The Science Behind OvaCue

The OvaCue predicts ovulation using the patented Electrolyte Method™ – a technique that has been demonstrated to be 98.3% accurate in predicting ovulation in clinical studies overseen by the National Institute of Health.

Here’s how it works: Throughout your monthly cycle, your body retains or discards varying amounts of minerals, such as sodium and potassium (electrolytes). The OvaCue tracks the changes in these electrolyte levels in your saliva over time and processes this information to predict your time of peak fertility.

About a week before ovulation, a high point in the salivary readings of electrolytes is reached, corresponding with the maturation process of the dominant follicle (ovum). The measurement of this phenomenon is what allows the OvaCue to provide an accurate prediction of ovulation several days in advance.

As you get closer to ovulation, your body begins to produce estrogen, causing a definite change in the electrolytes in the reproductive tract. Estrogen secretion increases and the electrolyte content of the vaginal mucus changes, causing the OvaCue vaginal readings to decline. About 12-24 hours before ovulation your body switches to progesterone dominance, causing a sharp increase in vaginal readings, which confirms ovulation and marks the closing of your fertile window.

How To Use the OvaCue Fertility Monitor

While the science behind the OvaCue Fertility Monitor may be complex, actually using the monitor to predict fertility is quite simple.

Starting on day two of your cycle, place the spoon-sized oral sensor on your tongue for five seconds first thing each morning before eating, drinking, or brushing your teeth. Then once menstruation ends, begin use of the vaginal sensor daily (at the same time each day). The OvaCue interprets your oral and vaginal readings, and automatically computes:

  • Your fertility status for today (darker colors equal higher fertility)
  • Your peak fertile days for this cycle (the days in which you have the best chance to conceive)
  • The day you likely ovulated*
  • The start and end of your fertile window (the range of days in the cycle you are most likely to conceive)

Interpreting your personal ovulation calendar:

In short, the OvaCue takes the guesswork and stress out of identifying your most fertile days of the month. With the OvaCue, you can plan up to a week in advance for the best chance of conception.

When trying to conceive, plan to have intercourse daily on the days the OvaCue defines as high and peak fertility. Remember that you must have intercourse before ovulation in order to conceive. 

* 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.
