Can exercise or showering affect the OV-Watch®?
Yes. It is best to wait at least one hour after showering or vigorous exercise before wearing the Watch, but remember to never get OV-Watch wet.
Can I use the OV-Watch® 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 OV-Watch® if I am a diabetic controlled by diet (not pills or insulin)?
We believe the diabetic condition you have will not impact the use of our ovulation predictor, the OV-Watch®.

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. The sensor on the underside of the watch makes contact with the skin when you wear the watch on your wrist. Using this patented biosensor, OV-Watch detects a baseline chloride ion level for each woman and then accurately predicts ovulation based on the timing of the first peak that comes approximately 6 days before ovulation That chloride ion surge is detectable in a women’s perspiration. The OV-Watch detects the chloride surge 3 days prior to the estrogen surge, 4 days prior to the LH surge and 5 days prior to ovulation, making it an earlier predictor of ovulation than any other chemical surge during the month.

Knowing the 4 days before you ovulate not only reduces your stress level but medical literature supports that having intercourse on the 4 days before ovulation day dramatically increases your odds of getting pregnant. This is due to several factors related to sperm and egg life.

Does OV-Watch® work if I am taking fertility drugs?
In an ongoing clinical trial, OV-Watch performed as expected with fertility drugs, like Clomid. See OV-Watch success stories for more information from women who have used OV-Watch and Clomid together with success.

Note: 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.

I have used the watch for one month and have not had a fertile reading. What is wrong?
The OV-Watch® should indicate fertile days during the fertile window. The lack of detection and/or indication of detection of fertility can be due to a lack of contact with the skin (ie: the watch is not being worn tight enough), or failure of the sensor due to water exposure, or other reasons described in the user reference manual. It is also possible that you have gone through your cycle without ovulating. It is normal to have an occasional cycle without ovulating and therefore not have a fertile reading.
How tight must I attach the OV-Watch® to my wrist?
The OV-Watch® device needs to be snug on the wrist to make good contact, but not so tight as to affect blood flow to your hand.
Can the OV-Watch® improve its accuracy the longer I use it?
Unlike other ovulation predictors, OV-Watch® begins the first cycle that you use it informing you of your 6 fertile days. That is why you will see in our success stories so many women who have gotten pregnant the first month that they use OV-Watch.

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.
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 utilized to predict ovulation. OV-Watch is the first fertility predictor on the market that has the advanced technology (patented biosensor and microprocessor) to measure sweat ion changes on the skin and accurately predict not only ovulation, but the most fertile days of the cycle including the day of ovulation.

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 hours). 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.

How effective will the OV-Watch® be for me?
It is important to remember that there are no ovulation predictor devices available that can guarantee success in achieving pregnancy. However, by utilizing the advanced technology that OV-Watch® provides, you have advanced notice of ovulation and find your entire fertile window. Proper identification of your individual fertility window may shorten the time to conception from 6 months to one month for the majority of women (3 out of 4 women)6,7. Intercourse on the
fertile days that OV-Watch provides doubles your chances of conceiving as compared to LH testing.

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. The advanced microcomputer tracks your fertility status. All of these components together allow the watch to predict the days when a woman is most likely to get pregnant. The sensor on the underside of the watch makes contact with the skin when you wear the watch on your wrist. The sensor contains a non-allergenic gel that mixes with the light moisture that develops between the sensor and your skin. The gel facilitates the ionic interchange that enables OV-Watch® to predict your most fertile days of the month. This is how the OV-Watch® works as an advanced ovulation predictor. It is important not to misinform the sensor with water from a shower, water activity or the excessive sweat produced from exercising. Health Watch Systems recommends wearing the watch at night while sleeping.

What health factors could interfere with the OV-Watch® results?
The watch is designed to work on naturally ovulating women. Please refer to the Limitations of Use section (page 5) for health conditions adversely affecting the watch.
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. However, more important to finding your greatest probability of conceiving- finding your full fertile window- OV-Watch® provided up to 4 days notice prior to ovulation as compared to BBT, which provides no advanced notice of ovulation, and up to 4 days prior to ovulation, as compared to LH urine kits that provide only hours before ovulation. The trial concluded that:

“Properly used, OV-Watch gives more notice for conceiving and is not invasive.”

“This device (OV-Watch) provides the user with notice up to 4 days before ovulation during which the user may have the greatest chance of becoming pregnant.”

