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.Read More…
Why do ion concentrations change as women approach ovulation? Does this effect help in predicting ovulation?
Researchers in the late 50s and early 60s noted that numerous salts (chloride, sodium, potassium) in a woman’s sweat fluctuated in relation to the menstrual cycle. Chloride levels are low at the start of the menstrual cycle and peak three times during the cycle.Read More…
How accurate is OV-Watch as a fertility predictor?
OV-Watch clinical testing for FDA clearance was conducted by Duke Clinical Research Institute. For the primary endpoint of the study, accuracy of prediction of ovulation, OV-Watch was deemed “substantially equivalent” to LH testing and outperformed BBT. Read More…
What is the difference between a fertility window and ovulation day, and how does identification of each affect my ability to conceive?
Your ovulation day is defined as the day that the egg is released from the ovaries and makes its way to the uterus. Your probability of pregnancy on this day is about 5% according to an article by Dunson et.al in Statistics in Medicine (2001). LH test kits identify ovulation day for you. See chart below for day specific probabilities of pregnancy through out your fertile window.Read More…
How effective will the OV-Watch, ovulation predictor, be for me?
The clinical trials for OV-Watch FDA 510K medical device clearance, conducted at Duke University and Thomas Jefferson in Philadelphia, compared OV-Watch to the LH urine testing (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”.Read More…
What type of fertility information does OV-Watch provide?
To better understand how OV-Watch ovulation predictor works, let us explain how all components function. OV-Watch consists of a wristwatch-like device that comprises a timepiece, a biochemical sensor, and an advanced microcomputer. The biochemical sensor measures sweat ion changes on the surface of the skin.Read More…
Can the OV-Watch® improve its accuracy the longer I use it?
While you are wearing OV-Watch, it takes a reading every 30 minutes up to 12 readings per 24 hours period. That data is used to properly determine your individual fertile window. Having intercourse during the fertile window that OV-Watch provides doubles your probability of conception as compared to LH testing.Read More…
What is the fertile window? How does it affect my ability to get pregnant?
Your fertile window, as defined by Dr. Wilcox in the New England Journal of Medicine in 1995, is the 6 days of the month during which intercourse can lead to pregnancy. Using the data from Dr. Wilcox study, Dunson, et al., published data in Statistics of Medicine in 2001 showing day specific probabilities of conception during the fertile window. See chart below for the day specific probability of pregnancy for each day of the fertile window.Read More…
Does OV-Watch® work, if I'm taking fertility drugs?
The watch should continue to work as long as the fertility drugs do not mask the physical symptoms of ovulation or the signs of ovulation. Herbs and fertility supplements have not been studied with OV-Watch. Read More…
Can I use the OV-Watch® to predict ovulation if I am still taking birth control pills?
No. The use of the pill would definitely affect the results of predicting ovulation, since the woman will not ovulate. Women on the pill would have no need to use any form of ovulation predictor product since if they were on birth control pills they would not be trying to get pregnant. If you are trying to get pregnant, discontinue use of your birth control pills before you begin using OV-Watch.
Can I use the OV-Watch, an ovulation predictor, if I am a diabetic controlled by diet (not pills or insulin)?
The OV-Watch is a wristwatch-like device that comprises a timepiece, a biochemical sensor, and an advanced microcomputer. The biochemical sensor measures sweat ion changes on the surface of the skin. The advanced microcomputer tracks your fertility status and acts as an advanced ovulation predictor. All of these components together allow the watch to predict the days when a woman is most likely to get pregnant. Read More…
How does identification of my fertility window affect my ability to conceive?
Utilizing your entire fertile window when you are trying to conceive makes all the difference. The primary benefit of monitoring and utilizing your complete Fertility Window is that you maximize your probability of conceiving. Assuming that you have intercourse during the 4 days before ovulation, studies have shown that you more than double your chances of conceiving that month. Read More…
Why is the fertile window chart in the manual different from the one on the OV-Watch website?
The fertility window data shown in the manual for OV-Watch and the fertility window data shown on the OV-Watch website may show different data points but essentially are supporting the same premise. Read More…
I have an irregular cycle, can I use OV-Watch?
There is a difference between an “irregular cycle” and “irregular cycle length”. If you have an “irregular cycle” then that means that you are not ovulating every month. As you know, you need to ovulate to get pregnant, so on the months that you do ovulate, intercourse on the fertile days that OV-Watch detects will increase your chances of getting pregnant. Read More…
I am using urine sticks, charting my temperature and using OV-Watch and they are all telling me something different. Why?
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 BBT. It senses the chloride ion surge on the surface of your skin that comes approximately 6 days before you ovulate. That surge is an earlier indication of pending ovulation than LH. OV-Watch provides you your entire fertility window- the 4 days before and your time of ovulation.Read More…
How does the probability of conception change during the days near ovulation?
he probability of conception increases as one approachs the day of ovulation, with your cumulative probability of getting pregnant totaling 72% on the 4 days prior to ovulation (assuming intercourse on each of the 4 days). This is because sperm can live for up to 6 days in the reproductive tract. Read More…
How does the OV-Watch compare to the ClearBlue Fertility Monitor?
The technology behind the OV-Watch® fertility monitor is vastly different than the technology of the ClearBlue Fertility Monitor. The ClearBlue Easy Fertility Monitor tests for the presence of leutenizing hormone (LH) and estrogen in your urine, and requires you to test your urine anywhere from 10 to 20 days during your cycle using urine sticks. It can be messy and, depending on how long or irregular your cycle is, you may have to use an additional set of 10 test sticks. Some women do not like handling bodily fluids so the testing process can be stressful. Additionally, if you are taking Clomid, the ClearBlue Easy Fertility Monitor may not reliably detect your high fertility. Read More…
How is the OV-Watch different from other ovulation predictor test kits?
For the past decade or so, the standard ovulation prediction test involved checking the presence of leutenizing hormones or LH in one’s urine. This kind of ovulation prediction test only reveals a small window of fertility. Using this type of ovulation prediction test can be messy, frustrating and stressful as it requires one to urinate on a test strip or digital wand. Read More…
