Worn like a regular watch, the OV-Watch Fertility Predictor takes a unusual approach to predicting ovulation. Rather than using hormones in urine, the OV-Watch measures the changes in the salt content of a woman's sweat to determine her fertile period and ovulation. The watch is worn starting in the first three days of a woman's menstrual cycle and must be worn for at least six hours a day, usually at night. The watch will take measurements every 30 minutes and then display which days are a woman's fertile days and which day she's ovulating. Minimal research has been done on the OV-Watch when compared to urine luteinizing hormone (LH) tests, but the research that does exist shows the OV-Watch is able to predict ovulation as well as the urine LH tests. Also, because the changes in salt content occur days before ovulation, the OV-Watch is able to predict more fertile days than a urine LH test, just like the Clearblue Easy Fertility Monitor (*Est. $170). While some reviewers love not having to remember to take a test every day, some note that the sensor on the back of the watch can be temperamental and needs frequent readjustment. The watch is also described as being "clunky" and needs to be strapped tightly to a woman's wrist for it to work properly. Some users question the accuracy of the watch, saying its results did not correlate with other ovulation prediction methods. Lastly, the OV-Watch can get expensive, with the initial cost of the watch and replacing the sensor each menstrual cycle. If the cost isn't a deterrent, but the user wants a fertility monitor with more research behind it, the Clearblue Easy Fertility Monitor may be a better choice.
Scientific research and reviews are less extensive with the OV-Watch, but we did find a helpful article on USPharmacist.com that details the clinical studies supporting its use. About.com's pregnancy guide reviews the OV-Watch and provides her personal experience using the watch when compared to a urine LH test. We also found reviews on JustMommies.com and Amazon.com that outline the pros and cons of the device.

This article describes traditional fertility monitoring and details the OV-Watch Fertility Predictor and the clinical studies that support its use. The OV-Watch works by sensing the change in chloride ions in the sweat as it sits on the skin and then identifying a six-day fertile window. According to the clinical studies they cite, the OV-Watch works as well as urine luteinizing hormone (LH) detection kits, and it is able to detect more fertile days than the LH kits.

Robin Elise Weiss, About.com's pregnancy guide, gives the OV Watch Fertility Predictor a rating of 4 out of 5 stars. She says it predicted her fertility the same as a urine LH testing kit she used concurrently and was easy to use. On the plus side it provided four more fertile days than the standard LH testing, but she says the initial expense is high and you do have to replace the sensor monthly. Overall she says the OV Watch works well, though she wishes it was a little less clunky and a bit more fashionable.

A quick search of ovulation tests at Amazon.com brings up several ovulation kits, pregnancy tests and fertility devices. The OV-Watch Fertility Starter Kit gets good ratings, but many of the reviews are mixed. Some users found the watch easy to use, and they conceived right away. Others had difficulty with the sensor falling out and said the OV-Watch was inaccurate when compared to urine luteinizing hormone (LH) tests.
