How It Works

The DuoFertility fertility monitor maximises your chances of getting pregnant naturally. It uses a much more sophisticated version of the body basal temperature (BBT) measurement method to identify when you are most likely to get pregnant, up to six days in advance. This gives you plenty of time to plan intercourse for the best time of the month.

The DuoFertility fertility monitor consists of a small sensor and a hand-held reader. The sensor is attached to an adhesive patch, about 3cm in diameter, which is worn discreetly under the arm. It records your temperature continuously and determines when you have ovulated using a much more sophisticated version of the basal body temperature (BBT) method. The technology has been shown to be 99% accurate at detecting the most fertile days of a women’s cycle, and has completely eliminated the need to wake up early to take temperature measurements.

The sensor automatically measures and records your skin temperature, taking approximately 20,000 temperature measurements while you sleep (compared to just one measurement per day by most competing products). This allows easy detection of the upward shift in basal body temperature which is associated with ovulation.

Data is transferred from the sensor to the DuoFertility reader wirelessly. You will then be able to see a simple display of your fertility status over the next six days on your reader, giving you plenty of time to plan a romantic evening in! You can consult the reader at your convenience - there is no need to have it with you all the time, and you don't have to use it at any particular time of the day or week.

The DuoFertility reader can also combine the temperature measurements collected by the sensor with additional fertility clues that you may record such as cervical mucus quality and menstruation. This allows it to determine your day of ovulation even more precisely, with 99.7% accuracy.

You also have the option to view more information about your cycles by simply plugging the reader into your PC. This will allow you to visualize your temperature data and add or edit more fertility information. In addition, you can ask for an in-depth report about your cycles from one of our fertility specialists. It may be helpful for you to discuss this with your doctor and this may prove useful for the early detection of any potential fertility problems.
