Fertility Tracker Guarantees Pregnancy Within One Year

Until recently, detecting the time during a woman’s cycle when she is most likely to conceive has been imprecise. Methods included measuring basal temperature spikes, which only detect ovulation after the fact, or urine tests that indicate a surge in luteinizing hormone, which predict ovulation is imminent within 12-36 hours. Both require meticulous recording of data by the user. Ava Science offers a fertility tracker that requires much less effort on the part of the user. Ava, a device that is worn on the wrist like a bracelet while the woman is sleeping, measures key physiological parameters to detect signals that mean the user is entering the fertile window. The data is then synced with an app on the user’s smart phone. One of the factors Ava analyzes is resting pulse rate. According to a recent study using the device, researchers observed a significant increase in pulse rate during the fertile window compared with the menstrual phase (2.1 beat-per-minute, p < 0.01). The device also measures other variables such skin temperature, breathing rate, heart rate variability ratio, blood perfusion, movement (which determines between light and REM sleep), and amount of sleep. Ava must be worn a minimum of four hours per night, with at least three hours of sleep for the data to be meaningful. The tracker can detect an average of 5.3 fertile days per cycle at 89% accuracy, although the company says that algor...
