Pinpointing Your Fertile Time with the OvaCue Fertility Monitor
When it comes to conception, timing is everything. Once ovulation occurs – the moment at which the egg is released from the ovary and pushed down the Fallopian tube – the clock starts ticking. An egg is only viable for up to 24 hours after ovulation, so sperm must get to work immediately if fertilization is going to be successful.
Therefore, to have the very best chance of conceiving, sperm must be ready and waiting in the Fallopian tube when the egg is released. But, because sperm can only live for 3-5 days inside the female reproductive tract, there are really only a few days during each menstrual cycle that intercourse can lead to conception.
As a result, predicting ovulation is essential when you are trying to conceive. There are a variety of ways to identify your fertile window.
Some women are able to pinpoint their fertile days by watching for changes in the consistency of their cervical mucus (the presence of “egg-white” cervical mucus can indicate that ovulation is just around the corner), or by charting their basal body temperature.
Other women prefer more sophisticated ovulation prediction tools, such as urine-based tests kits (used to identify the surge in luteinizing hormone that occurs 12-48 hours before ovulation) or electronic fertility monitors, such as the OvaCue Fertility Monitor.
How Does the OvaCue Monitor Work?
The OvaCue fertility monitor is an electronic fertility monitor manufactured and distributed by Fairhaven Health. The hand-held monitor has a color-coded LCD screen and comes with a spoon-sized oral sensor and a vaginal sensor.
There is also a mobile version of the OvaCue Fertility monitor available. Now you can get the same accurate technology right on your iPhone or other iOS devices.
Unlike other electronic fertility monitors that require urine testing, the OvaCue predicts and confirms ovulation using the patented Electrolyte Method.
As you move through your menstrual cycle, the levels of various hormones circulating in your body go up and down, and these hormonal fluctuations produce changes in the electrolyte (such as sodium and potassium) characteristics of your saliva and cervical mucus.
Using measurements obtained from the oral and vaginal sensors, the OvaCue tracks trends in electrolyte levels, allowing the monitor to identify the hormonal changes that occur during the ovulatory process, thereby allowing it to predict and confirm ovulation.
How do I use the OvaCue Fertility Monitor?
Beginning on Cycle Day 2 of your menstrual cycle, you will take an oral reading each morning, at the same time every day, before you eat or drink anything.
The monitor will store and track trends in this oral readings, looking specifically for the Cue Peak trend that indicates ovulation is 5-7 days away.
Once this Cue Peak trend is detected, the monitor will color-in the calendar with varying shades of blue (from light to dark), indicating low to peak fertility.
Once your menstrual bleeding has ended, you will begin taking vaginal readings each day.
The monitor will track trends in these readings, looking specifically for a low vaginal reading followed by a significant rise in the vaginal readings.
Once the monitor detects this trend, it will display a pink box confirming ovulation. The pink box indicates that the shift from estrogen dominance to progesterone dominance has occurred and that the fertile window is closed.
While only a vaginal ultrasound can confirm successful ovulation with 100% accuracy, the OvaCue provides valuable information about the hormonal changes that are necessary for ovulation to take place.
Why Do Women Prefer the OvaCue to Other Ovulation Prediction Tools?
- The OvaCue does not require urine testing, which eliminates the mess associated with urine testing and the cost of purchasing test strips.
- The OvaCue provides up to 7 days advance notice of ovulation, while most other ovulation prediction methods and tools predict ovulation only a few days before it occurs
- The OvaCue tracks trends in hormones instead of measuring absolute levels of hormones, making it a helpful tool for women with hormonal imbalances or deficiencies
How Accurate is the OvaCue Fertility Monitor?
In studies funded by the National Institutes of Health, the OvaCue Fertility Monitor has demonstrated 98% accuracy in predicting ovulation.
