OTO Fertility is more than a wearable fertility tracker. It decodes your stress and recovery periods to give you science-backed clarity that can help you take more control of your Path to Parenthood™.
Trusted by leading research institutions
Via DC-EEG, OTO captures your brain's energy state and CNS readiness, a window into how your body is regulating stress and recovery that no other device provides.
Clinical-grade electrocardiography captures cardiac function, heart rate variability, cardiac readiness, and recovery state. HRV is a critical marker for assessing reproductive health and how stress is affecting your system.
Calculated from the AFA of your ECG, this gives direct insight into your metabolic pathways and how your body is supporting energy production, which ties directly into oocyte development and reproductive function.
Most consumer wearables calculate HRV from optical pulsometry, a method with known accuracy issues that degrade further with individual skin pigmentation. OTO calculates HRV directly from ECG, delivering the clinical-grade accuracy your fertility team needs to make real decisions.

Your Fertility Index is a longitudinal trend metric built from your brain, nervous system, and cardiac data. It updates every 5 assessments, so the number you see reflects a real trend, not day-to-day noise, and tells you and your care team how ready your body is for conception.
OTO uses three readiness zones to guide your journey. Patients who reach the Optimal Zone have seen up to an 85% conception rate.
Moving toward the Optimal Zone isn’t left to chance. Each day, OTO delivers an Adaptive Activity Plan personalized to your current readiness, the recovery, nutrition, and lifestyle steps that are essential to optimizing and improving your biological signals over time.

OTO was easy to use and follow. After having trouble conceiving and keeping a healthy pregnancy, we tried OTO Fertility, got pregnant and had our baby this year. This changed our lives.
