Urine-Based Ovulation and Pregnancy: Point-of-Care Testing
by Samantha F. Eichner and Erin M. Timpe
Our AssessmentThis review article compiles data from articles, textbooks and studies from the past 40 years to provide a comprehensive look at home ovulation prediction and pregnancy tests. Urine luteinizing hormone (LH) tests are found to be more accurate in detecting ovulation when compared to other fertility methods such as following changes in basal body temperature or vaginal or cervical mucus, salivary ferning or calendar calculation. Though much of the information on LH tests is general, the Clearplan Easy Ovulation Kit, now Clearblue, is singled out for its high sensitivity to LH in consumer testing. Monitors that detect urine LH and estrone-3-glucuronide (E3G), such as the Clearplan Easy Fertility Monitor, now Clearblue, are accurate at detecting not only ovulation but also the fertile window. The greatest drawback to the fertility monitor, however, is its high initial cost.
Devices for Home Evaluation of Women's Health Concerns: Ovulation Prediction
by Kelly L. Scolaro, et al.
Our AssessmentThis in-depth clinical review describes various ovulation testing methods and how they work. Benefits and limitations of each are listed as well as the results of several medical studies. Although a few brands are specifically mentioned, the article focuses more on fertility prediction techniques in general. Prediction methods include basal body temperature (BBT) monitoring, urine luteinizing hormone (LH) tests, urine LH and estrone-3-glucuronide (E3G) monitoring, saliva testing and a combination of saliva and cervical mucus monitoring. For urine LH and E3G monitoring, the Clearblue Easy Fertility Monitor is chosen as a favorite because it is easy to use, has clear results and provides more information for the patient, despite its high cost. Urine LH tests are reviewed in general, though the Clearblue Easy is found to be the most sensitive at 22 mIU/ml per a previous study. Saliva microscopy is found to be inexpensive but also difficult to read and to use to define the fertile window. BBT charting, urine LH tests and the Clearblue Easy Fertility Monitor are preferred over saliva testing and the OvaCue Fertility Monitor (a saliva and cervical mucus monitor).
When the Test Really Counts
by Editors of ConsumerReports.org
Our AssessmentEditors of ConsumerReports.org evaluate both pregnancy tests and ovulation test kits in this informative report.

Increased Pregnancy Rate with Use of the Clearblue Easy Fertility Monitor
by Janet E. Robinson, Melanie Wakelin and Jayne Ellis
Our AssessmentThis scientific study looked at the effectiveness of the Clearblue Easy Fertility Monitor in helping couples to conceive. More than 300 women were provided the monitor while another group of more than 300 women were not as a control group. Both groups were allowed to use any other methods they wished to increase their fertility. After two cycles, the cumulative pregnancy rate for the Clearblue Easy Fertility Monitor group was 22.7 percent, while for the control group it was 14.4 percent. Even women who had been trying to conceive for more than a year had an increased rate of pregnancy. No other fertility device, such as basal body temperature, cervical mucus or the calendar method, was shown to increase the chance of conception. The only other factor apart from the Clearblue Easy Fertility Monitor that significantly predicted an increase in the rate of pregnancy was how long a woman had been trying to conceive. A woman who had been trying to conceive for less than six months was more likely to conceive than a woman who had been trying for longer than six months. Of note, the authors of this study work for Unipath, the manufacturer of the Clearblue Easy Fertility Monitor.
Reliability of Ovulation Tests in Infertile Women
by Ellade Guermandi et al.
Our AssessmentThis study follows the menstrual cycles of 101 infertile women and compares the ability of basal body temperature (BBT), urine luteinizing hormone (LH) tests and blood tests for progesterone to detect ovulation. The standard used for detection of ovulation was transvaginal ultrasound and the urine LH kit used in this study was the Clearplan Ovulation test (now Clearblue). The LH peak occurred before ovulation as seen by ultrasound in all cases, and 100 percent of the LH peaks occurred within three days of ovulation. Following the lowest point of BBT was a poor indicator of ovulation.
Prediction of Ovulation by Urine Hormone Measurements with the Home Use ClearPlan Fertility Monitor: Comparison with Transvaginal Ultrasound Scans and Serum Hormone Measurements
by H.M. Behre et al.
Our AssessmentThis study evaluates the ability of the ClearPlan Easy Fertility Monitor, now known as Clearblue, to determine ovulation when compared with hormone measurements and vaginal ultrasound scans. During the two peak fertility days listed by the monitor, ovulation occurred 91.1 percent of the time. Peak fertility never occurred after ovulation. Of note, Unipath Ltd, the manufacturer of the ClearPlan Easy Fertility Monitor, supported this study.
Evaluation of the Accuracy of the Home Ovulation Detection Kit, Clearplan, at Predicting Ovulation
by K. Gudgeon, L. Leader and B. Howard
Our AssessmentThis scientific study compares the Clearplan, now Clearblue, Ovulation test with basal body temperature (BBT) and cervical scoring for predicting ovulation. The accuracy of each method was determined by daily serum luteinizing hormone (LH) measurements. Clearplan was the most accurate at predicting ovulation, and in 96 percent of cases predicted ovulation within two days of the serum LH surge. Though this study is more than 20 years old, it is the foundation for the accuracy of the Clearplan, now Clearblue, Ovulation Test.
