OvuSense versus other methods - the clinical evidence

An analysis of available clinical studies provides the following table comparing sensitivity, positive predictive value and accuracy for Ovulation Prediction and Detection for each of the available methods.

Sensitivity = How many positive ovulations does the method predict or detect?, Positive Predictive Value = How many of the predicted ovulations does the method get right?, Accuracy = How many positive and absent ovulations does the method predict or detect correctly?

Click on the "i" icon next to each method in the table, or directly on the method in the table on mobile devices to find out more about the clinical evidence.

OvuSense, for your whole fertility journey

OvuSense is different from anything else you may have heard of or used before for monitoring fertility at home. That's because it measures continuous Core Body Temperature using a specially designed vaginal sensor proven in over cycles of use. The vaginal sensor is used overnight only, and data are downloaded to the dedicated OvuSense App each morning. OvuSense provides live updates predicting ovulation up to 24 hours in advance using current cycle data, then confirming the date of ovulation. The OvuSense Pro portal then allows the user and their doctor to work out why they might not be conceiving and track the effect of medications or treatment if that's needed.
