Product Description The OvaCue Fertility Monitor® is a handheld ovulation diagnostic device. OvaCue measures the mix of electrolytes in saliva, then stores and processes that information to precisely define peak fertility time. By measuring changes in electrolyte concentration and ratios in saliva, the OvaCue predicts the optimal time for conception. Daily measurements using a spoon-shaped sensor placed on the tongue for five seconds allow women to detect the following with a push of a button: Fertility status of current cycle day, Beginning and end of fertile period, Days of maximum fertilityin advance. The OvaCue comes complete with everything you need to track your fertility for a lifetime. Each order includes: 1 yr manufacturer's warranty Free technical support Free shipping (U.S. only) Sensors in aseptic packaging All necessary batteries and connectors Complete owners manual Includes vaginal sensor. The OvaCue Vaginal Sensor measures electrolyte changes in vaginal mucus, just as the oral sensor measures electrolytes in saliva. With these measurements, it confirms your LH surge, which usually happens the day before ovulation and marks the change from estrogen to progesterone dominance, indicating ovulation has occurred. While the vaginal sensor is not required for predicting ovulation, most of our customers elect to purchase one. If you are uncertain about whether you are ovulating, the vaginal sensor will give you a clear answer. It also gives you the added confidence that the OvaCue is indeed predicting your date of ovulation accurately.
