OvaCue Fertility Monitor

Double Your Fertility IQ

The OvaCue Fertility Monitor consists of a hand-held fertility monitor with a color screen, and TWO sensors – a saliva sensor, and a cervical mucus sensor – the ideal combination for pinpointing your most fertile days in your cycle and for detecting when ovulation likely occurred. Take the guesswork out of your fertility by seamlessly reading and tracking your body’s biology clues with the OvaCue Fertility Monitor and companion website, OvaGraph. Women who know when they are fertile have a higher chance of getting pregnant during that cycle. Don’t let another month pass you by!

This product is only available for purchase in the United States.

How It Works

The OvaCue is a monitor that measures changes in the electrolyte levels in your saliva and cervical mucus that are impacted by the hormone estrogen. Simply place the oral sensor on your tongue daily and the OvaCue will record a reading of the electrolyte resistance in your saliva. The monitor will track trends in these readings, looking to identify a specific trend (called the “Cue Peak) that marks the beginning of your fertile window. Once this trend is detected, the monitor will color-in the calendar with varying shades of blue (from light to dark), indicating low to peak fertility, and providing 5-7 days advance notice of ovulation. With several days advance notice of ovulation, you are able to increase your chances of conception. The OvaCue keeps track of your current cycle day and current fertility status — and it stores up to 4 months of readings.

Once you begin use of the vaginal sensor, the monitor is able to track trends in the vaginal readings to determine when your body switches from estrogen dominance to progesterone dominance, the clue it uses to confirm that ovulation occurred.* As you move through your fertile window, signified by the blue days on the calendar, the monitor will be tracking the vaginal readings closely so that it can detect the trend it is looking for to confirm ovulation. Once this trend is detected, the monitor will display a pink box, indicating “possible ovulation”. In some cases, depending on the specific hormonal fluctuations of the user, the monitor will also display a purple box two or more days following the pink box, which also indicates “possible ovulation.” Please note that when both a pink and purple box are displayed on the calendar during a cycle, interpretation of actual reading data may be required to determine whether ovulation occurred with the pink box or with the purple box.

*Note: Vaginal ultrasound is the only method available that confirms ovulation with 100% accuracy. With the OvaCue, we can detect specific trends which indicate ovulation. Even with the display of the pink or purple box, we do recommend you continue to interpret your data to confirm that ovulation occurred successfully.

Works for Irregular Cycles and PCOS and Here’s Why

The OvaCue is used successfully by women with irregular cycles and Polycystic Ovarian Syndrome (PCOS). While other fertility monitors predict ovulation based on the attainment of a pre-determined level of a given hormone (either luteinizing hormone, estrogen, or a combination of the two), the OvaCue has no predetermined level set — rather, it interprets each reading in your cycle in relation to your previous readings. OvaCue doesn’t look for a specific reading based on statistical averages, it looks for an overall trend in your body’s own unique readings. This method of ovulation determination is particularly suitable for women with irregular cycles since a hormonal imbalance may prevent you from reaching a predetermined hormone level prior to ovulation.

For women with highly irregular cycles, it may also be necessary to interpret actual reading data (in addition to looking at the color coding on the screen of the monitor), to accurately determine your fertility status. Irregular cycles are commonly caused by hormonal imbalances. For women with a hormonal imbalance, ovulation may occur before or after the predicted time frame that the saliva sensor provides. If you happen to ovulate earlier then the oral sensor predicted — the cervical mucus sensor will be able to notify you if ovulation is actually occurring sooner. This is also the case if ovulation is occurring later than the oral reading had originally predicted.
