Fertility Monitor Sensor

The DuoFertility sensor is roughly the size of a small button. It is worn under the arm where it is held in place with a specially designed adhesive. The sensor continuously collects roughly 20,000 temperature measurements throughout the night and day, which enables it to identify your body basal temperature. This data is then used to identify when ovulation has occurred, which will in turn help to identify your fertile window and the best time for you to have intercourse.

Unlike other fertility devices, with DuoFertility, you don’t have to worry about measuring your temperature every day – all you have to do is wear the sensor and get on with the rest of your life! We recommend that you wear the sensor continuously in order to improve the accuracy of your temperature measurements. If you want to go out, or if you are wearing a bikini and do not want to wear the sensor, you can remove it during the day, but it is very important that you remember to put it back on when you go to bed so that data is available every single night.

How Do I Access My Data?

Your fertility data is recorded and stored on the DuoFertility sensor, but to be able to view it, you need to transfer it to the reader. To do so, use the scroll-wheel on the reader to scroll through the function lights until the "read" icon (the DuoFertility logo) is highlighted. Once it is highlighted, the read icon will flash orange/green if sufficient recent data has been downloaded to estimate fertility. You should then press the central button of the reader and position the reader so that the central button is resting against the sensor. The reader will make a single beep to indicate that it has started reading, and two beeps (low then high) to indicate that it has finished reading. The display will then revert to flashing orange/green, and your fertility will be displayed on the reader's light scale. Reading of your data should take around 5 seconds per day of recorded data.

If you wish, you can view your fertility status in more detail on your PC through the DuoFertility software after plugging the reader into the computer with a USB cable (provided). Or if you would still like further information, you can ask one of our fertility experts to have a look at your results.