Natural Family Planning: Suitability of the CUE Method for Defining Time of Ovulation
by Jorge E. Moreno , Firyal S. Khan-Dawood and Joseph W. Goldzieher
Our AssessmentThis study examines the accuracy of the CUE method, now known as Ovacue, for determining ovulation. The CUE method works by measuring the electrical resistance in saliva and vaginal mucus, and when compared with urine luteinizing hormone levels and vaginal ultrasound in this study, it was able to adequately detect the fertile phase. Though this study recommends the CUE method as a natural form of birth control, it can also be used when trying to conceive.
Efficacy of Methods for Determining Ovulation in a Natural Family Planning Program
by Maurizio Guida et al
Our AssessmentThough this study does not analyze specific products, it does compare the efficacy of different methods for determining ovulation. Researchers found that urine luteinizing hormone (LH) correlated 100 percent with ovulation as determined by transvaginal ultrasound. Self-assessment of cervical and vaginal mucus correlated less than 50 percent of the time, and salivary ferning less than 40 percent of the time with ovulation.
The Usefulness of a Urine LH Kit for Ovulation Prediction During Menstrual Cycles of Normal Women
by Paul B. Miller and Michael R. Soules
Our AssessmentThis study examines the accuracy of urine luteinizing hormone (LH) tests in predicting ovulation when compared to transvaginal ultrasound, and LH and progesterone levels as determined by a blood test. Researchers found that urine LH tests were able to reliably predict ovulation within 48 hours. Though no specific urine LH test is recommended, the study does verify the validity of using urine LH tests to predict ovulation.
A Comparison of the Fertile Phase as Determined by the Clearplan Easy Fertility Monitor and Self-Assessment of Cervical Mucus
by Richard J. Fehring, Kathleen Raviele, Mary Schneider
Our AssessmentThis study compares the fertile phase of the menstrual cycle as estimated by the Clearplan Easy Fertility Monitor, now Clearblue, and self-assessment of cervical mucus. Each method provided similar results, though the fertility monitor was found to underestimate the fertile window, while self-assessment of cervical mucus overestimated the fertile window.
Accuracy of the Peak Day of Cervical Mucus as a Biological Marker of Fertility
by Richard J. Fehring
Our AssessmentThis review analyzed the data from four published studies to assess the accuracy of using cervical mucus to determine the peak day of fertility. When compared with urine luteinizing hormone (LH), researchers found the self-determined peak day of cervical mucus occurred on the same day as the LH surge.
The Timing of the "Fertile Window" in the Menstrual Cycle: Day Specific Estimates from a Prospective Study
by Allen J. Wilcox, David Dunson, Donna Day Baird
Our AssessmentThis article tests the traditionally held belief and clinical guidelines that a woman ovulates at the midpoint of her menstrual cycle. During their study, researchers found that between days 6 and 21, a woman has a 10 percent probability of being in her fertile window, the five days before ovulation and the day of ovulation itself. In addition, even in women with normal menstrual cycles, the day of ovulation could vary widely. Though this study did not test any ovulation predictors or fertility monitors, it does provide the foundation for the necessity of such devices.
Advice and Devices: Fertility Monitoring Update for the Practicing Pharmacist
by Genine Thormahlen, Pharm. D.
Our AssessmentThis presentation is written by Genine Thormahlen, a doctor of pharmacy at the University of Montana, to inform pharmacists about the various types of fertility monitoring devices. She describes and compares seven different devices with suggestions for which patients are well suited to each type as well as limitations of each, but she does not rate them. The author says, in summary, that all ovulation predictor tests are equally effective, but some of the studies that she quotes say otherwise. Studies of saliva microscopes, for example, suggest that they aren't as reliable or easy to interpret as other devices. The Clearblue Easy Fertility Monitor, on the other hand, is shown to be reliable in studies and is able to give a five-day warning of ovulation.

Advanced Technology for Fertility Prediction
by Jaclyn Lennard , Jennifer Lind and Marlon Honeywell
Our AssessmentThis article describes traditional fertility monitoring and then 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 identifies a six-day fertile window. According to the clinical studies the researchers cite, the OV-Watch works as well as urine luteinizing hormone (LH) detection kits and is able to detect more fertile days than the LH kits.
Clearblue Easy Fertility Monitor Review
by Robin Elise Weiss
Our AssessmentRobin Elise Weiss, About.com's pregnancy guide, gives the Clearblue Easy Fertility Monitor a rating of 4.5 stars out of 5. She says that it is accurate and easy to use but expensive. Weiss used the monitor to help herself conceive, but she doesn't compare it to any other ovulation test. (Note: ConsumerSearch is owned by About.com, but the two do not share an editorial affiliation.)
OV Watch Fertility Predictor – Ovulation Prediction Watch
by Robin Elise Weiss
Our AssessmentRobin 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 as well 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.
