先前的研究表明，接受生育意识方法指导的女性可以识别每个月经周期的宫颈粘液排出高峰日，并且高峰日与排卵日的其他指标高度一致。然而，以前的研究招募了有经验的生育意识方法使用者，或者没有完全盲法。评估宫颈黏液高峰日与排卵日（尿促黄体激素激增后1天）之间的一致性。本研究是对Creighton模型生育护理™系统（CrM）的随机试验数据的二次分析，该试验于2003-2006年进行，针对试图怀孕的女性。以前没有追踪宫颈粘液经验的妇女每天使用粘液特征的标准化评估记录外阴观察，最长可达七个月经周期。使用了四种方法来确定高峰日。参照日被定义为在尿液中黄体生成素（LH）激增的第一个确定日之后的一天，盲目评估。计算排卵高峰日与参照日之间的一致性百分比。57名妇女共187个完整周期。女性在117个（63%）周期中确定了高峰日，专家在185个（99%）周期中确定了高峰日，计算机算法在187个（100%）周期中确定了高峰日。117个周期中，25%的女性选择的高峰日与参照日相同，58%的周期在±1天内，84%的周期在±2天内，87%的周期在±3天内，92%的周期在±4天内。专家选择的±1天和±4天的一致性分别为50%和90%，计算机选择的峰值日分别为47%和87%。妇女每天跟踪宫颈粘液是确定估计排卵日的低成本替代方法。
Previous research has demonstrated that women instructed in fertility awareness methods can identify the Peak Day of cervical mucus discharge for each menstrual cycle, and the Peak Day has high agreement with other indicators of the day of ovulation. However, previous studies enrolled experienced users of fertility awareness methods or were not fully blinded. To assess the agreement between cervical mucus Peak Day identified by fertile women without prior experience on assessing cervical mucus discharge with the estimated day of ovulation (1 day after urine luteinising hormone surge). This study is a secondary analysis of data from a randomised trial of the Creighton Model FertilityCare™ System (CrM), conducted 2003–2006, for women trying to conceive. Women who had no prior experience tracking cervical mucus recorded vulvar observations daily using a standardised assessment of mucus characteristics for up to seven menstrual cycles. Four approaches were used to identify the Peak Day. The referent day was defined as one day after the first identified day of luteinising hormone (LH) surge in the urine, assessed blindly. The percentage of agreement between the Peak Day and the referent day of ovulation was calculated. Fifty-seven women with 187 complete cycles were included. A Peak Day was identified in 117 (63%) cycles by women, 185 (99%) cycles by experts, and 187 (100%) by computer algorithm. The woman-picked Peak Day was the same as the referent day in 25% of 117 cycles, within ±1 day in 58% of cycles, ±2 days in 84%, ±3 days in 87%, and ±4 days in 92%. The ±1 day and ± 4 days’ agreement was 50% and 90% for the expert-picked and 47% and 87% for the computer-picked Peak Day, respectively. Women’s daily tracking of cervical mucus is a low-cost alternative for identifying the estimated day of ovulation.
