- All it takes is just a drop of saliva
KNOWHEN® Advanced Saliva Ovulation Test Kit with Fertility Monitor App Identifies five (5) most fertile days with 98.9% accuracy proven by U.S. Clinical Studies. Millions of women have infertility issues mostly caused by ovulation problems and millions more of childbearing age need to know when they ovulate.
The journey into understanding saliva’s role in fertility tracking began in 1945, when Dr. George papnicolau first noted microscopic crystal formations in cervical fluid. the phenomenon, known as ferning, is key to identifying fertile wisdom in the menstural cycle.
In 1969, Dr. Biel Cassals, a Spanish gynecologist, extended this research to saliva. His groundbreaking presentation to the Barcelona Medical Board established that hormonal changes during the menstrual cycle influence the crystallization of saliva, which mimics the arborization effect seen in cervical mucus.
Estrogen, a hormone closely linked to fertility, modulates the salinity of saliva. As ovulation approaches and estrogen levels surge, so does the salinity in saliva. This increase causes saliva to crystallize in patterns similar to those in cervical mucus, which are detectable under a microscope.
In 2009, the KNOWHEN® Advanced Saliva Ovulation Test received FDA clearance. Conducted by Dr. Hugh Melnick at the Manhattan Fertility Center, U.S. clinical studies affirmed the test's 98.9% accuracy. These studies demonstrated a significant correlation between the ferning patterns in saliva and actual ovulation, confirmed through sonographic examinations.
Nature cleverly preserves in a Woman’s SALIVA the answer to very important questions: “Am I ovulating?” and “When is the best time for me to conceive?”
Checking saliva daily will unlock the secret of a woman’s unique ovulation cycle and answer the most important question…”Could I get pregnant today?“
Researchers have studied the phenomenon of ferning in cervical fluid since 1945, when Papanicolau observed mi- croscopic crystal formations in cervical fluid (mucus).
In 1969, Dr. Biel Cassals, a Spanish gynecologist, studied the crystallization of saliva. His presentation to the Barcelona Medical Board proved a relationship between hormonal changes during the female menstrual cycle and the crystallization of saliva, indicating ferning saliva is virtually identical in appearance to the arborization effect of cervical fluid.
The hormone estrogen links saliva patterns to a woman’s fertility. As ovulation nears, estrogen increases and causes the body’s sodium levels to rise increasing the salinity of a woman’s saliva. Near ovulation the higher salt content causes the dried saliva to form crystallization patterns as seen under microscope. Both saliva and cervical mucus have shown these patterns.

In 2003, KNOWHEN® Advanced Saliva Ovulation Test was cleared and registered by FDA. U.S. clinical studies proved KNOWHEN® to be 98.9% accurate. HiLin Life Products, Inc. is globally recognized as a leader in Fertility Tests and marketing research for women’s reproductive health.
Saliva testing measures a far more gradual increase of estrogen that occurs prior to or during ovulation, and thus gives the user a greater planning “window.”
The KNOWHEN® Advanced Saliva Ovulation Test is a salivabased method proven to determine a woman’s five (5) most fertile days during her ovulation cycle — more days than any other ovulation test. In addition, fertility drugs and medications influence the LH levels in urine tests and thus can invalidate urine ovulation test results. KNOWHEN® is chemical-free and not affected by fertility drugs and medication.
