KNOWHEN Saliva Fertility Monitor

What It Is

A reusable ovulation monitor that uses saliva to track fertility on a daily basis.

Why You Should Use It

The KNOWHEN monitor offers a 98% accurate result, backed by US clinical studies, and is FDA-cleared way to help a woman who is trying to conceive. By tracking her ovulation cycle daily, a women can increase her chance to conceive and can utilize natural family planning methods.

How to Use It

When you wake up in the morning, remove the lens cover and lens housing. Even before brushing your teeth or gargling coffee, apply a thick drop of saliva to the glass surface and let it dry (10–15 minutes). Then replace the lens housing onto the tube. Hold the monitor up to your eye to view the image, then compare it with the images on the provided fertility chart to determine whether or not you’re ovulating. Keep track of results by inputting your data into the KNOWHEN mobile app.

How It Works

When a woman ovulates, her estrogen levels increase. This means a higher percentage of salt in a woman’s body; that’s where the KNOWHEN monitor comes in. Under the monitor’s 60x magnification, laboratory-quality lens, dry drops of saliva appear as fern-like shapes, dictating whether or not a woman is ovulating.