What if I forget to wear the watch?
If two or more days of readings are missed completely in the pre-fertile phase of your cycle the watch will forfeit the cycle and display NO DATA on the fertility status screen.
Can I use the OV-Watch® if I work night shifts or for some other reason where I have to sleep during the day?
Yes. Just make sure that you wear it for six consecutive hours each calendar day during the pre-ovulation phase of your cycle.
What can I do when I push the wrong button or push one accidentally?
The watch has a button lock feature to avoid accidental button presses. If you are in a particular programming sequence, refer to the instructions for that sequence regarding a way to cancel your actions.
What does a blank screen indicate?
First, press buttons B and C together for 3 seconds to see whether the watch is in sleep mode. If the screen remains blank, or the seconds stop counting, then the watch requires immediate service. Please contact the OV-Watch® Customer Service at 1-877-249-BABY (2229).
How can I be sure the sensor is working properly?
Refer to the Test Mode section of this guide for specific details on how to determine proper sensor functioning.
Is the OV-Watch® waterproof?
No. OV-Watch® contains a microprocessor, which cannot get wet. Take the device off your wrist when swimming, showering, bathing or even when washing your hands or dishes.
Where can I get help with a technical problem?
Call OV-Watch® Customer Service at 1-877-249 BABY (2229) for immediate assistance or email us at techsupport@ovwatch.com.
How should I store the watch when I do not need to wear it any longer?
First remove the sensor. When storing the watch for an extended period of time, it is a good idea to put it into sleep mode to conserve the battery life. Press Buttons A and B at the same time for 3 seconds to put the watch in sleep mode. The original packaging of the watch includes a plastic storage case which should be used.
Why do I have to enter in my approximate cycle length the first month?
Throughout your cycle, there are several surges of chloride ions related to hormonal changes during your cycle. See the surge graph in the quick start guide that came with your OV-Watch. The chloride ion surge that OV-Watch is looking for to determine your individual fertile window, comes about 6 days before ovulation. In a 28 day cycle, it is the first surge of Chloride ion that the watch is detecting. On a cycle that is longer than 29 days, it is the second or third surge that indicates 6 days before ovulation. By entering in your approximate cycle length, you are helping the watch to determine which surge to look for to accurately determine your individual fertile window.
Why does OV-Watch switch to fertile day 1 when I am not wearing it?
Throughout your cycle, there are several surges of chloride ions. Refer to the Quick Start Guide to see the surge graph. The surge in chloride Ions that OV-Watch is looking for, comes about 6 days before ovulation. Once it detects the surge, it holds that data and processes it with the baseline levels that it has already stored in memory. Then, when the user is 4 days from ovulation, it reads fertile day 1. Since the data is compiled at midnight, that is when it will turn to fertile day 1. When you see that reading, the surge was actually detected days before. Once OV-Watch detects the chloride surge that it is looking for, it has done its job. It will alert the user to her fertile window: the 4 crucial days before ovulation and the day of ovulation. It works similarly to the urine sticks in that they detect for the LH surge that comes hours before ovulation. Once they detect that LH surge, you can assume that you are going to ovulate in the next 12 hours or so.
Why does OV-Watch go on automatic after getting fertile day 1 reading?
OV-Watch detects the surge of chloride ions that comes about 6 days Before ovulation. Once the user sees fertile day 1, that means that the watch has detected the surge, and can predict that they are going to ovulate 4 days later. Once OV-Watch detects the chloride surge that it is looking for, it has done its job and is able to give you 4 days advanced notice of ovulation. It works very similar to the LH based urine sticks in that they detect the LH surge that comes hours before ovulation. When the user gets a positive on the stick, they can assume that they are going to ovulate in the next 0-24 hours. That advanced notice that OV-Watch offers the user makes the difference when trying to conceive.
What happens when I replace the battery in the watch and the battery low indicator does not go away?
OV-Watch takes a reading every 12 hours to determine battery life. Once a new battery has been installed, it may take up to 12 hours for the low-battery icon to reset, and then the battery low indicator will disappear.
When do I start wearing OV-Watch and for how long in my cycle do I need to wear it?
OV-Watch needs to be worn from the 1 (first day of red blood bleeding), 2, or 3rd day of your period, every day or night for at least 6 hours. It is required that you wear OV-Watch through your 4 fertile days and ovulation time. You can stop wearing it after the “NF” has returned.
In the event that you are not pregnant that cycle, please follow the directions in the manual to start a new cycle when your period begins again. If you are pregnant that cycle, then press button A and B together and hold for a few seconds. This will put the watch to sleep to save the battery for future use. Also, please send us your story of success with OV-Watch.
