人体排卵通常发生于月经周期第12～16天之间,但要精确地测定则存在困难。基础体温图虽然Van de Velde 早在1904年描述,但至今仍是检测排卵最简单,且最普遍采用的方法。一般认为因产热引起的基础体温变化发生在 LH 峰之后两天。这种方法虽然简便,但不能准确地确定排卵的时间,以致使患者判断错误。作为预测排卵的指标,宫颈的形态学变化和宫颈粘液在量和质方面的改变现已广泛研究。粘液的产生是有赖于雌激素的,当出现排卵前雌激素峰
Ovulation usually occurs between the 12th and 16th days of the menstrual cycle, but it is difficult to determine accurately. Basal body temperature map Although Van de Velde was described as early as 1904, it is still the simplest and most commonly used method of detecting ovulation. It is generally believed that the change in basal body temperature due to thermogenesis occurs two days after the LH peak. Although this method is simple, but can not accurately determine the time of ovulation, so that patients judge the wrong. As a predictor of ovulation, changes in cervical morphology and cervical mucus in quantity and quality have been extensively studied. Mucus production is dependent on estrogen, when ovulation estrogen peaks
