Your Path to Parenthood™ Starts Here
The next breakthrough in fertility isn’t another treatment, it’s understanding your body better. OTO Fertility decodes how stress affects your system to reveal your Fertility Zone, the state where conception is most likely.
Redefining What’s Possible in Reproductive Care
OTO Fertility is transforming fertility care by combining stress biology, precision diagnostics, and continuous support. As the first predictive, clinical-grade fertility diagnostic, OTO gives patients and their care teams the clarity and control to move confidently along the Path to Parenthood™.
Capture over 50 real-time body signals through a simple daily assessment with the OTO Fertility device.
Our proprietary algorithm translates your biometric data into a clear, actionable fertility score that reflects your body’s readiness for conception.
Receive daily insights and evidence-based recommendations designed to help you achieve and maintain your optimal Fertility Zone.

All TestimonialsThe Technicals
Sensing & Monitoring
Biomarkers Tracked
Captures ECG signals from the chest and wrist and EEG readings from electrodes on the thumb base and forehead to measure autonomic and central nervous system activity.
Signal Precision
Records ECG at >500 Hz, providing high-resolution waveform data (P, Q, R, S, T segments) and precise R–R interval analysis.
Fertility & Stress Indicators
Combines Heart Rate Variability (HRV) and Amplitude-Frequency Analysis (AFA) to assess stress levels, adaptive capacity, oxidative stress, and hypoxia.
Analytical Strengths
Comprehensive Metrics
Generates 20+ validated physiological parameters reflecting autonomic regulation through statistical, spectral, and non-linear methods.
Global Standards
Applies Western HRV standards and Soviet-developed metrics correlated with reproductive health outcomes.
Regulatory & Quality Compliance
FDA Cleared
Built with FDA-certified components and cleared as medical-grade diagnostic hardware.
Manufacturing Controls
Produced in facilities certified under ISO 9001:2015 and ISO 13485:2016, ensuring full traceability, risk management, and quality system oversight for medical devices
Clinical Edge
Unlike optical sensors, OTO’s ECG-based system detects cardiac and stress dysfunctions often missed by HRV-only wearables, enabling real-time insight into stress resilience and readiness.
Functional Role
Purpose
Extends OTO’s electrophysiological monitoring to a wrist form factor for everyday wear and continuous use.
Integration
Works in sync with OTO Life App and OTO Insights to capture ECG, HRV, and EEG-derived signals throughout fertility and pregnancy.
Diagnostic Framework
Proprietary Algorithms
Employs the same patented models as the Biosensor to evaluate autonomic and CNS balance, stress resilience, and adaptive capacity.
Unified Methodology
Maintains consistent medical-grade accuracy under the same clinical framework.
Regulatory & Quality Compliance
FDA Cleared
Certified for medical-grade physiological monitoring under FDA review.
ISO Manufacturing
Hardware manufactured under ISO 9001:2015 and ISO 13485:2016 quality management standards, ensuring precision assembly and process control.
Unified Data Hub
Connectivity
Pairs with OTO Biosensor and Cira to display live ECG, HRV, and EEG-derived direct-current (DC) potential data.
Data Integration
Consolidates multiple physiological streams into a single dashboard for clinicians and users, supporting continuous reproductive health monitoring.
Key Insights
Metrics Displayed
Stress level, functional reserve, adaptive capacity, readiness for exertion, and neuroendocrine balance.
Clinical Utility
Provides dynamic visualization of CNS and ANS responses during fertility treatment and pregnancy.
CNS Profiling
DC Potential Tracking
Measures EEG-derived DC potential (0–0.5 Hz) to interpret CNS activation and regulatory tone.
Functional Insights
Identifies mental readiness, stress resilience, and energy expenditure to assess neurofunctional efficiency.
Data Protection & Security
HIPAA Compliant
All collected data is encrypted, anonymized, and managed in accordance with U.S. HIPAA laws to safeguard patient privacy.
End-to-End Security
Uses secure transmission protocols and restricted database access to protect health information during storage and transfer.
Data Intelligence
Algorithmic Processing
Synthesizes ECG and EEG data through 50+ proprietary algorithms, analyzed across six statistical dimensions (mean, median, trend, variance, SD, CV).
Validation Framework
Applies paired t-tests and Wilcoxon signed-rank tests to ensure signal significance and data integrity.
Predictive Modeling
Feature Mapping
Produces 1,900+ physiological features per user across six IVF cycle phases to forecast fertility success and pregnancy probability.
Machine Learning
Identifies key biomarker combinations predictive of adaptive efficiency and reproductive health outcomes.
Clinical Application
Integrated Monitoring
Correlates CNS, ANS, and cardiac signals to detect stress and neuroendocrine imbalance.
Treatment Optimization
Provides clinicians with personalized insights to improve IVF timing, reduce risk factors, and enhance prenatal care.
