How Accurate is DuoFertility?

When ovulation occurs, there is a small increase in your body basal temperature (BBT). BBT is the lowest temperature your body reaches – your body usually reaches this temperature during deep sleep and your temperature increases again when you wake up. This small increase in BBT occurs within 48 hours of ovulation and remains elevated until your next period or during pregnancy.

DuoFertility works out when you are sleeping most deeply, so there are no disruptions to your temperature measurements from late nights, early mornings, or interrupted sleep.

The technology behind the DuoFertility fertility monitor identifies your fertile days with reassuring accuracy. DuoFertility takes 20,000 times more data than conventional fertility monitors, creating an incredibly accurate picture of your cycle which can help you to gain a greater understanding of your fertility.

DuoFertility also allows you to record other fertility clues such as the results of LH tests, cervical mucus quality as well as other factors related to your fertility and general well being. These clues create a more detailed picture of your cycle allowing the fertility specialists to review it in greater detail.
