month push into women's reproductive health that started with basic cycle tracking and now includes an FDA-cleared birth control tool.

Oura announced the Team Finland partnership on February 23, 2026, after being named the Official Wearable of Team USA and LA28 on February 6. These partnerships show how Oura is moving beyond consumer wellness devices to work with elite athletes, using the same sensors that track reproductive health.

How Temperature Tracking Works for Cycle Prediction

Oura's reproductive health approach relies on a simple biological fact: your skin temperature rises slightly after you ovulate. The ring's built-in temperature sensors detect these shifts — typically 0.2 to 0.5 degrees Celsius — and track patterns over time. The app maps your cycle phases and predicts fertility windows based on these nightly readings.

To work well, the system needs consistent overnight data to establish your baseline and spot meaningful changes. That's why wearing the ring to bed matters.

Oura paired this cycle tracking with Natural Cycles, a birth control app cleared by the FDA. Oura Ring owners can try Natural Cycles free for 28 days. The two systems work together automatically: the ring tracks your overnight temperature, and every morning it syncs that data to Natural Cycles' algorithm, which is designed specifically for fertility tracking and contraception guidance. The combined system reports 93 percent effectiveness with typical use and 98 percent with perfect use.

The company also built features for people using hormonal birth control pills or implants, since those change bleeding patterns in ways natural cycles don't. Oura added a separate Menopause Insights section for midlife users and partnered with Twentyeight Health to let U.S. members connect with licensed doctors for birth control prescriptions directly through the app.

The Wider Femtech Market

Oura isn't alone in this space. Competitors like Femometer Smart Ring and Evie Ring use similar technology — sensors in a small wearable that track temperature, heart function, and sleep to spot reproductive patterns. All three approaches rely on the same basic principle of overnight temperature monitoring.

The broader pattern here is worth noting: we have seen this progression before in consumer health technology. A device or app starts with general wellness tracking, then gets tested in clinical studies, then eventually becomes integrated into the actual healthcare system with doctors and prescriptions involved. The continuous glucose monitor took a similar path — it began as a tracking tool for athletes and wellness enthusiasts, then gained FDA approval for medical use, and now often connects to telehealth platforms where patients can see their doctors. Oura appears to be following that same map.

Money, Hardware, and Growth

Oura raised $200 million in December 2024, valuing the company at $5.2 billion. The company then raised another $900 million in October 2025, led by the investment firm Fidelity. Dexcom, a major company in glucose monitoring, invested $75 million in the first round and announced a strategic partnership, hinting at possible integration of glucose tracking into Oura's system down the line.

On the hardware side, Oura released the Oura Ring 4 in October 2024 with improved sensors, followed by ceramic versions in new colors and multi-ring support with a redesigned charging case in October 2025. The company also acquired Veri, a metabolic health startup, in September 2024 to expand what it could measure and analyze.

The sales numbers reflect this momentum. By June 2024, Oura had sold 2.5 million rings. By September 2025, that had grown to over 5.5 million, and the company had doubled its revenue for the second year in a row.

AI Insights and Partnerships

In March 2025, Oura launched Oura Advisor, an AI system that gives personalized health recommendations based on what the ring measures — sleep, activity, stress, heart health, and reproductive patterns all combined into one picture.

The company has also been building out partnerships. Beyond Natural Cycles and Twentyeight Health, Oura added integrations with Midi Health, Evernow, Maven Clinic, and Progyny to help with menopause care. It opened its first UK retail partnership with John Lewis, making the ring available in all 34 stores in May 2024. In October 2025, Oura added new stress tracking and blood pressure features, plus redesigned its app interface.

Patents and Regulatory Standing

In September 2025, the U.S. International Trade Commission ruled in Oura's favor in a patent dispute against competitors Ultrahuman and RingConn. The decision protects Oura's core technologies as the smart ring market grows more competitive.

The Olympic partnerships add credibility to Oura's physiological tracking — validation from elite athletes that the ring can measure what matters. The fact that the ring's birth control feature is FDA-cleared is also significant. It marks one of the first times a consumer wearable has earned medical device status for this kind of health use, which opens doors for more clinical integrations in the future while also requiring Oura to meet strict regulatory standards.
