KNOWHEN® Saliva Fertility Tester is 98.9% accurate in measuring a woman’s fertility by using her saliva. Estrogen increases in the blood stream as it is secreted by the maturing follicles. During the time estrogen increases in the blood, the saline content of saliva increases. The increasing salt in saliva will cause a crystalline pattern to develop as the saliva is allowed to dry naturally. Once the estrogen has begun to peak, right before the release of a mature egg, the crystalline pattern looks just like the leaves of a fern. This is called ferning. This is a woman’s fertile period when she is capable of conceiving.
No urine sticks. No hormones needed. It is has been clinically tested the U.S. and cleared by the Food and Drug Administration (FDA). Simply apply a little saliva to the microscope in the KnowWhen kit, wait for it to dry, and check for the ferning pattern indicating you have entered the fertile period of your cycle.
KNOWHEN® is a cost effective way for women to determine their fertility window and to know when they are most likely ovulating. This gives women the precise knowledge they need to make a decision about whether or not they want to become pregnant.
