An independent assessment of the CUE Monitor (Zetek, Aurora, Colorado) as an ovulation predictor was made with emphasis on its potential role in "natural family planning". The device provides a digital measurement of the electrical resistance of saliva and vaginal secretions. Twenty-nine menstrual cycles from 11 regularly cycling women were monitored with basal temperatures, urinary LH, pelvic ultrasound and the CUE monitor. Patterns of peak salivary electrical resistance were able to predict ovulation on average 5.3 (+/- 1.9 SD) days in advance. Despite variations in total length of the follicular phase from cycle to cycle, the within-subject variation of this predictive interval was quite small. Nadirs in the electrical resistance of vaginal secretions occurred within 2 days of ovulation in all but one patient. Variation in this interval from cycle-to-cycle was small as well. We propose an algorithm for the use of these intervals in "natural family planning" that could safely reduce the monthly abstinence period of present methods. The simplicity, objectivity and consistency of this device could result in their greater general acceptance.
对CUE监测仪（Zetek公司，科罗拉多州奥罗拉市）作为排卵预测器进行了独立评估，重点关注其在“自然计划生育”中的潜在作用。该设备可对唾液和阴道分泌物的电阻进行数字测量。对11名月经周期规律的女性的29个月经周期进行了基础体温、尿促黄体生成素、盆腔超声和CUE监测仪的监测。唾液电阻峰值模式平均能够提前5.3（±1.9标准差）天预测排卵。尽管不同周期卵泡期的总长度存在差异，但该预测间隔在个体内的变化相当小。除一名患者外，所有患者阴道分泌物电阻的最低点均出现在排卵后2天内。该间隔在不同周期之间的变化也很小。我们提出了一种在“自然计划生育”中使用这些间隔的算法，该算法可以安全地缩短现有方法的每月禁欲期。该设备的简单性、客观性和一致性可能会使其得到更广泛的接受。
