The objective was to study the characteristics of ultrasonographically detected subendometrial myometrial contractions. The contractions were evaluated by 328 ultrasound scans throughout the menstrual cycle. Reproducibility of these findings were studied in consecutive cycles. Eighteen healthy ovulatory volunteers with proven fertility were evaluated for at least one complete menstrual cycle in the follicular, periovulatory, and luteal phases. Multiple cycles were studied in 10 volunteers. The results showed that the contractions increase in frequency, amplitude, and percentage toward the fundus throughout the follicular and periovulatory phases. The pattern is essentially reversed in the luteal phase. There is reproducibility of these patterns from cycle to cycle. We conclude that there is a definite identifiable pattern of subendometrial myometrial contractility that varies with the phases of the normal menstrual cycle and recurs in a similar fashion from cycle to cycle.
目的是研究超声检测到的子宫内膜下肌层收缩的特征。在整个月经周期中通过328次超声扫描对收缩情况进行评估。在连续的周期中研究这些发现的可重复性。对18名已证实有生育能力的健康排卵志愿者在卵泡期、围排卵期和黄体期进行了至少一个完整月经周期的评估。对10名志愿者进行了多个周期的研究。结果显示，在整个卵泡期和围排卵期，收缩的频率、幅度和向宫底的百分比均增加。在黄体期，这种模式基本相反。这些模式在不同周期之间具有可重复性。我们得出结论，存在一种明确可识别的子宫内膜下肌层收缩模式，它随正常月经周期的阶段而变化，并且在不同周期中以相似的方式反复出现。
