How It Works 

Our fertility computers are programmed to accurately determine and display the time of ovulation in the female body. Ovulation causes a slight, but noticeable rise in body temperature. When you measure your temperature with the sensor for 5-60 seconds orally every morning before you get up, the fertility computer evaluates the data and quickly recognizes your individual fertility pattern.
If you are fertile the computer will display a red light and if you are safe the computer will show you a green light. The display is reliable and valid for the next 24 hours.
