A “personal ovulation microscope” allows you to predict fertility by observing the visual changes that take place in your saliva throughout your cycle. When a woman is about to ovulate, her saliva begins to form a distinct fern-like pattern (when viewed under a microscope) due to an increase in the level of estrogen present. This ferning pattern begins to appear around 3 days prior to ovulation.

With the ovulation microscopes, you simply apply saliva to a slide or lens and wait for the sample to dry. The sample is then viewed through a microscope allowing you to identify the fern-like pattern and predict ovulation. This ferning pattern can be easily identified when examined under the power of the microscope, helping you predict fertile or infertile times in your cycle.
