 Predicting Ovulation
How accurate is chloride at predicting ovulation - especially compared to LH testing?
OV-Watch fertility predictor is clinically proven, patented, and FDA-cleared. It is a lightweight, wrist–mounted, chloride ion-sensing medical device. It works entirely different from the LH urine kits and saliva monitors. While LH urine kits look for the presence of lutenizing hormone in the urine, and saliva monitors look for varying levels of estrogen, OV-Watch detects the chemical surge of chloride ions on the skin, which is an earlier predictor of a woman’s fertility.
OV-Watch's fertility prediction is predicated on advanced technology but established science. References related to chloride ion changes during a woman's menstrual cycle have been in medical literature dating back to the 1960's. However, until OV-Watch’s advanced and patented technology was developed, the science of Cl ion surges during a woman’s menstrual cycle could not be used to predict ovulation. OV-Watch is the first fertility predictor product able to measure sweat ion changes on the skin and accurately predict not only ovulation, but find the most fertile days of the cycle in addition to the day of ovulation.
See the recent news media about Chloride ion changes predicting ovulation.
Clinical Support: The clinical trials for our FDA 510K medical device clearance, conducted at Duke University and Thomas Jefferson in Philadelphia, compared OV-Watch to the LH urine kits (since that was the only predicate device). The trial results concluded that:
OV-Watch is equivalent in predicting ovulation; however, this was only part of the results. Additionally, OV-Watch was shown to "provide the user with notice up to four days before ovulation during which the user may have the greatest chance of becoming pregnant".
That is why the cumulative conception rate is almost double with OV-Watch. To put it simply, 66% more pregnancies are estimated to occur by month 6 with OV-Watch over LH kits.
Sandra Ann Carson, the President of the American Society for Reproductive Medicine stated, “Although LH peaks accurately detect ovulation, they do not identify the pre-ovulatory fertile period. Up to two thirds of pregnancies are conceived at or prior to ovulation.” The OV-Watch is non-invasive and provides more notice for maximizing a couple’s chance of conceiving. This is in line with fertility experts' current thoughts that to maximum one's chance of conceiving, the sperm needs to be waiting for the egg (since sperm can live for up to 5 days in the genital tract and the unfertilized egg only lives for 12-17 hours5). OV-Watch’s ability to provide more notice also provides another distinct advantage: It lowers the stress level for a couple trying to conceive. Sometimes, that can make all the difference.
