by OvuSense • Model: OvuCore M300SP
The OvuSense OvuCore is a regulated Class II medical device that uses a vaginal sensor to track continuous Core Body Temperature (cCBT) throughout the night. Unlike standard oral thermometers, it measures temperature every five minutes with 1/1000th of a degree resolution. This high-precision data allows the system to track the rise and fall of progesterone, enabling it to predict ovulation 24 hours in advance and confirm the exact date of ovulation once it has occurred. It is clinically validated for all cycle types, including PCOS and irregular cycles.

Evidence-based evaluation by medical professionals
"OvuSense OvuCore is a uniquely powerful fertility monitor that uses core body temperature to provide laboratory-grade ovulation confirmation, making it the premier choice for women with PCOS."
The OvuSense OvuCore Fertility Monitor is a sophisticated diagnostic system designed to overcome the limitations of skin-temperature wearables and hormone-based urine tests. The device consists of a medical-grade, vaginal sensor worn overnight, which records thousands of data points to determine an extremely accurate 'Core Body Temperature' (CBT). Unlike traditional basal body temperature (BBT) which relies on a single morning measurement, or skin sensors affected by environmental factors, OvuCore measures internal shifts unaffected by external variables. This technical approach is particularly beneficial for users with Polycystic Ovary Syndrome (PCOS) or irregular cycles, as it identifies the physiological shift of ovulation regardless of hormonal fluctuations that often cause false positives on LH strips. Clinical validation supports a 99% accuracy rate for confirming the date of ovulation and a 96% positive predictive value for 24-hour advance prediction. The system integrates with a data-rich mobile application and includes a clinician portal, allowing users to share longitudinal cycle data directly with fertility specialists. While the requirement for internal insertion may be a barrier for some, the diagnostic depth and clinical reliability of the OvuCore system place it at the top of the fertility monitoring category for complex reproductive profiles.
