We help couples get pregnant and stay pregnant.
Learn how OTO is helping couples manage stress and unlock fertility.
What is OTO?
OTO helps couples measure and manage stress to get pregnant and stay pregnant.
Using medical-grade wearable technology and machine learning, OTO generates an in-app personalized daily activity plan with specific recommendations to support natural hormone production and build your stress management capabilities. These processes underpin fertility and impact your chances of conception.
Did you know?
Studies show that fertility treatment increases physiologic stress and lowering ‘fight or flight’ activity is associated with improved odds of conceiving.1,2
Your fertility team has partnered with OTO to help you measure and manage stress throughout your fertility journey and improve fertility outcomes
Why OTO?
Increase stress resilience. Improve your capacity to manage the stressors of fertility treatment with specific exercise, rest, and recovery tasks from Fertility Coach.
Improve fertility outcomes. Reducing "fight or flight" activity, adapting your "brain/central nervous system" activity, and shifting "energy supply system" are all correlated with a higher likelihood of getting, and staying, pregnant. 2
Safe and non-invasive. The OTO Chest Strap and Sensor is FDA-approved for research purposes and poses minimal risk. Activity recommendations from the OTO Fertility Coach are personalized to you and supported by decades of research for maximum safety and efficacy.
Convenient. From the assessment to activities, every part of the OTO experience can be performed from the comfort of your home. No fancy gym equipment required!

OTO Chest Strap & Sensor
Your OTO Chest Strap and Sensor isn’t your average wearable. It’s medical-grade technology that measures 50+ metrics related to stress and your ability to adapt to it, including EEG/ DC potential, ECG, and HRV. Together, these metrics paint a picture of your physiological stress and capacity to manage it.
OTO Fertility Coach
Your OTO Fertility Coach turns complex data from the OTO Chest strap and Sensor into an in-app personalized daily activity plan, informed by decades of research on stress. Think of Fertility Coach as a science-driven personal trainer in your pocket, offering specific recommendations to improve your fertility outcomes.

FAQ
What exactly does OTO measure, and why does it matter for fertility?
OTO's chest strap sensor tracks over 50 biomarkers—heart rate, heart-rate variability, EEG/DC signals and more—that together paint a picture of how your body responds to and recovers from stress. Elevated or poorly managed stress responses can impair implantation and early pregnancy maintenance, sometimes more than age or BMI.
Is wearing the biosensor safe, and will it interfere with my daily life?
Absolutely. The OTO chest strap is FDA-approved and medical-grade. You wear it for just a few minutes each day—like putting on a heart-rate monitor—so it won't disrupt work, exercise, or sleep. It's noninvasive, and you only need 3–5 minutes daily for the quick stress-response assessment.
How do you use my data, and who sees it?
Your daily assessment results sync securely to the OTO app and our clinic dashboard. Only your care team will review trends. We use that information alongside your treatment protocol to personalize lifestyle tips and support your stress resilience to improve your chances of success.
Will this delay or complicate my existing treatment plan?
Not at all. OTO is designed to run alongside any medical protocol. We integrate the device into your routine without altering medications or procedure dates. It simply adds an extra layer of tailored support.
What should I do if my stress score trends higher than expected?
If your daily score indicates elevated stress, the OTO coach suggests small, evidence-based tweaks—like breathing exercises, gentle yoga, or a brief nature walk—that take 5–15 minutes. We review your data and iterate as needed.
How quickly will I see meaningful trends or improvements?
Most patients see stable trends within 3-5 weeks of consistent daily assessments. In 2–3 weeks, enough data emerges to identify stress "hot spots" and create personalized activity plans to improve overall stress biology and response.
Does insurance cover OTO Fertility?
OTO Fertility is covered by most HSA/FSA plans, but coverage varies. Some insurers cover remote monitoring devices; others consider it a wellness tool. Our billing coordinator can explore coverage options or arrange financing.
How does this differ from general stress-management apps or wearables?
Consumer wearables track activity or sleep but don't measure the neurophysiological signals OTO does (like EEG/DC). OTO's algorithms translate data into fertility-specific insights for personalized guidance during critical phases.
Will using OTO actually increase my chances of getting pregnant?
While no tool can guarantee pregnancy, studies show that patients optimizing stress-response metrics with OTO interventions see measurable improvements in implantation and early pregnancy retention.
