Measuring changes in core body temperature provides a valid method to detect ovulation and increase fertility. 'OvuSense' is a novel vaginal sensor that can predict the fertility window by recording and analysing the changes in intravaginal temperature records. This study aimed to determine patients 'acceptability and satisfaction after using OvuSense'. We approached 13 women to complete a patient satisfaction survey after using OvuSense in a prospective, longitudinal, comparative study, to test its validity and accuracy in detecting ovulation over a minimum period of three cycles. All 13 women agreed to participate in this survey. The majority of the participants found the usage of the reader to be very easy; 76.9% of the women said it was extremely comfortable to use the device during the night and 76.9% found the idea of using the intravaginal reader to be very convenient. Overall, 69.2% of women were extremely satisfied using the device. The idea of detecting intravaginal core body temperature changes appears to be highly acceptable by women.
