With the Fertility Tracker®, you get 6 slides so that you can then easily compare previous patterns with one another. It can be used as an effective aid in the detection of ovulation during the menstrual cycle through identification of increased system electrolytes which generally precede ovulation. The basis of fertility tracking with the Fertility Tracker® has to do with the estrogen levels in your saliva.
The Science behind Fertility Tracking with the Fertility Tracker®
During a female’s cycle, she will have estrogen surges which then cause salt crystals to appear in the saliva and cervical mucus. When closely viewed under a microscope such as the Fertility Tracker®, you can then determine when you are most fertile. As estrogen levels peak during the period when a woman is most fertile, more and more crystals will appear in the saliva sample. Just before ovulation occurs, the crystals then begin to touch and form what appears to be a fern leaf. This “fern leaf” pattern indicates that ovulation is going to begin to occur within the following 24 to 48 hours – the time when you are most fertile. Studies conducted in Naples, Italy noted that salivary ferning is a solid method for determining a woman’s fertile period.
