How Does the Ovulation Thermometer Work?

During the first two weeks of a woman's cycle, her body temperature is lower, while ovulation causes a rise in body temperature, caused by an increase of the hormone progesterone. By monitoring when this temperature change takes place, you can determine when ovulation takes place in your cycle.

For most accurate results, take your basal body temperature every morning before getting out of bed. Record your temperature readings with the cycle tracking app, and plan your sexual activities accordingly.

How Do I Use the OT20 Ovulation Thermometer?

The OT20 Ovulation Thermometer is suitable for both oral and vaginal measurements. It features a flexible measuring tip, is waterproof, and can be disinfected to maintain optimal hygiene.

The thermometer sounds an acoustic signal when the measurement is complete, and features automatic switch-off. You can read more about how to use the OT20 Ovulation Thermometer in the user manual linked below:

How Accurate Is the OT20 Ovulation Thermometer?

This ovulation thermometer is accurate to ±0.05°C at 35°C to 38°C, and ±0.1°C in remaining measurement ranges. It features temperature display to two decimal places.

What Is Ovy Cycle Tracking App?

The Ovy app enables you to record your entire cycle and keep an eye on it at any time on your smart phone. Ovy is designed for women who want to have children. You can download the app for free from the Apple App Store and Google Play.

Is Using an Ovulation Thermometer a Reliable Method for Family Planning?

While ovulation does cause a rise in body temperature, there are many other variables present as well that can have an impact on your body temperature. Using an ovulation thermometer to predict your fertile days can greatly improve your chances of getting pregnant, but we do not recommend using an ovulation thermometer as the sole method of contraception.
