Increased pregnancy rate with use of the Clearblue Easy Fertility Monitor

At home testing: optimizing management for the infertility physician

“…C Accuracy B Able to predict ovulation at a rate of 90%-100% (37,38). Therefore, by evaluating both estrone-3-glucuronide and LH, the Clear Blue Easy Fertility Monitor predicts both ovulation by the determination of the LH surge as well as the most fertile days preceding ovulation by determination of estrone-3-glucuronide levels.…”

“…Another study (40) noted that the device could predict the days of peak fertility in more than 75% of women. Another prospective and randomized study (38) showed significantly higher pregnancy rates (PR) with women using the Clear Blue Easy Fertility Monitor when compared with a control group who had access to other over-the-counter ovulation predictor kits.…”

Characteristics of the Menstrual Cycle After Discontinuation of Oral Contraceptives

“…5 Fertility awareness methods can be used to enhance couples chances to achieve pregnancy. 6 These methods use one or more of several natural biomarkers [i.e., variations in cervical mucus characteristics, BBT, cervical checks, and home urinary hormonal kits that measure estrone-3-glucuronide (E3G) and luteinizing hormone (LH) levels] to determine the fertile window in the cycle or the days when a couple is likely to conceive. 7,8 Among these biomarkers, the presence of estrogen-stimulated cervical mucus is particularly relevant to achieve pregnancy.…”

Efficacy of the Marquette Method of Natural Family Planning

“…Accuracy studies have shown that the markers of fertility (E3G and LH) from the EHFM correlate well with the gold standard of ovulation detection through serial ultrasound of the developing follicle and with serum levels of LH (Behre et al, 2000). Recent studies have demonstrated a significantly higher pregnancy rate (over 3 months) with use of the EHFM compared with chance (Robinson, Wakelin, & Ellis, 2007) and a high acceptability when used to achieve pregnancy (Severy, Robinson, Findley-Klein, & McNulty, 2006). The EHFM is sold and marketed in the United States, Canada, and Europe.…”
